Clearance and Fit of The Linear Bearings

When a standard-type MCS linear bearing is used with a shaft, inadequate clearance adjustment may cause early bush failure and/or poor, rough travelling. The clearance adjustable linear bearing and open linear bearing can be clearance adjusted when assembled in the housing which can control the outside cylinder diameter. However, too much clearance adjustment increases the deformation of the outside cylinder, to affect its precision and life. Therefore, the appropriate clearance between the linear bearing and the shaft, and clearance between the linear bearing and housing are required according to the application. Below table shows recommended fit of the linear bearing.
