Smooth running
Very quiet operation on my lathe spindle. I appreciate the pre-lubricated grease saving me time during installation. Highly recommend for hobbyists.

Good but tight fit
Quality is excellent, but the 6305 2Z required a bit more force to install than expected. Once seated, it works great. Just ensure you have the right tools.

Reliable industrial grade
Using these in our production line conveyor system. We ordered a bulk pack and quality seems consistent across all units. Good value for money.

Perfect fit for my motor
Replaced old bearings on my industrial motor with these HRB 6307 units. They fit perfectly and run very smoothly. No excessive noise or vibration.

Authentic product
I was worried about counterfeits but these are genuine HRB bearings. Packaging was secure and labels matched the official specifications.
Q: Do you ship these individually or in bulk?
A: Each bearing is packaged individually in its original HRB box. Bulk orders are shipped in larger cartons containing multiple boxes.
Q: Is the pre-installed grease suitable for high temperatures?
A: The standard grease is suitable for operating temperatures up to 120 degrees Celsius. For higher temps, special lubrication may be required.
Q: What is the difference between 2Z and 2RZ seals?
A: 2Z indicates metal shields on both sides, while 2RZ indicates rubber contact seals on both sides. 2RZ offers better protection against dust and moisture.
Q: What is the inner diameter of the 6305 bearing?
A: The 6305 bearing has an inner diameter (bore) of 25mm, an outer diameter of 62mm, and a width of 17mm.
Q: What is the maximum RPM for the 6308 model?
A: The reference speed for a 6308 bearing is approximately 8500 rpm, though this varies based on lubrication and load conditions.
