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.
Q: What is the difference between SDM and SDMUU?
A: The UU designation indicates double rubber seals on both ends. Standard SDM may be open or single sealed depending on specific sub-model.
Q: What shaft tolerance is recommended for these bearings?
A: We recommend using hardened ground shafts with h5 or h6 tolerance for optimal performance and lifespan.
Q: Are these bearings pre-lubricated?
A: Yes, all EASE SDM series bearings come pre-lubricated with high-quality grease from the factory.
Q: Can these be used in high temperature environments?
A: Standard grease is rated up to 80 degrees Celsius. For higher temperatures, special lubrication may be required.
Q: Do you offer bulk discounts for industrial orders?
A: Yes, please contact our sales team directly through the customer service page for volume pricing on large quantities.
