Walkthrough videos

Short narrated walkthroughs of real jobs, 24 to 69 seconds each. Captions are on, so they work with the sound off. Each one plays in a pop-up; the calculator pages have the same Watch how it works button.

  • Size a breather for a 500-gallon hydraulic reservoir, check the existing port, and see which units last a 12-month change interval.

    Open breather sizing →
  • Set a 17/15/12 target, enter reservoir, flow, oil and temperature, and get a filter grade and housing checked for hot and cold pressure drop.

    Open ISO 4406 cleanliness (Suggest Filter + Housing) →
  • Look up a 6309, enter speed and temperature once, and get a ranked grease recommendation for an electric motor.

    Open bearing lookup →
  • Use the AGMA 9005 pitch-line velocity method on a helical gearbox at 50 °C to get ISO VG 320, then rank matching EP gear oils.

    Open gearbox oil viscosity →
  • Pick two ISO VG 100 oils from the built-in list and compare them: VI 99 vs 153, and 12.9 vs 16.2 cSt at 200 °F.

    Open viscosity comparator →
  • Look up deep-groove 6309 (Fafnir), load its multipliers, set shaft speed to 1800 RPM: BPFO 91.11 Hz, BPFI 148.89 Hz, BSF 58.65 Hz, FTF 11.40 Hz.

    Open defect frequencies →
  • Pick a 23136 spherical roller for a 60-inch dryer can on ISO VG 220 oil: at about 3,000 FPM the oil must run no hotter than 133 °F to stay in the target zone, and at 160 °F kappa drops to 1.32.

    Open drum oil temperature →
  • A 120-gallon ISO VG 220 sump took 15 gallons of ISO VG 68 and is down to 187.0 cSt; draining 37.8 gal and refilling with ISO VG 320 brings it back to 220.3 cSt.

    Open viscosity blending (Reservoir Correction) →
  • Flush a 1-inch Schedule 80 line with Mobil DTE 25 (ISO VG 46) at 140 °F: Reynolds number 1,652 (laminar) at 10 GPM, turbulent flow needs 24.2 GPM, and 30 GPM reaches 4,957, an acceptable flush.

    Open Reynolds flush →
  • Convert NAS 1638 class 6 to about ISO 4406 17/15/12 and AS4059 Table 1 class 6, then turn a lab result of 19/17/14 back into about NAS class 8, well above the class 6 spec.

    Open ISO 4406 cleanliness (code converter) →
  • Search one hydraulic filter element part number (microglass, 12 µm class) and get 252 equivalents from 14 brands, 34 of them published interchanges.

    Open filter cross-reference →
  • Stock the plant shelf with 3 oils (an ISO VG 220 EP gear oil and two hydraulic oils) and 3 greases (motor, EP and coupling), so recommendations prefer what is on hand.

    Open mill lubricant inventory →
  • A heavily loaded gearbox at 140 °F with a 60 cSt minimum and an 80 x 140 mm spherical roller bearing at 1800 RPM: the top pick is the in-stock ISO VG 220 EP gear oil, 80 cSt at temperature against 60 required.

    Open lubricant recommendation →
  • A 440 frame motor at 1800 RPM in severe, around-the-clock service, sized by bearing number with an NU318 roller at the drive end and a 6318 ball opposite: both ends regrease every 1,850 hours, the ball end's shot drops to 0.72 oz, the lubricators run at 17.9 and 9.0 cc a month, and the on-shelf Chevron Black Pearl SRI 2 comes first.

    Open motor bearing greasing →
  • A fan's 22220 spherical roller (100 mm bore) at 1200 RPM carrying 20,000 N: mid-range friction gives a 2.25 N·m moment, 283.5 W of heat, about 967 BTU/hr into the oil and housing.

    Open bearing friction and heat →
  • A 6309 ball bearing (100 x 45 x 25 mm) at 1750 RPM in washdown water at 140 °F and hard to reach: re-grease weekly at 0.29 oz, the shot scaled to the rounded interval so grease per month stays the same, plus polymer-filled bearing options by maker.

