Product Description
CMT 791.016.00 Router Bit Bearing - 1 3/8" Diameter by CMT is a precision replacement guide bearing engineered for use with CMT router bits. Designed to fit flush trim, pattern, rabbeting, and profile bits, this steel bearing keeps your router guided accurately along template or workpiece edges for clean, repeatable cuts. Whether you are restoring worn-out guide bearings or upgrading an existing bit, this replacement bearing delivers the smooth rotation and dimensional accuracy that routing applications demand.
Key Features
- Steel construction - provides durability and resistance to the heat and friction generated during routing, extending the service life of the bearing in demanding applications.
- 1 3/8" outer diameter - matches the dimensional requirements of common CMT guide bearing positions, ensuring a proper fit and accurate edge-following on templates and workpieces.
- 4.76mm bore diameter - sized for compatibility with the shaft diameters found on CMT router bits, keeping the bearing securely centered for precise self-guiding performance.
- 11.5mm plate thickness - provides a stable bearing surface that maintains consistent contact with templates and guides, reducing wobble and improving cut quality.
- Black shield orientation matters - the black shield must be kept right side up to correspond with bearing rotation during reassembly, ensuring the bearing functions as intended after installation.
Why This Product
- A worn or damaged guide bearing can cause router bits to drift off template edges, resulting in inaccurate cuts - this direct replacement restores accurate self-guiding performance on flush trim, pattern, rabbeting, and profile bits.
- The specific 1 3/8" outer diameter and 4.76mm bore are matched to CMT router bit specifications, reducing the guesswork of finding a compatible replacement bearing.
- Steel construction means the bearing holds up to the rotational forces and heat of router table and handheld router use, giving you a reliable component rather than a short-lived substitute.
- With a plate thickness of 11.5mm, the bearing maintains a solid contact footprint against guides and templates, which translates directly to cleaner edges and more consistent profile depth across a workpiece.

Frequently Asked Questions
Does the orientation of the black shield matter when reassembling this bearing?
Yes - the black shield must be kept right side up to correspond with the bearing rotation during reassembly. Incorrect orientation can interfere with proper bearing function, so take note of the shield position before removal.
What types of router bits is this bearing designed to work with?
This bearing is used as a guide bearing on flush trim, pattern, rabbeting, and profile router bits. It serves as a replacement for worn or damaged bearings on CMT router bits that share these dimensional specifications.
What are the key dimensions of this bearing?
The bearing has a 1 3/8" outer diameter, a 4.76mm bore diameter, and a plate thickness of 11.5mm. Confirming these measurements against your existing bearing or bit specifications will help ensure a proper fit before installation.
Can this bearing be used on a router table as well as a handheld router?
Yes - this replacement guide bearing is compatible with both handheld router use and router table setups. Its steel construction is suited to the speeds and forces encountered in both operating environments.
