29230 E MB Sealed Thrust Bearing , Brass Cage Axial Thrust Bearing ABEC-1
Thrust spherical roller bearings are ideal for applications where conditions include heavy loads, difficulties in establishing or maintaining housing alignment and problems with shaft deflection.Spherical thrust roller bearings have specially designed raceways and accommodate a large number of asymmetrical rollers. The rollers have an optimum conformity with the washer raceways to optimize load distribution along the roller length.Therefore,they can accommodate relatively high speeds, heavy axial loads in one direction and heavy radial loads.The load is transmitted between the raceways at an angle to the bearing axis. Spherical roller thrust bearings are self-aligning and can accommodate misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
Features
Spherical roller thrust bearings are featured by the extremely big axial load carrying capacity and meanwhile they can also carry cetrain radial load.
Typical application
Applications of these bearings can be found in steel industry, mining&construction, papermaking machinery, gearboxes, injection molding machines, motorcycles, crane hooks, pump, centrifuge, jack, speed reducer.
