How the 89313-TN model number is decoded
Where a thrust ball bearing of the same envelope is exhausted, 89313 TN replaces the ball complement with cylindrical rollers: 65 mm bore, 115 mm OD, rated 640 kN static for steady hook and screw loads. SKF thrust-roller numbering mirrors the ball 511/512 plan with 811/812: 812 is the higher (heavier) section per bore, and 893/894 are the very heavy series — 89313 TN sits in the heavy 893 series. 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. Minimum axial load is explicit at factor A 0.033: below F_am = A·n² (or the catalogue's slow-speed floor) the cylindrical rollers skid; springs or the rotor's own weight are part of the selection, not an accessory. Mounting: locate the shaft washer on the 65 mm seat (it rotates and takes an interference fit), leave the housing washer a sliding fit in the 115 mm bore, and check the stack can tilt freely before clamping.
Typical equipment & failure modes
Common applications
- vertical electric motor and pump shafts whose rotor weight loads one bearing
- extruder and injection press screw thrust blocks at low speed
- rolling-mill screwdown mechanisms and press adjusters
- slewing and turntable pivots with predominantly axial force
Known failure patterns
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
- washer back-face fretting where the seat is too narrow to support the full ring face
- grease churning and overheating when a high-speed thrust position is over-packed
- 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 65 mm bore the minimum load (A 0.033) 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 153/640 kN ratings assume flat, full-support washer seats; a housing face narrower than the 115 mm washer OD invalidates the rating through edge stress.
- Factor A 0.033 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 1,400 r/min reference speed is the thermal criterion under load, the 2,800 r/min limiting speed is mechanical and oil lubrication typically raises the usable figure.
- Do not substitute a thrust ball bearing of the same ISO envelope by rating alone: the cylindrical rollers of 89313 TN need different minimum load and lubrication despite the shared 65×115 mm outline.
- The 153/640 kN ratings and 1350 g mass are SKF catalogue values transcribed from ch. 11.1 of PUB BU/P1 17000 (PDF table page 890); 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 89313 TN have?
A 89313 TN measures 65 mm bore × 115 mm outside diameter × 30 mm width (2.559 × 4.528 × 1.181 in). From SKF catalogue PUB BU/P1 17000: dynamic C 153 kN, static C0 640 kN, fatigue limit Pu 65.5 kN, reference speed 1,400 r/min, limiting speed 2,800 r/min, mass about 1350 g. Raceway diameters Ea 71 mm / Eb 113 mm and minimum load factor A 0.033 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. 89313 TN belongs to the heavy 893 series, 65×115×30 mm.
Are the washers of 89313 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 89313 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.
