Cylindrical Roller Bearings NJ222

Cylindrical roller bearing NJ222

Specification

Our Advantages :

 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.

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.
2.Performance: The coefficient of friction is relatively low, and through optimized design (e.g., models using copper alloy cages or engineering plastic high-speed cages, such as NJ222EM, NJ222ECML, etc.), it can be adapted to higher speeds.
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.

Bearing inspection

We place great emphasis on quality control and have established a comprehensive quality inspection system. From raw material warehousing to delivery,
every purchase and every bearing undergoes rigorous inspection and testing to ensure that we provide our customers with stable, reliable, and standard-compliant products.

Participating in the
2024 Shanghai bauma Exhibition

At ZHZB, we operate with a comprehensive quality control system at its core. From raw material inspection upon arrival to final product delivery,
every sensor undergoes 100% inspection and accuracy verification, strictly adhering to ISO 9001 and other international standards.
This ensures that we provide reliable bearing components for high-end equipment in industries such as mining, road construction, and wind power.
