Product summary
81120 TN: cylindrical roller thrust bearing, brand SKF. Bore diameter d 100 mm, outside diameter D 135 mm, mounting height T 25 mm. Dynamic load rating C 156 kN, static load rating C0 630 kN, limiting speed 2400 rpm, weight 0.95 kg.
Line contact between cylindrical rollers and the washers: high axial load capacity at a low height.
Where it is used
Low-speed assemblies with high axial force: screw presses, jacks, extruders and injection moulding machines, vertical mills, drilling rig swivels, crane hooks.
When not to use
It takes no radial load and does not tolerate tilting of the washers: lack of parallelism causes edge contact and spalling of the roller ends, so it does not replace a spherical roller thrust bearing. In a fast assembly it does not replace a thrust ball bearing: there is sliding along the roller length, so heat generation increases.