    Open re-grease interval →
  • A process pump's 6309 ball bearing (55.3 kN rating, 4 kN load, 3560 RPM) gets a basic L10 life of 12,371 hours; with κ 2, the mean diameter and fatigue load limit, normal cleanliness gives aISO 10.4 and about 129,000 hours, typical contamination just 1.13 and 14,000.

    Open component life →
  • A 22220 spherical roller with C3 clearance on a k6 shaft: in Running checks an inner ring 18 °F hotter than the outer costs 0.00081 in, leaving 0.00309 in running, and a 12,000 lbf load at 54 °F over ambient needs 1.25 thousandths of grip that a loose k6 can't give, so the inner ring may creep.

    Open bearing clearance →
  • In the root cause tool's Causes tab, the ISO 15243 damage picker set to abrasive wear shows what the damage looks like and the causes to check, with the lubrication ones tagged, then adds hard particles and inadequate lubrication as physical observations.

    Open root cause analysis →
  • A hydraulic fitting dripping 60 drops a minute of $15-a-gallon oil, plus 2 hours of cleanup a week at $45 and $2/gal disposal, loses nearly 2,000 gallons a year and costs $38,525.

    Open leak cost →
  • A 22220 bearing (180 x 100 mm) on a gearbox output shaft at 300 RPM with a κ target of 2: the minimum required viscosity is 33.43 cSt at operating temperature, so the oil must deliver 66.86 cSt.

    Open minimum viscosity →
  • For Falk Steelflex grid couplings the calculator calls for Mobilgrease XTC; a pump with a 2.5 in shaft fits a 1070T at the smallest, which takes 4 oz of grease, one 14-oz tube.

    Open coupling grease fill →
  • The built-in example, an 18-gallon paper machine dryer gearbox sampled 580 hours apart with two top-offs: about 74% of the old oil remains, so iron going from 42 to 55 ppm is really 47.78 ppm per 1,000 hours, flagged watch.

    Open oil analysis wear rate →
  • A 22220 spherical roller (100 mm bore) at 1200 RPM with 4,500 lbf of load, oil in at 100 °F and out at 140 °F: carrying the friction heat away with a 22 °C rise takes 0.58 L/min, about 0.15 gal/min.

    Open forced circulation oil flow →
  • Look up a 22218 spherical roller by number alone: 3.5433" bore, 6.2992" OD, 1.5748" wide, C = 74,412 lbf, limit speed 3,800 RPM, and the matching SNL 218 / SAF22218 / SNV160 housings.

    Open bearing lookup →
  • Pump at 30 psi on a 1 in line, bearing inlet 25 ft up on a ½ in line, SG 0.87 at 5 GPM: about 20.2 psi at the bearing as a best case, before pipe friction, filters, fittings and valves.

    Open Bernoulli balance →
  • A 4 in × 3 in journal, 0.006 in diametral clearance, 1800 RPM, 2,500 lbf, ISO VG 46 at 60 °C (about 21 cSt): hydrodynamic film likely, h_min 36.5 μm, ε 0.521, about 0.72 hp of oil shear.

    Open journal bearing →
  • A 100 mm steel ring in an aluminum bore with 0.0005 in interference at 70 °F opens to 0.00288 in clearance at 200 °F: the bore grows faster than the shaft, so the fit loosens and the ring can creep.

    Open thermal expansion and fit →
  • A 120 in sample line with a ¼ in inside diameter needs a 33 fl oz purge (10× line volume), about 8¼ sample bottles, caught in a waste bottle before the sample.

    Open sample tube flush →
  • Motor at 1780 RPM, 5 in drive sheave, 14 in fan sheave: the fan shaft turns 635.7 RPM (2.8:1) and the belt runs at 2,330 FPM. Use the shaft speed, not the motor speed, in the re-grease and viscosity tools.

    Open unit converter →
  • Mobil DTE 25 is an ISO VG 46 mineral hydraulic oil (VI 98, 44.2 cSt at 40 °C). Every equivalent shown is the same ISO VG 46 grade that meets or beats it; tick food grade for NSF H1 VG 46 options.

