Brinelling Bearing: A Comprehensive Guide to Cause, Prevention, and Mitigation

Brinelling bearing is a common problem that can occur in rolling element bearings. It is caused by a static load being applied to the bearing, which causes the balls or rollers to indent the raceway. This can lead to premature bearing failure.

Causes of Brinelling Bearing

The most common cause of brinelling bearing is improper handling or storage. When a bearing is subjected to a static load, the balls or rollers will deform and create indentations in the raceway. This can happen if the bearing is dropped, improperly installed, or stored in a way that allows a static load to be applied.

Effects of Brinelling Bearing

Brinelling bearing can have a number of negative effects on the bearing, including:

• Reduced bearing life
• Increased vibration
• Noise
• Premature failure

Prevention of Brinelling Bearing

There are a number of steps that can be taken to prevent brinelling bearing, including:

• Properly handling and storing bearings
• Using bearing isolators
• Applying a preload to the bearing
• Choosing the right bearing for the application

Mitigation of Brinelling Bearing

If brinelling bearing does occur, there are a number of steps that can be taken to mitigate its effects, including:

• Removing the static load from the bearing
• Regrinding the raceway
• Replacing the bearing

Stories

Story 1:

A maintenance technician was inspecting a bearing on a conveyor belt. He noticed that the bearing was making a noise. He removed the bearing and inspected it more closely. He found that the bearing was brinelled. The technician determined that the brinelling was caused by a static load that had been applied to the bearing. The technician replaced the bearing and applied a preload to the new bearing to prevent brinelling from occurring again.

Story 2:

A quality inspector was inspecting a batch of bearings. He found that several of the bearings were brinelled. The inspector rejected the bearings and sent them back to the manufacturer. The manufacturer determined that the brinelling was caused by improper handling. The manufacturer repackaged the bearings and sent them back to the customer.

Story 3:

A design engineer was designing a new machine. He specified a bearing that was resistant to brinelling. The engineer chose a bearing that was made of a hardened steel and had a high load capacity. The engineer also specified that the bearing be preloaded. The machine was built and tested. The bearing performed well and did not show any signs of brinelling.

Pros and Cons of Brinelling Bearing

Pros:

• Reduced friction
• Increased load capacity
• Improved wear resistance

Cons:

• Increased noise
• Reduced speed capability
• More expensive

FAQs

1. What is brinelling bearing?

Brinelling bearing is a condition in which the balls or rollers of a bearing indent the raceway. This can lead to premature bearing failure.

2. What are the causes of brinelling bearing?

The most common cause of brinelling bearing is improper handling or storage. Other causes include impact loading and excessive vibration.

3. What are the effects of brinelling bearing?

Brinelling bearing can reduce bearing life, increase vibration, cause noise, and lead to premature bearing failure.

4. How can brinelling bearing be prevented?

Brinelling bearing can be prevented by properly handling and storing bearings, using bearing isolators, applying a preload to the bearing, and choosing the right bearing for the application.

5. How can brinelling bearing be mitigated?

If brinelling bearing does occur, it can be mitigated by removing the static load from the bearing, regrinding the raceway, or replacing the bearing.

6. What are the pros and cons of brinelling bearing?

The pros of brinelling bearing include reduced friction, increased load capacity, and improved wear resistance. The cons of brinelling bearing include increased noise, reduced speed capability, and higher cost.
