Perfect for my motor
Replaced old bearings in my electric motor with these HRB 6302 ZZ. They fit perfectly and run very smoothly. No noise at all.

Fast delivery
Item arrived well packaged in original boxes. One star off because I wished there was more grease included for maintenance.

Good value
Works as expected for the price. Shipping took a bit longer than anticipated but the product quality is solid.

Smooth operation
Very quiet running bearings. I used the 6305 model for a pulley system and it handles the load well.

Genuine HRB
Authentic packaging and markings. I have used Harbin bearings before and these match the quality I remember.
Q: Can I wash these bearings before use?
A: Not recommended. They come pre-lubricated from the factory. Washing them will remove the grease and reduce their lifespan.
Q: What type of grease is used inside?
A: They are filled with standard lithium-based grease suitable for general industrial applications and moderate temperatures.
Q: Are these metric or imperial sizes?
A: These are standard metric dimensions. Please refer to the specific model number chart for exact inner and outer diameter measurements.
Q: What is the difference between ZZ and RZ seals?
A: ZZ uses metal shields on both sides which allow higher speeds, while RZ uses rubber contact seals which offer better protection against dust and moisture.
Q: Do you ship each bearing individually?
A: Yes, each bearing is packaged in its original HRB branded box to ensure protection during transit.
