Product Description
The CMT 791.014.00 Bearing 1-1/8" - 3/16" is a precision replacement router bit bearing designed to restore smooth, accurate self-guiding performance to flush trim, pattern, rabbeting, and profile router bits. Built from steel, this guide bearing fits CMT router bits and delivers reliable edge-following performance when used on a router or router table. Whether you are replacing a worn bearing on a rabbeting bit or upgrading the guide on a flush trim bit, this CMT replacement bearing keeps your cuts on track and your profiles consistent.
Key Features
- Steel construction - provides the durability and rigidity needed to withstand repeated routing passes and maintain accurate guidance along templates or workpiece edges.
- 1 1/8" outer diameter - matches the correct bearing size for compatible CMT router bits, ensuring proper fit and consistent edge contact without modification.
- 4.76mm bore diameter - sized to seat correctly on the bit shank, preventing wobble and keeping the bearing centered for straight, clean cuts.
- 8.4mm plate thickness - provides the right depth of contact surface so the bearing rides smoothly against templates and workpiece edges without tipping or skipping.
- Black shield orientation matters - the black shield must be kept right side up to correspond with bearing rotation during reassembly, ensuring the bearing performs correctly after installation and preventing premature wear.
Why This Product
- A worn or damaged guide bearing causes router bits to wander off the template or workpiece edge - replacing it with this precision steel bearing restores accurate, repeatable cuts without replacing the entire bit.
- The exact 1 1/8" outer diameter and 4.76mm bore are matched specifications for compatible CMT router bits, so there is no guesswork about fit when swapping out a guide bearing on flush trim, pattern, or profile bits.
- At 8.4mm plate thickness, the bearing offers a stable contact surface against templates and edges, which translates to smoother router travel and cleaner finished profiles.
- Rebuilding a quality router bit with a fresh replacement bearing is a cost-effective way to maintain a full set of working bits - this bearing is the direct replacement component for that job.

Frequently Asked Questions
What types of router bits is this bearing used with?
This bearing is used as a guide bearing on CMT router bits including flush trim, pattern, rabbeting, and profile bits. It is the correct replacement when the existing bearing on one of those bit types is worn or damaged.
Is there a specific way to install the bearing during reassembly?
Yes. The black shield must be kept right side up to correspond with the bearing rotation during reassembly. Reversing the shield orientation can result in incorrect bearing performance, so confirm the shield direction before reinstalling.
What machines can this bearing be used with?
This replacement bearing is compatible with routers and router tables. It is intended for use with CMT router bits mounted in either a handheld router or a router table setup.
What are the key dimensions I should verify before ordering this bearing?
The three dimensions to confirm are the outer diameter (1 1/8"), the bore diameter (4.76mm), and the plate thickness (8.4mm). Matching all three dimensions to your existing bearing ensures a proper fit on the router bit.
