Product Description
CMT Bearing 13mm - 5mm is a precision steel replacement bearing designed to restore smooth, accurate self-guiding performance to CMT router bits. Whether you are refitting a flush trim bit, a pattern bit, a rabbeting bit, or a profile bit, this guide bearing keeps your router tracking cleanly along templates and workpiece edges - delivering consistent results on routers and router tables alike. The 13mm outer diameter and 5mm bore are matched to specific CMT bit configurations, making this a straightforward, exact-fit replacement for worn or damaged bearings.
Key Features
- Steel construction - provides the durability and rigidity needed to withstand the continuous rotational forces generated during routing, helping the bearing maintain its shape and precision over extended use.
- 13mm outer diameter with a 5mm bore - these precise dimensions ensure a correct, snug fit on compatible CMT router bit shanks, eliminating wobble and keeping cuts accurate and repeatable.
- 4mm plate thickness - a compact profile that fits within the tight clearances of router bit assemblies without interfering with cutting geometry or depth of cut.
- Black shield orientation requirement - the bearing must be reassembled with the black shield facing the correct direction to correspond with bearing rotation, ensuring the internal components function as intended and the bearing seats properly.
Why This Product
- Restores reliable self-guiding to flush trim, pattern, rabbeting, and profile router bits - rather than replacing an entire bit, swapping a worn bearing brings the tool back to full working condition at a fraction of the cost.
- The exact 13mm x 5mm x 4mm dimensions are purpose-matched to specific CMT router bit configurations, so there is no guesswork about fitment when ordering a direct replacement.
- Steel construction means the bearing holds up to the heat and friction of repeated routing passes, making it a practical long-term solution for both hobby and production routing environments.
- Compatibility with both handheld routers and router tables gives this bearing broad utility across different workshop setups, whether you guide by hand or use a fence-free table routing method.

Frequently Asked Questions
What router bit types is this bearing compatible with?
This bearing is used as a guide bearing on flush trim bits, pattern bits, rabbeting bits, and profile bits. It is a replacement bearing intended for CMT router bit configurations that accept a 13mm outer diameter bearing with a 5mm bore.
Is there anything important to know when reassembling the bearing onto a router bit?
Yes - the black shield on the bearing must be kept right side up and oriented to correspond with the direction of bearing rotation during reassembly. Incorrect orientation can affect how the bearing seats and functions.
What machines can I use this bearing replacement with?
This guide bearing is suitable for use with both handheld routers and router tables, wherever the compatible CMT router bits are used.
What are the exact dimensions of this bearing?
The bearing has a 13mm outer diameter, a 5mm bore diameter, and a 4mm plate thickness. These dimensions are specific to compatible CMT router bit models and should be verified against your existing bearing before ordering.
