Great for CNC build

Used KH2030 on my X-axis. Very smooth movement and the seals keep dust out.

Solid bearings

Works well but shipping packaging could be better. One box was slightly dented.

Precise fitment

Measured the inner diameter and it matches standard shafts perfectly. Good quality steel.

5 FAQ

A: The PP seals are pressed in and not designed for replacement by end users.

Q: Do you offer bulk discounts for large orders?

A: Yes, please contact our sales team for orders over 50 units for pricing options.

Q: What shaft tolerance is required for these bearings?

A: We recommend h6 or g6 shaft tolerance for optimal performance and longevity.

Q: Is the pre-applied grease food grade safe?

A: No, this is standard industrial grease. Not suitable for food processing machinery.
