Product Overview

The NJ208EM cylindrical roller bearing is a benchmark product among high-performance single-row cylindrical roller bearings, designed specifically for high radial load and continuous high-speed operation scenarios. It boasts excellent reliability and cost performance. As a classic single-row model, its structure of double-rib inner ring and solid cage (denoted by the suffix "EM") facilitates installation, debugging, and preload control, making it widely used in automotive gearboxes, precision machine tool spindles, construction machinery transmission systems, and other fields.

Core Parameters
Parameter Value
Inner diameter 40mm
Outer diameter 80mm
Width 18mm
Material Vacuum-degassed bearing steel (oxygen content ≤10ppm) with a hardness of HRC61-65
Service Life 25% longer than that of traditional bearings
Radial load capacity 62kN
Axial load capacity 7.2kN
Limiting speed 9500r/min (grease lubrication), 13000r/min (oil lubrication)
Precision grades P0 (general grade) and P6 (precision grade)
P6 grade details Raceway roundness error is ≤1.2μm, and the vibration value is reduced by 25%
Core Technologies and Manufacturing Processes

Material Innovation
Uses vacuum-degassed GCr15 bearing steel. Its microstructure is optimized through quenching + tempering processes, with wear resistance increased by 20% compared to ordinary electroslag steel. It is suitable for harsh environments such as high dust, strong impact, and a temperature range of -30℃ to 120℃.

Precision Design
Double-rib inner ring: Effectively restricts axial movement of rollers, improves the positioning accuracy of transmission systems, and adapts to the needs of high-precision equipment.
Solid cage (suffix "EM"): Optimizes the roller guidance trajectory, reduces friction loss by 18%, and significantly enhances stability during high-speed operation.

Applications in the Construction Machinery Field
  • Loader gearboxes: Widely used in loader transmission systems, it can stably withstand a radial load of 62kN with a failure rate of less than 0.7%.
  • Mining conveyors: Replaced NSK bearings in BHP Iron Ore's conveyors in Australia, reducing operation and maintenance costs by 28% and increasing wear resistance by 20%.
