Maintenance of Cross Roller Bearings
Cross roller bearings are the most versatile bearing design in the world today. They have a wide variety of uses including machine tools, precision instruments, medical equipment and robotics. To ensure your cross roller bearings are working efficiently and effectively, appropriate maintenance and inspection should be completed on a regular basis.
Inspection
The first step of cross roller bearing maintenance is inspection. This should include an evaluation of the condition of the ring and roller elements to detect any signs of contamination, damage or wear. It’s also important to check for correct installation and alignment as well as evidence of bearing misalignment caused by vibration or shock loading. High levels of contamination or wear in any component will require specialized repair or replacement.
Cleaning
Cross roller bearings should be kept free from dirt, dust, and other contaminants by regularly cleaning them. The best way to clean cross roller bearings is to blow off any dirt, dust or debris with compressed air. Additional cleaning can be done by wiping the outside of the bearing heads with a soft cloth and a mild detergent solution. Do not spray lubricant or solvents directly onto the bearing.
Lubrication
Regular lubrication helps to improve performance and extend the life of cross roller bearings. Appropriate lubrication for cross roller bearings includes oil or grease. Generally, oil is preferred for general duty, low to medium speeds, whereas grease is more suited to applications that involve higher speeds and temperature. Thicker grease should be used for bearings exposed to heavy loads and shock.
Storage
Storage conditions for cross roller bearings should always be kept clean and dry. Crossing roller bearings should ideally be stored in a cool, dry location, away from direct sunlight and away from potential sources of contamination. If bearings are to be stored for long periods, ensure they are always kept in an upright position and wrapped in a protective material.
Regular maintenance and inspection of cross roller bearings will help ensure optimal performance and a longer bearing life. Keep your bearings clean and lubricated appropriately and store them in a safe environment to ensure they remain in good condition. Following these simple maintenance procedures will help ensure you get the most out of your cross roller bearings.
