Spherical Roller Thrust Bearing 1.GCr15, GCr15SiMn, G20Cr2Ni4A 2.Brand: ZWA & OEM 3.ISO9001:2008 4.ID:100mm-1500mm Same as spherical roller bearings, housing washer raceway surface is a spherical one which takes the same point of bearing Same as spherical roller bearings, housing washer raceway surface is a spherical one which takes the same point of bearing central axle as the spherical center point. Different with other thrust bearings, these bearings are characterized by its high axial load carrying capacity, meanwhilee,they can carry certain radial load, however, the radial load should not exceed 55% of the axial load. The track of the housing washer is spherical, and the rolling bodies are spherical shaped. This makes the bearing self-aligning and therefore insensitive to misalignment. If the load P and P0 do not exceed 0.05 Co, and the shaft washer rotates, then the following angles of misalignment are permissible : Bearing diameter series Aligning angle 200 series 300 series 400 series 1°- 1. 5° 1.5°- 2° 1.2°- 3° The figures with small values are suitable for comparatively large size bearings, and when the load increases, the permissible misaligment shall decrease. Applications of these bearings can be found in hydroelectric generators, vertical motors,propeller axle of vessels, tower cranes and squeezing presses Design features: LHB spherical roller thrust bearings in assembling a large number of asymmetric rollers, and special Raceway has an excellent combination. Therefore can withstand the heavy load, and allows a relatively high speed. Spherical roller thrust bearings according to size and different series, there are two forms design; Model E suffix for the bearings, equipped with a ram Gangchuang-holder, and roller shaft circle formed an inseparable components. Bearing all other with copper or steel cage from the fixed axis circle hole in the sleeve to guidance, and with the roller shaft circle Cage composition of the device can not be separated. We can produce the diameter from 60mm 1 600mm LHB Spherical roller thrust bearings. Following is the internal structure of LHB different product descriptions.
