> 3 dayThese are supposed to be .250 internal dimension ( ID) bearings, but measure .246-.247 A 1/4 shaft will not fit. The OD is very good and within spec.

15-06-2025I do a lot of template routing. I have a Whiteside hinge mortise bit that I mostly use for relief-sculpture-style stock removal. The carbide is excellent, but the process eats bearings. These are great, affordable replacements.

Deep Groove Ball Bearings
- Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions (Mainly bear radial load, but also can bear a certain amount of axial load).
- With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
- Suitable for all kinds of industrial equipment, motor, roller wheels, office equipment and so on.
- Note: Please confirm the size and type of ball bearing before ordering.
Selecting Guide:
- Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
- Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
- Single-row
- Pre-lubricated
- Normal accuracy
