How the 89416-M model number is decoded
In SKF catalogue PUB BU/P1 17000, 89416 M denotes a cylindrical roller thrust bearing whose rollers run flat on hardened, ground washers — no radial capacity, one axial direction only, and a minimum axial load of factor A 0.24. Reading the code: the first three digits 894 give the dimension series (extra-heavy 894 series), the last two 16 encode the 80 mm shaft washer bore (code 16 × 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 0.24. Selection arithmetic: C 440 kN against C0 1730 kN gives a C0/C ratio of 3.93 — thrust bearings are chosen on static rating and F_a/C0 more often than on L10 life. Mounting: locate the shaft washer on the 80 mm seat (it rotates and takes an interference fit), leave the housing washer a sliding fit in the 170 mm bore, and check the stack can tilt freely before clamping.
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
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
- shaft-washer creep and fretting corrosion on a soft or undersized shaft shoulder
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
- hard-particle indentation where oil or grease filtration is inadequate
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
Selection pitfalls — read before you substitute
- At 80 mm bore the minimum load (A 0.24) is still small, but a vertical shaft at rest loses it entirely — specify springs or check the rotor weight exceeds F_am at zero speed.
- The 440/1730 kN ratings assume flat, full-support washer seats; a housing face narrower than the 170 mm washer OD invalidates the rating through edge stress.
- Factor A 0.24 is a mounting requirement, not advice: below the minimum axial load the rollers skid at speed — most "mysterious" early thrust failures are unloaded running.
- Do not substitute a thrust ball bearing of the same ISO envelope by rating alone: the cylindrical rollers of 89416 M need different minimum load and lubrication despite the shared 80×170 mm outline.
- 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 89416 M size.
- The 440/1730 kN ratings and 7050 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
Which dimensions does the 89416 M have?
A 89416 M measures 80 mm bore × 170 mm outside diameter × 54 mm width (3.15 × 6.693 × 2.126 in). From SKF catalogue PUB BU/P1 17000: dynamic C 440 kN, static C0 1730 kN, fatigue limit Pu 173 kN, reference speed 900 r/min, limiting speed 1,800 r/min, mass about 7050 g. Raceway diameters Ea 88 mm / Eb 165 mm and minimum load factor A 0.24 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. 89416 M belongs to the extra-heavy 894 series, 80×170×54 mm.
Are the washers of 89416 M separable?
Yes — shaft washer WS, roller-and-cage set and housing washer GS are separate and interchangeable within the size, but never across series: an 811 and an 812 washer for the same bore differ in OD and height.
Can a thrust ball bearing replace the 89416 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.
