Perfect Fit for Motor Assembly
Ordered the 6212-2Z bearings for a motor repair project. The dimensions were exact and the rotation is incredibly smooth. Genuine HRB quality as expected.

Smooth Operation Under Load
Replaced old worn-out bearings with these 6213 models. The machine runs much quieter now and there is no excessive heat generation.

Good Quality, Slow Shipping
The bearings themselves are excellent and handle heavy loads without noise. Only giving 4 stars because delivery took a bit longer than estimated.
Q: What is the difference between 2Z and 2RZ seals?
A: 2Z refers to metal shields on both sides which allow higher speeds, while 2RZ indicates non-contact rubber seals that offer better protection against dust and moisture.
Q: How do I claim warranty if a bearing fails?
A: Please contact our support with your order number and photos of the defect. We offer a 12-month warranty against manufacturing defects.
Q: Can these handle high RPM applications?
A: They are designed for standard industrial speeds. For very high-speed applications, please consult our technical team for specific limiting speed ratings.
Q: What are the exact dimensions for the 6210 model?
A: The 6210 bearing has an inner diameter of 50mm, an outer diameter of 90mm, and a width of 20mm.
Q: Are these bearings pre-lubricated?
A: Yes, all HRB deep groove ball bearings come pre-lubricated with standard grease suitable for general industrial applications.
