Product Description
CMT Bearing 22mm - 8mm is a precision replacement bearing designed to keep your CMT router bits running true and smooth. Built for use as a guide bearing on flush trim, pattern, rabbeting, and profile router bits, this steel bearing delivers reliable edge-following performance on both routers and router tables. Whether you are restoring a worn-out bit to like-new performance or upgrading your setup for tighter tolerances, this guide bearing is the direct-fit solution engineered for CMT tooling.
Key Features
- Steel construction - provides durability and resistance to the mechanical stress of repeated router bit use, helping the bearing hold up through demanding production and workshop applications.
- 22mm outer diameter with 8mm bore - matches the geometry of compatible CMT router bits precisely, ensuring accurate, wobble-free guidance along template or workpiece edges without the need for modification.
- 6mm plate thickness - gives the bearing a solid, stable profile that maintains consistent contact with the guide surface throughout the cut.
- Black shield orientation matters during reassembly - the black shield must be kept right side up to correspond with bearing rotation, ensuring proper sealing and long bearing life after installation.
Why This Product
- A worn or failed guide bearing causes inconsistent edge profiles and can damage workpieces - replacing it with this direct-fit CMT bearing restores accuracy and protects your investment in quality router bits.
- With a 22mm outer diameter and 8mm bore, this bearing is spec-matched to CMT router bit dimensions, so there is no guesswork about fitment on flush trim, pattern, rabbeting, or profile bits.
- Steel construction means this bearing can handle the rotational forces and heat generated during extended routing sessions, making it suitable for both shop use and repetitive production runs.
- Keeping the correct shield orientation during reassembly - as noted in the product guidance - ensures the bearing functions as intended, protecting against premature wear and maintaining smooth self-guiding performance.

Frequently Asked Questions
What router bit types is this bearing compatible with?
This bearing is used as a guide bearing on flush trim, pattern, rabbeting, and profile CMT router bits. It is intended as a direct replacement for worn or damaged bearings on those bit styles.
What are the key dimensions of this bearing?
The bearing has a 22mm outer diameter, an 8mm bore diameter, and a 6mm plate thickness. These measurements are important to verify against your existing bearing before installing.
Is there anything important to know when reassembling this bearing onto a router bit?
Yes - the black shield must be kept right side up to correspond with the bearing rotation during reassembly. Incorrect orientation can affect the bearing seal and reduce its service life.
What is this bearing made of?
This bearing is made of steel, which provides the strength and durability needed to withstand the rotational forces and heat generated during routing operations on both handheld routers and router tables.
