Bearing races & rollers

Precision Steel Bars for Bearings

Bearing applications are susceptible to wear, leading to premature failures. Our cold drawn, turned, and centreless ground bright steel bars provide the durability needed to enhance reliability.

The wear problem

The primary wear mechanism in bearing races and rollers is sliding abrasion. This leads to surface degradation and eventual failure, often initiating at the contact points between rolling elements.

Selecting the right plate

Choose the right grade

Select grades based on the specific wear conditions and load requirements.

Consider thickness

Match thickness to the operational loads to optimize performance and wear life.

Assess surface finish

Ensure a high-quality surface finish to reduce friction and premature wear.

Review operating environment

Evaluate environmental conditions to choose grades with suitable corrosion resistance.

Questions engineers ask

What grade is best for high-load applications?

For high-load applications, 100Cr6 offers excellent fatigue strength and wear resistance. This grade is ideal for applications involving heavy rolling contact.

How does thickness affect wear performance?

Thicker bars provide enhanced strength and resistance to deformation. This can significantly improve wear life, especially in high-stress environments.

What is the importance of surface finish?

A superior surface finish minimizes friction, which is crucial for reducing wear in bearing applications. It also helps in preventing surface fatigue.

How do I select the right material grade?

Selecting the right material grade depends on load requirements, wear conditions, and environmental factors. Consult specifications to ensure compatibility.
