How the 89322-M model number is decoded
Where a thrust ball bearing of the same envelope is exhausted, 89322 M replaces the ball complement with cylindrical rollers: 110 mm bore, 190 mm OD, rated 1830 kN static for steady hook and screw loads. Reading the code: the first three digits 893 give the dimension series (heavy 893 series), the last two 22 encode the 110 mm shaft washer bore (code 22 × 5), and M names the cage execution. The bearing takes thrust in one direction only — reverse loads lift the roller set off its track; arrange a mirrored second bearing for reversing duty, and keep the applied load above factor A 0.27. Selection arithmetic: C 400 kN against C0 1830 kN gives a C0/C ratio of 4.58 — thrust bearings are chosen on static rating and F_a/C0 more often than on L10 life. In vertical shafts let the rotor weight provide the minimum load where possible; otherwise fit a spring pack above the housing washer, and verify the washer face is flooded with oil at first start.
Typical equipment & failure modes
Common applications
- crane hook crossheads carrying pure hook thrust while the hook swivels
- screw jack and lifting screw thrust positions under slow, steady load
- vertical electric motor and pump shafts whose rotor weight loads one bearing
- extruder and injection press screw thrust blocks at low speed
Known failure patterns
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
- housing-washer rotation scored into an unmachined or loose seating face
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
- condensation pitting in machines that run intermittently in humid environments
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
Selection pitfalls — read before you substitute
- At 110 mm bore the washers are too stiff to conform to a non-square seat: machine the shoulders parallel or the roller ends concentrate load into a narrow stripe across 48 mm.
- Keep the machined brass M cage out of chemical contact with aggressive EP additives beyond its compatibility list; cage damage here redistributes rollers and destroys the washer in hours.
- Do not substitute a thrust ball bearing of the same ISO envelope by rating alone: the cylindrical rollers of 89322 M need different minimum load and lubrication despite the shared 110×190 mm outline.
- Factor A 0.27 is a mounting requirement, not advice: below the minimum axial load the rollers skid at speed — most "mysterious" early thrust failures are unloaded running.
- The separable washers are not interchangeable across series: an 811 and an 812 washer for the same bore differ in OD and height — order WS/GS parts by the full 89322 M size.
- The 400/1830 kN ratings and 6700 g mass are SKF catalogue values transcribed from ch. 11.1 of PUB BU/P1 17000 (PDF table page 892); mounting data — Ea/Eb raceway diameters and the minimum load factor A — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
Can a thrust ball bearing replace the 89322 M?
They share ISO boundary outlines (e.g. 511 vs 811), but the roller bearing needs a higher minimum axial load and different lubrication, and its C/C0 figures are not interchangeable — re-run the selection before substituting.
What ruins a 89322 M in service?
Unloaded running below factor A 0.27 causes skidding; non-square or narrow shoulders fret the washer backs; dry starts and contamination do the rest. Speed ceiling: 1,700 r/min limiting.
Which dimensions does the 89322 M have?
A 89322 M measures 110 mm bore × 190 mm outside diameter × 48 mm width (4.331 × 7.48 × 1.89 in). From SKF catalogue PUB BU/P1 17000: dynamic C 400 kN, static C0 1830 kN, fatigue limit Pu 173 kN, reference speed 850 r/min, limiting speed 1,700 r/min, mass about 6700 g. Raceway diameters Ea 120 mm / Eb 185 mm and minimum load factor A 0.27 guide the seat design.
What is the difference between 811 and 812 series?
811 is the light section and 812 the higher, heavier section for the same bore; 893/894 are the extra-heavy series. 89322 M belongs to the heavy 893 series, 110×190×48 mm.
