The main body is made of GCr15 bearing steel, and the hardness of the needle roller and ring quenching reaches HRC60-65. The cage is made of low carbon steel or reinforced nylon, which meets national standards such as JB/T8877.
The axial load of NKIA and NKIB series bearings shall not exceed 25% of the radial load. The support for alternating axial loads must be installed facing each other. The thrust bearing components must be subjected to a preload of 1% of the axial basic rated static load. When using a plastic cage (suffix TN), continuous operation should not exceed the operating temperature+120 ° C. The thrust bearing components should move freely in the bearing seat.
