Perfect for Industrial Use
Ordered bulk for our factory maintenance team. The consistency across the 6300 series models is excellent. We will be ordering again.

Smooth Operation
Replaced old bearings with 6303 RS models in my home appliances. The rubber seals keep dust out effectively. Very satisfied with the performance.

Genuine LYC Quality
Received the 6305 ZZ bearings and they are definitely authentic. The packaging was secure and the bearings run smoothly without noise. Great for motor replacements.

Good but Packaging Could Be Better
Bearings are authentic and work well. One box arrived slightly dented, but the internal packaging protected the bearing. Product quality is top notch.
Q: Are these bearings pre-lubricated?
A: Yes, all units come pre-greased from the factory. They are ready for installation without additional lubrication for standard applications.
Q: Do you provide certification documents?
A: Yes, authenticity cards and quality inspection certificates are included with bulk orders. Please contact us directly for large quantity purchases.
Q: What is the maximum RPM?
A: Depends on specific size and lubrication. Generally, the 6300 series supports high speeds, but please refer to the technical datasheet for exact limits per model.
Q: What is the difference between RS and ZZ?
A: RS features rubber contact seals which offer better protection against moisture and dust. ZZ uses metal shields which allow for higher speeds but less sealing protection.
Q: Can I use these for electric motors?
A: Yes, the 6300 series is commonly used in electric motors. Please ensure you select the correct size and seal type for your specific motor model.
