Exact Fit
Matched the 6306 specs perfectly for my air compressor pump. Highly recommend checking the dimensions before ordering.

Perfect Replacement
Used this 6305 bearing for my lathe motor repair. It fit perfectly and runs very smoothly. No noise at all compared to the old one.

Smooth Operation
Very quiet after installation. I ordered the RS sealed version for my electric scooter wheel and it handles dust well.

Good Value
Works well for the price. The grease seems adequate. Shipping took a bit longer than expected but the product is solid.
Q: Do you offer bulk discounts for large orders?
A: Yes, we offer discounted pricing for bulk purchases. Please contact our sales team directly through the customer service portal for a quote.
Q: Can I use these for high-speed applications?
A: These are standard precision ABEC-1 bearings. They are suitable for general machinery but may not be ideal for extremely high-speed spindles requiring ABEC-5 or higher.
Q: Are these bearings made of stainless steel?
A: No, these are made of High Carbon Chrome Steel (GCr15) for durability and load capacity. They are coated with oil to prevent rust during storage.
Q: What is the warranty period for these bearings?
A: We offer a 30-day return policy for defective items. Industrial warranties may vary based on usage conditions and load specifications.
Q: What is the difference between ZZ and RS seals?
A: ZZ refers to metal shields on both sides, offering less friction but less protection. RS refers to rubber contact seals, offering better protection against dust and water but slightly higher friction.