    Open lubricant specs and equivalents →
  • 19 T pinion, 77 T gear, 1780 RPM: gear mesh frequency 563.7 Hz, a hunting-tooth design, sidebands at 29.67 Hz (pinion) and 7.32 Hz (gear), then the gear mesh spectrum and a simulated polar view of a cracked tooth.

    Open gear mesh frequencies →
1 · First visit
  1. Read the disclaimer once and acknowledge it (stored in this browser only).
  2. Use the header controls for light/dark and optional larger text (A+).
  3. Open Inventory only if you want recommendations biased to what is on the shelf. Default is nothing stocked.
Nothing is uploaded to a server. Calculations and inventory live in local browser storage on this device.
2 · Typical job (bearing → lube)
  1. Start at Bearing lookup — SKF-style numbers and ABMA size decoding both work.
  2. When a bearing is selected, the job bar under the header carries geometry and speed into the next tools.
  3. Common next steps:
  4. Or open Start a job and pick the path that matches the machine.
3 · Facility inventory

Recommendations prefer products you mark as on the shelf. Unchecked items only surface when nothing stocked fits.

  • Filter by brand when the mill has a preferred supplier.
  • On the recommendation page, the inventory panel collapses once something is stocked — click the title bar to open it again.
  • You can also manage stock from the dedicated Inventory page.
4 · Drum / roll oil-temp chart
  1. Select the bearing (or enter mean diameter), roll/drum OD, ISO VG + VI, and max FPM.
  2. Press DRAW K-ZONE CHART — the chart does not auto-redraw while you type (avoids mid-entry alerts).
  3. Hover for κ, oil viscosity at cursor temp, and ν₁ context. Drop pins if you want setpoints; export CSV when useful.
  4. After rotating a tablet, hit DRAW again if the plot looks stretched.
5 · LubeLabel & LubeMapper

LubeLabel builds printable identification for greases and oils (color, shape, product data).

LubeMapper places lube units, gearboxes, filters, and related assets on a floor plan.

SAP Plan Builder drafts standard procedures and SAP maintenance-plan load-sheet rows (CSV/PDF) — a free plant-floor helper, not a CMMS.

  • Label products publish into a shared catalog in this browser so Mapper can pick them.
  • Mapper canvas is in pixels. New levels can lock size to an uploaded plan image; changing a background on an existing floor asks whether to resize the canvas to match.
  • Use Edit mode to add areas, levels, and units. Export/backup from the ⋮ menu if you need a copy off the device.
6 · Oil analysis normalizer
  1. Open Oil analysis. Enter sump volume and the hour meter on the previous and current samples.
  2. Add each top-off between those samples (hours, volume, makeup ppm — 0 if it was new oil).
  3. Type previous and current lab values. Blank rows are skipped.
  4. Normalize samples produces a dilution-corrected equivalent, ppm / 100 h, and ppm at your chosen interval (100–1,000 h).
  5. Use Sample frequency for a next-interval recommendation from criticality, environment, and last severity.
Raw ppm lies when someone dumped five gallons of new oil into the gearbox last week. Normalize first, then compare to your condemning limits.
7 · Other tools (quick map)
  • Component life — ISO 281 L10, linear guides, chains, belts, cylinders, motor insulation, rupture discs.
  • Unit converter — pulley ratio, FPM↔RPM, density/API, length, area/volume (convert or calculate), pressure, temp, force.
  • Journal bearing — clearance, speed, viscosity, density (SG / °API / lb/gal / kg/m³).
  • Tilting pad thrust bearing — Waukesha MS size by thrust load, shaft and RPM; sliding speed, lube mode, babbitt limits.
  • Oil cooler sizing — heat load, air-oil or water-oil ETD, cooler matches across brands, brazed plate swap check.
  • Defect frequencies — vibration orders for rolling bearings.
  • All tools — full list with short descriptions.
8 · Limits & judgment

Results follow common engineering practice (SKF-style viscosity factors, catalog geometry, published oil curves, etc.). They are a starting point, not a substitute for OEM limits, site standards, or your own due diligence.

LubeSuite and its owner are not liable for failures from using these numbers alone. Full wording is on the About & Disclaimer page.
