Product Description
CMT Delrin Triangular Bearing - 1/2" Diameter, 3/16" Bore is a precision replacement bearing engineered specifically for solid surface router bits. This Delrin triangular bearing provides smooth, consistent guidance when used with flush trim, pattern, and profile routing applications, helping woodworkers and fabricators achieve clean, accurate results along templates and workpiece edges. The triangular design and Delrin construction make this bearing a reliable choice for maintaining control and performance during solid surface routing tasks.
Key Features
- Delrin bearing construction for solid surface router bits - the Delrin material is specifically suited to solid surface routing, reducing friction and wear for smoother guided cuts on demanding materials.
- 1/2" outer diameter - sized to fit a wide range of CMT router bit assemblies, ensuring proper alignment and consistent edge following without slipping or wobbling.
- 4.76mm bore diameter - a precise bore size that fits the pilot pin securely, maintaining tight tolerances for accurate, repeatable guided routing performance.
- 5.8mm plate thickness - provides structural stability within the bit assembly, keeping the bearing seated correctly and contributing to consistent cutting depth and edge quality.
- Black shield orientation - reassemble with the black shield right side up to correspond with the correct bearing rotation direction, helping preserve bearing function and longevity after servicing or replacement.
Why This Product
- Designed specifically for solid surface router bit applications, this Delrin triangular bearing addresses the guidance and wear requirements that standard bearings may not meet in solid surface work.
- The precise 4.76mm bore and 1/2" outer diameter specifications ensure a proper fit in compatible CMT router bit assemblies, minimizing play and maintaining guided cut accuracy.
- Replacing a worn or damaged bearing with this exact-specification part restores bit performance without requiring full bit replacement, making it a cost-effective maintenance solution.
- The clearly marked black shield and directional reassembly guidance help ensure the bearing is reinstalled correctly, reducing the risk of premature failure after servicing.

Frequently Asked Questions
What type of router bits is this bearing designed for?
This Delrin triangular bearing is designed specifically for solid surface router bits. It functions as a guide bearing to help the bit follow a template or workpiece edge during routing operations.
What does "Delrin" mean in the context of this bearing, and why does it matter?
Delrin refers to the bearing material used in this product. For solid surface routing applications, this material provides the friction and wear characteristics needed for smooth, guided performance - making it the correct replacement choice for compatible solid surface router bits rather than a standard steel bearing.
Is there a specific orientation I need to follow when reinstalling this bearing?
Yes. When reassembling, keep the black shield right side up so that it corresponds with the correct bearing rotation direction. This is important for maintaining proper bearing function and avoiding premature wear after a bearing replacement.
What are the key dimensions of this bearing?
The bearing has a 1/2" outer diameter, a 4.76mm bore diameter, and a plate thickness of 5.8mm. Always verify these dimensions match the requirements of your specific CMT router bit before installing a replacement bearing.
