Reliable supplier
Third time ordering from this listing. Consistency is key for me and these bearings deliver every time. No issues with seals.

Smooth operation
Installed these in my robotics project. Noise levels are very low and they handle the speed well. Excellent Japanese engineering.

Good value
Bearings are good quality. Shipping took a bit longer than expected but the product itself is solid. Would buy again.

Genuine NSK Quality
Received the 6902ZZ bearings today. Packaging was secure and the markings on the bearing confirm authenticity. Smooth rotation right out of the box.

Perfect fit for my motor
I needed replacements for an older electric motor. These fit perfectly without any modification. Very happy with the purchase.
Q: Can I return these if the size is wrong?
A: Yes, provided the bearings are unused and in original packaging, you can initiate a return within our standard return window.
Q: Are these bearings genuine NSK products?
A: Yes, all our bearings are sourced directly from authorized distributors and are 100% genuine Japan NSK.
Q: Does the C3 clearance option affect performance?
A: C3 clearance is slightly larger than standard, allowing for higher speeds or thermal expansion. Choose based on your specific application needs.
Q: Is the bearing pre-lubricated?
A: Yes, these bearings come factory lubricated with high-quality grease suitable for general industrial use.
Q: What is the difference between ZZ and DDU seals?
A: ZZ refers to metal shields on both sides, while DDU indicates rubber contact seals on both sides for better protection against dust and moisture.
