Precise dimensions
Measured every bearing in the pack with calipers. All within tolerance. Smooth rotation out of the box. Great for precision machinery.

Excellent for saltwater use
Replaced all the bearings on my boat trailer with these. After a full season of saltwater exposure, there is zero rust. Highly recommend for marine applications.

Durable and reliable
Using these in a high vibration environment. They have held up well without loosening or failing. The 440 steel provides good hardness.

Perfect fit for 6902 size
Bought specifically for the 6902 model. Fit perfectly into my electric scooter wheel hub. Much better than the carbon steel ones I had before.

Good quality, slow shipping
The bearings themselves are fantastic and spin very quietly. Only giving 4 stars because the shipping took longer than expected. Product quality is 5 stars though.
Q: Is the grease food grade safe?
A: The standard lubrication is industrial grade. If you require food grade grease for FDA compliant applications, please specify this in your order notes.
Q: Do you offer bulk discounts for over 100 units?
A: Yes, please contact our sales team directly through the customer service portal for bulk pricing inquiries on orders exceeding 100 units.
Q: Are these bearings sealed on both sides?
A: Yes, all bearings in this series come with shields or seals on both sides to protect the internal components from dust and debris.
Q: What is the main difference between the 440 and 304 steel options?
A: 440C stainless steel is harder and offers better wear resistance for high load applications, while 304 stainless steel offers superior corrosion resistance in harsh chemical environments.
Q: Can these handle high temperatures?
A: Standard grease lubrication allows operation up to 120°C. For higher temperatures, special high-heat grease may be required.
