Product Description

Supporting needle roller bearing is thick outer wall, the high temperature and high nitrogen quenching, high precision separation of the roller from high rigid outer rim of the guide, using the linear contact, roller can be directly in the rolling way easily turn, and can bear huge load. For removing stress, supporting roller outer of the cambered surface design, curve roller with single and double sealing ring, not with seals, sealing with various specifications. With seals storage grease in space, provide from lithium grease lubrication, and extend lubrication interval. Seal material with skeleton nitrile rubber or ST*2, its operating temperature range for - ° C to + **0 ° C or - *0 ° C to + **0 ° C. Tight mounted curve roller can bear a heavy load and high performance running strong.
