Detailed description
NU2304E Bearing characteristics; 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) inner ring or outer ring separable, easy to install and remove. Bearing radial load capacity is big, applies to carry heavy load and impact load, also suitable for high speed rotation.
