Perfect replacement
Fit my 6305 housing perfectly. Much better than the chrome steel ones I used before in this environment.

Good value
Quality is solid though shipping was slow. The bearings themselves perform well under moderate load.

Excellent corrosion resistance
Used these in a high humidity workshop and they show no signs of rust after several months. Smooth operation.

Smooth rotation
Very quiet operation under load. I appreciate the metal shields keeping the grease in.

Durable construction
No signs of rust after 3 months of use in a marine application. Highly recommend for wet areas.
Q: Is additional greasing required?
A: They come pre-greased from the factory. You can add more later if needed through the shield gap carefully.
Q: What is the inner diameter of 6304?
A: The 6304 model has a 20mm bore inner diameter, 52mm outer diameter, and 15mm width.
Q: Is the 6306ZZ fully sealed?
A: It features metal shields on both sides, which protects against dust but is not waterproof for submersion.
Q: Do you offer bulk discounts?
A: Yes, please contact our support team directly for pricing on orders larger than 50 units.
Q: Can these handle high speeds?
A: They are suitable for moderate speeds typical of the 6300 series. For very high RPM, ceramic hybrids are recommended.
