Product summary
33122: tapered roller bearing, brand SKF. Bore diameter d 110 mm, outside diameter D 180 mm, mounting height T 56 mm. Dynamic load rating C 369 kN, static load rating C0 630 kN, limiting speed 3400 rpm, weight 5.5 kg.
Tapered raceways and rollers whose cone apexes meet on the bearing axis. Carries combined loads: radial and axial in one direction. Can be mounted in pairs, with the clearance or preload set during mounting. Suitable for heavy and shock loads.
Where it is used
Wheel hubs, shafts of bevel-helical and worm gearboxes, machine tool spindles, drums and rollers. Mounted in pairs in an O or X arrangement, with the axial clearance or preload adjusted during mounting.
When not to use
Do not fit it instead of a ball or cylindrical roller bearing: without a second support that closes the axial force, a tapered roller bearing has no preload. The rollers unload and start sliding on the raceway instead of rolling, which leads to scoring and rapid failure. Note that matching d and D proves nothing: a tapered roller bearing is specified by its mounting height T instead of the width B, so the seat width differs and the assembly needs adjustment during mounting.
