For use with Renewable SF Type Bushings

Round Clamps and Lock Screws are used in conjunction with the Slip Fixed renewable bushings and form part of a drilling assembly with the liners. The clamps and screws are used to lock the SF bushing in place.

Round Clamps

The clamps are slightly more robust than their lock screw counterpart; they can be fastened with a cap screw on the ‘fixed’ side of the bushing.

Lock Screws

These lock screws can be mounted on either side of the bushing, both the ‘fixed’ and ‘slip’ areas of the head. Lock screws are easy to use and are and economical choice for retaining the bushing.
