Ball bearing screw lubrication reduces friction, wear, and heat buildup, ensuring smooth and efficient motion. Proper lubrication extends service life and maintains accuracy in CNC machines, robotics, and automation systems. Lubricants can be oil or grease, depending on speed, load, and operating conditions. Automatic lubrication systems provide continuous application, while manual lubrication requires regular maintenance. Choosing the right lubricant minimizes backlash, prevents contamination, and improves overall performance in high-precision and high-load applications.
