Structure Thrust Type Roller Brand Name FAG, KOYO, NACHI, NSK, NTN, SKF, ZWA Bore Size 100 - 1200 mm Outside Diameter 170 - 1500 mm Model Number 29476 Precision Rating P0, P6,P5 Seals Type without seal Number of Row Single Row Place of Origin Liaoning, China (Mainland) Material GCr15, GCr15SiMn, G20Cr2Ni4A Spherical Roller Thrust Bearing1.GCr15, GCr15SiMn, G20Cr2Ni4A2.Brand: ZWA & OEM3.ISO9001:20084.ID:100mm-1500mm Charicteristics : 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.
