Good quality, slight noise initially
The bearings fit perfectly in my fishing reel. They were a bit stiff at first but loosened up after some use. Corrosion resistance is excellent.

Product is fine, packaging could be better
The bearings themselves work well and seem durable. However, one box arrived slightly dented. Fortunately, the parts inside were unaffected.

Great for food processing machine
We needed waterproof bearings for a washing station. These 304 steel bearings handle the moisture well and meet our hygiene standards.

Exactly as described
Ordered the S6204ZZ model. Dimensions were precise and the stainless steel feels high quality. Will order again for my machinery.

Perfect for marine equipment
Used these bearings on a boat trailer hub. After a season in saltwater, there is no rust whatsoever. Smooth rotation and great value.
Q: Do you offer bulk discounts for orders over 100 units?
A: Yes, we offer tiered pricing for bulk orders. Please reach out to our sales team via the contact form for a custom quote.
Q: Are these bearings pre-lubricated or do I need to add oil?
A: All our stainless steel bearings come pre-lubricated with high-grade grease suitable for general purposes. You can add more lubrication if needed for specific applications.
Q: What is the main difference between 440 and 304 stainless steel bearings?
A: 440C stainless steel is harder and offers better wear resistance, while 304 stainless steel provides superior corrosion resistance in harsh chemical environments.
Q: Is the ZZ seal completely waterproof?
A: ZZ metal shields offer protection against dust and some moisture, but for full waterproofing in submerged conditions, we recommend the 2RS rubber seal variant.
Q: Can I use these in high-temperature applications above 150°C?
A: No, the standard grease and steel formulation are rated up to 120°C. For higher temperatures, please contact us for specialized high-heat bearing options.
