Solid build quality

Feel robust and installation was standard. Took off one star because the packaging was a bit loose, but the bearings themselves are excellent.

Good value

Comparable to more expensive brands I have used in the past. Good choice for general motor maintenance tasks.

Corrosion resistance works

Used in damp environment for a water pump motor. After three months, there is no sign of rust. Very satisfied with the stainless steel quality.

Smooth spinning

No noise at high RPMs. I used these in a high-speed drill modification and they handle the speed well without overheating.

Great for e-bike conversion

Used the 6304 model for my hub motor rebuild. They fit perfectly and spin very smoothly. No noise even under load.

5 FAQ

Q: What is the main difference between 6301 and 6302?

A: The primary difference is the physical dimension. The 6302 has a larger outer diameter and width compared to the 6301. Please check your equipment specs.

Q: Which seal type is better for a dusty environment?

A: We recommend the RS (Rubber) seals for dusty environments as they provide better protection against contaminants compared to Z metal shields.

Q: Is the 440C stainless steel magnetic?

A: Yes, 440C stainless steel is magnetic, unlike some other austenitic stainless steels. This is normal for bearing grade stainless steel.

Q: Are these compatible with a 3000 RPM motor?

A: Yes, these bearings are rated for speeds well above 3000 RPM depending on the specific model and lubrication conditions.

Q: Do I need to add grease before installation?

A: No, the bearings come pre-lubricated with high-quality grease suitable for most standard applications.
