Services - Troubleshooting - Damage by Load / Contact Patterns: As bearings rotate, the raceways of the inner ring and outer ring make contact with the rolling elements. This results in a wear path on both the rolling elements and raceways.
Services - Troubleshooting - Damage by Load / Contact Patterns: Typical Running Traces of Deep Groove Ball Bearings, showing the most common running trace generated when the inner ring rotates under a radial load only.

NSK Linear Actuator- multi-functional actuator designed with an all-in-one structure integrating a Ball Screw, Linear Guide, and support bearings to offer long-life & maintenance-free operation.
Troubleshooting - Linear Guides - Indentations: Dents on the raceway at each ball location similar to the deformation caused by a Brinell Hardness Test or on the raceway caused by contamination or metallic particles.
Services - Troubleshooting - Linear Guides - Fretting: Fretting is a type of wear that is caused by relative repeated rubbing with minute amplitude between contacting surfaces.
Services - Troubleshooting - Linear Guides - Damaged ball recirculation parts: Balls become free from the ball slide due to broken plastic ball re-circulation parts.
