Carr Lane Manufacturing · Quick Ship in Stock
Head liners with a sturdy built-in locking tab that removes the need for a lockscrew. UL liners hold SF renewable bushings on the slip side and cut installation time dramatically.
Genuine Carr Lane parts. Equivalent ADB, Boneham and ACTEK bushings quoted on request.

Length is overall length, not including the locking tab. Other sizes and materials are available by special order.
A UL liner costs slightly more than a head liner plus a lockscrew, but there is no tapped hole to drill and no lockscrew to install, so installation time is dramatically reduced.
For cast or potted tooling, ask about diamond-knurl Un-A-Lok liners (ULD) and EZ-Cast liners from our castable bushings line.
No. Un-A-Lok liners hold SF renewable bushings on the slip side only. Use a standard liner and lockscrew if you need the fixed side.
Quick-Ship sizes are the most popular Carr Lane drill bushings, kept in stock at the St. Louis warehouse and ready for same-day shipment. Other sizes in the same series are made to order with a longer lead time.
Yes. Send the Carr Lane part number or your print and we will quote the matching ADB, Boneham or ACTEK bushing alongside the Carr Lane part, so you can compare price and lead time.
