Tips for selecting and applying telescoping linear

Profiled rail and round shaft linear bearings are ideal for applications that require long stroke lengths in a fixed footprint But if the design calls for a bearing that can retract to move away from the process or to allow access to a working area a fixed rail or shaft won't do

The Choice of QIBR Bearing Grease or Oil

The Choice of QIBR Bearing Grease or Oil Posted by bella on July 19th 2020 QIBR bearings have both rolling and sliding friction Sliding friction is caused by the deviation of the rolling bearing on the surface curve and the deformation of the bearing under load

Care and Maintenance of Bearings

2020-3-18The rolling-contact bearing is an element of machinery with a very important role and is critical to the performance of the machine If one of the bearings breaks or seizes not only the machine but also the assembly line may stop If one of the axle bearings of an automobile or a railway car breaks down a serious accident could occur

Bearing Engineering and Knowledge Application

A bearing is a machine element that constrains relative motion and reduces friction between moving parts to only the desired motion The design of the bearing may for example provide for free linear movement of the moving part or for free rotation around a fixed axis or it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts
