Check your shaft size

Works great but make sure you measure your shaft diameter accurately before ordering. The SDM series is precise.

Good quality but shipping slow

The bearings themselves are excellent and fit perfectly. Only downside was the import shipping took a bit longer than expected.

Genuine EASE product

Very quiet compared to cheap alternatives. The double seals keep dust out effectively which is crucial for my workshop environment.

Perfect fit for CNC router

These bearings slide smoothly on the hardened shafts. Genuine EASE quality made a noticeable difference in vibration reduction.
