Genuine HRB Product

I was worried about fakes, but these are authentic. The laser marking is clear and the finish is excellent. Will buy again for my motor repair shop.

Excellent Quality for CNC

These HRB bearings are smooth and run quietly. I used the 6301 size for my CNC spindle upgrade and noticed less vibration immediately. Genuine product from the flagship store.

Perfect Fit for Lathe

Ordered the 6302 2Z for my old lathe. The dimensions were spot on and the P5 precision is noticeable. Shipping was fast and packaging prevented any damage.

Good but Tight

Quality seems high, but the 6303 felt a bit tight initially. After a short run-in period, it smoothed out nicely. Good value for the price compared to European brands.

5 FAQ

Q: Is P5 precision necessary for standard electric fans?

A: P5 is a high precision grade. For standard fans, P0 or P6 is usually sufficient, but P5 will provide quieter operation and longer life if budget allows.

Q: What is the bore size for the 6301 model?

A: The 6301 bearing has a bore size of 12mm, an outer diameter of 37mm, and a width of 12mm.

Q: What is the difference between 2Z and 2RZ seals?

A: 2Z refers to metal shields which allow higher speeds but less sealing. 2RZ refers to rubber contact seals which offer better protection against dust and moisture but have slightly higher friction.

Q: Do you offer bulk discounts for industrial orders?

A: Yes, please contact our customer service team directly through the store messaging system for quotes on bulk orders exceeding 50 units.

Q: Are these bearings genuine HRB products?

A: Yes, all bearings sold in this flagship store are 100% genuine HRB products with verification codes available on the packaging.
