Glossary

Friction is the force that occurs between the contact surfaces of rolling elements and raceways in a rolling bearing. It opposes the momentum of motion and generates resistance, which can affect the performance and efficiency of the bearing.

• Question: How can friction be measured or quantified?
  • Answer: Friction can be measured using various methods, including the use of torque measuring devices. These devices can be used to capture and quantify the frictional losses in a rolling bearing. The measured torques allow for an assessment of the bearing's frictional characteristics.

• Question: What components influence friction in rolling bearings?
  • Answer: Various components in a rolling bearing can influence friction. These include the lubricant used (e.g., grease), seals, and the cage. Choosing the right lubricant and optimal sealing can reduce friction and improve the efficiency of the bearing.

• Question: Why is reducing friction in rolling bearings important?
  • Answer: Reducing friction is important because it directly affects the performance and efficiency of a bearing. Lower friction leads to less energy loss and reduced wear, which can extend the bearing's service life. This is especially crucial in applications with high speeds and precision requirements.
