Lubrication of Linear Bearings

Understanding linear bearings, as well as the differences between them, is critical to ensure long-term, trouble-free performance in many different markets. Klüber Lubrication has prepared this explanation as a general guide. If a more detailed explanation is required, please contact your nearest Klüber Lubrication representative or the manufacturer of the lubricant you are using.

In this article we will cover the different types of linear bearings commonly used, types of friction and some of the lubrication solutions we could offer.

Overall, the main differences between a rolling element bearing and a linear bearing are:

• Linear bearings require far more lubricant than rotating bearings
• Mixed friction at the beginning and end of each stroke
• Lubricant is spread across the guide rail or spindle during motion
