Miniature Ball Screw Assembly Life

Never operate a ball screw assembly without proper lubrication. The lubricant maintains the low friction benefits of the ball screw assembly by reducing rolling resistance between the balls and grooves and sliding friction between adjacent balls. Oil can be applied in a controlled flow directly to where it is needed, and as the oil flows through the ball nut, it will sweep away contamination.

It can also provide cooling. On the other hand, a pump and metering system is required to apply the oil, since oil also has grease that contaminates the process fluid is less expensive than oil and does not require frequent use and does not contaminate the process fluid. Grease, on the other hand, is difficult to hold on to the ball nut and tends to build up at the end of the ball nut travel where debris and abrasive particles can build up. The incompatibility of old grease with regreasing can cause problems, so it is important to check compatibility.

The load bearing grease can help the life of the miniature ball screw assembly, but the overall load rating will not change. Controlling linear motion is a common requirement for equipment and laboratory equipment, and there are many linear drive options available. However, the nature of the laboratory application presented, for example, enables accurate, repeatable movements. Handle changing dynamic loads in increasingly smaller spaces; operate in clean environments requiring relatively little wear debris; and reduce instrument noise, vibration, and mechanical disturbances during operation.
