Product Description

Product Introduction

The rolling element is the core component of a rolling bearing; it is precisely because of its presence that rolling friction can occur between the surfaces in relative motion.

 

Technical Parameters

Diameter grouping: ≤0.002 mm;
Roundness: 1 μm;
Outer diameter surface roughness: Ra 0.06 μm;
Surface roughness: Ra 0.2 μm;
Hardness: 61–66 HRC.

 

Product Advantages

The needle rollers meet the G2 grade specified in GB/T309-2021, and the cylindrical rollers meet the G2 grade specified in GB/T4661-2015. They have successfully passed the wear test for a 1.6-million-kilometer maintenance-free universal joint.

 

Product Use

Needle roller products (needle roller bearings, needle rollers, etc.), due to their special structure and performance, are widely used in mechanical engineering in scenarios with high loads, compact controls and precision transmissions, and are often used in gearboxes and engines in the automotive industry; and machine tools and robots in industrial machinery.
