SHIM ADJUSTABLE COMBINED ROLLER BEARINGS
These combined bearings are adjustable by introducing shims between the hub and the
axial roller carrier. This enables the overall height of the bearing to be altered.
Use in conjunction with the steel profiles (rails) to make a heavy duty sliding system - see table for corresponding profiles.
*4.080 is also available with a plastic axial rubbing block - part number 4.080P.
