Detailed description
NU209E Bearing features: 1. The rollers and raceway for the line contact or offline contact, radial load capacity is large, suitable for under heavy load and shock load. 2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings. (3) on the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to kept under strict control, so as to avoid stress concentration caused by contact. 4. The inner ring or outer ring separable, easy to install and remove.
