Product Description
CMT 791.026.00 Bearing 28mm - 12mm by CMT is a precision replacement guide bearing designed to restore smooth, accurate self-guiding performance to CMT router bits. With a 28mm outer diameter and a 12mm bore, this steel bearing fits flush trim bits, pattern bits, rabbeting bits, and profile bits - keeping cuts guided cleanly along templates or workpiece edges. Whether you are replacing a worn bearing or upgrading an existing setup, this bearing is built to maintain consistent contact and rotation during routing operations.
Key Features
- Steel construction - provides the durability and rigidity needed to withstand the rotational forces and friction generated during continuous router bit guiding.
- 28mm outer diameter - determines the cutting offset from your template or workpiece edge, giving you precise control over how much material the bit removes.
- 12mm bore diameter - fits the shank or pilot post of compatible CMT router bits, ensuring a secure, centered fit that eliminates wobble during cutting.
- 8mm plate thickness - provides the structural depth needed for stable, even contact against the guiding surface throughout the full cut.
- Black shield orientation must be maintained during reassembly - the shield is directional relative to bearing rotation, so correct reassembly protects internal components and ensures long-term bearing life.
Why This Product
- Designed specifically as a replacement and upgrade bearing for CMT router bits - so you get a dimensionally correct fit without guessing at compatibility or making modifications.
- The 28mm outer diameter and 12mm bore combination makes this bearing a direct match for flush trim, pattern, rabbeting, and profile bit applications where guide bearing size directly affects cut accuracy.
- Steel construction means the bearing handles the heat and mechanical stress of routing without deforming, keeping your guided cuts accurate pass after pass.
- Replacing a worn guide bearing with this part restores the original cutting geometry of your router bit, extending the useful life of the bit itself and avoiding the tear-out and drift that a failing bearing causes.

Frequently Asked Questions
What router bit types is this bearing compatible with?
This bearing is designed for use with CMT router bits that use guide bearings, including flush trim bits, pattern bits, rabbeting bits, and profile bits. Verify that your specific bit uses a 28mm outer diameter and 12mm bore before installing.
Does the orientation of the bearing matter during reassembly?
Yes - the black shield on the bearing must be kept right side up to correspond with the bearing's rotation direction during reassembly. Installing the shield in the wrong orientation can compromise bearing performance and longevity.
What is the plate thickness of this bearing, and why does it matter?
The plate thickness is 8mm. This measurement determines how much axial depth the bearing occupies on the bit's pilot post, which affects how the bearing seats and contacts the guiding surface during a cut. Using a bearing with the correct thickness ensures stable, flush contact.
What material is this bearing made from?
This bearing is made of steel, which provides the strength and heat resistance needed to handle the rotational forces and friction involved in router bit guiding applications.
