Heavy Load Cylindrical Roller Thrust Bearing Large Diameter 81148M For Oil Drilling
Description:
ETR Cylindrical roller Thrust Bearing 81148-M, Heavy Load low friction
Cylindrical roller thrust bearings are simple in form and design, they are produced in single row and double row designs. The bearings in the 811 and 812 series are mainly used where thrust ball bearings have insufficient load carrying capacity. Series 811 and 812 consist of a thrust cylindrical roller and cage assembly, the shaft washer and the housing washer. The most vital component of the bearing is the thrust cylindrical roller and cage assembly. The modified line contact eliminates edge stresses at the roller ends.
These are thrust bearings containing cylindrical rollers. They can sustain only axial loads, but they are suitable for heavy loads and have high axial rigidity. The cages are machined brass.
