How the 89316-TN model number is decoded
In SKF catalogue PUB BU/P1 17000, 89316 TN 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 0.09. Reading the code: the first three digits 893 give the dimension series (heavy 893 series), the last two 16 encode the 80 mm shaft washer bore (code 16 × 5), and TN names the cage execution. The three components are separable and interchangeable within the size: WS shaft washer, K-cage roller set, GS housing washer, all running on flat, square seats; the glass fibre reinforced PA66 TN cage is standard for this size. Selection arithmetic: C 240 kN against C0 1060 kN gives a C0/C ratio of 4.42 — 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
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
- washer back-face fretting where the seat is too narrow to support the full ring face
- abrasive paste forming as dust bypasses the housing seals into the open washer set
- condensation pitting in machines that run intermittently in humid environments
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
Selection pitfalls — read before you substitute
- At 80 mm bore the minimum load (A 0.09) 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 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 89316 TN size.
- the 1,200 r/min reference speed is the thermal criterion under load, the 2,400 r/min limiting speed is mechanical and oil lubrication typically raises the usable figure.
- The 240/1060 kN ratings assume flat, full-support washer seats; a housing face narrower than the 140 mm washer OD invalidates the rating through edge stress.
- Do not substitute a thrust ball bearing of the same ISO envelope by rating alone: the cylindrical rollers of 89316 TN need different minimum load and lubrication despite the shared 80×140 mm outline.
- The 240/1060 kN ratings and 2350 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 89316 TN have?
A 89316 TN measures 80 mm bore × 140 mm outside diameter × 36 mm width (3.15 × 5.512 × 1.417 in). From SKF catalogue PUB BU/P1 17000: dynamic C 240 kN, static C0 1060 kN, fatigue limit Pu 108 kN, reference speed 1,200 r/min, limiting speed 2,400 r/min, mass about 2350 g. Raceway diameters Ea 86 mm / Eb 137 mm and minimum load factor A 0.09 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. 89316 TN belongs to the heavy 893 series, 80×140×36 mm.
Are the washers of 89316 TN 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 89316 TN?
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.
