Ball screw bearings can be used in a wide range of manufacturing machinery, but they are most commonly employed in machine tools to achieve specific production objectives. During operation, the ball circulation modes may include recirculating‑tube type, recirculator type, and end‑cap type. As for preload methods, the primary approaches are positioning preload and constant‑force preload.
During operation, it is essential to select the appropriate type based on the intended application. Ball screws are available in a high‑precision ground‑machined version, with accuracy levels ranging from CO to C7. Another option is ball screw assemblies produced via high‑precision cold rolling, which achieve accuracy grades from C7 to C10. Choose the ball screw that best suits your needs by selecting from these precision grades.
Because ball screws operate continuously during use, they are subject to significant wear; therefore, maintaining proper lubrication is crucial. To achieve adequate lubrication, a lubricant must be applied. Two common types of lubricants used on ball screws are lubricating oil and grease.
Lubricating oil can include engine oil, as well as turbine oil grades 90 to 180; some ball screws also use spindle oil grade 140. For lubricating grease, lithium-based grease is a suitable choice; however, when applying grease, it should be applied to the thread raceways and within the housing space where the nut is mounted.
