NJ310 cylindrical roller bearing heavy load

single row roller bearing 50x110x27mm

one-rib inner ring roller bearing

Product Description

1. Product Overview

The NJ310 single‑row cylindrical roller bearing adopts NJ‑type structural design with one‑rib inner ring. It can withstand heavy radial load as well as limited one‑direction axial load, and allows certain axial displacement between inner and outer rings to absorb shaft thermal expansion.

It is widely used in industrial gearboxes, reducers and general heavy‑load rotary shaft assemblies.

3. Key Advantages

NJ single‑rib inner ring structure supports heavy radial load and moderate unidirectional axial force
Permits relative axial sliding between inner and outer ring to compensate shaft thermal elongation
Stamped steel cage features good impact resistance and stable rotation performance
Standard mounting dimensions for convenient replacement and interchangeability
Compact structure adapts to various general industrial transmission arrangements
Custom design available (C3 clearance, brass cage, OEM laser marking)

👉 Helps reduce maintenance cost and improve machine performance

4. Applications

This bearing is widely used in:

Industrial gear reducers, gearboxes and motor main shaft assemblies
Construction machinery auxiliary transmission and mining light‑load rotary equipment
Fan and blower units, pulp machinery and general engineering machinery
Conveyor drive systems and machine tool intermediate rotary shaft components

👉 Ideal for customers looking for reliable and long‑life bearing solutions
