81284 M-Thrust roller bearing

Thrust cylindrical roller bearings are often combined into high stiffness bearing configurations, which can bear heavy load and vibration load without difficulty. It is only applicable to the parts that bear one side of axial load and low speed, and only to the parts that bear one side of axial load and low speed, such as crane hook, vertical pump, vertical centrifuge, jack, such as crane hook, vertical pump, vertical centrifuge, jack, low speed reducer, etc. The shaft ring, race and rolling body of the bearing are separated, and the speed reducer, etc. The shaft ring, seat ring and rolling element of the bearing are separated and can be installed and removed separately
