Cylindrical Roller Bearings NJ224

Specification

Our advantage:

 1. Bearings specifically designed for use in construction machinery, excavator slewing gearboxes, and wind turbine gearboxes
 2. Capable of simultaneously bearing capacity and rigidity
 3. High-strength, high-quality material
 4. Smooth rotation and low noise.
Product features:

Strong Bearings: The cylindrical roller design can withstand larger bearings than ball bearings of the same size.
1. NJ type bearings, single-rail inner ring (can be used with HJ type loose-rail bearings), allowing for free thermal expansion. It is an ideal free-end bearing, effectively eliminating nut extra caused by thermal expansion and contraction.

3. Separable design: The inner ring, outer ring, and roller assembly can typically be separated, allowing for easier installation and sensing.
4. 50% longer service life compared to other companies' products.
