The right choice of oil or grease for ball screws reduces unscheduled downtime and repairs by ensuring the assemblies deliver their expected service lives. The author, Jeff Johnson, uses the correct lubrication method to apply Thomsonâs Linear Lube to a ball screw. One of the first choices engineers must make is whether to use oil or grease. Proper selection and application of lubricants also affects contamination, a leading cause of premature ball-screw failure. Lubricant reduces the already low friction by minimizing contact between the balls and grooves, thus adding torque and increasing efficiency, while extending the screw’s life by a factor of 10. Lubricants on ball screws are as important to their performance and life as are their operating loads, speeds, accuracies, environments, and power requirements. ![]() This file type includes high-resolution graphics and schematics when applicable.
