Great corrosion resistance
Used in a humid environment with no rust appearing after several months. Exactly what I needed for outdoor equipment.

Good quality bearings
Slightly tighter fit than expected but works well after break-in period. Material feels solid and durable.

Perfect for drone motors
Smooth operation and light weight. These bearings fit perfectly into my custom drone build and spin freely without noise.
Q: Can I relubricate them after use?
A: No, ZZ shields are non-removable. They are pre-lubricated for maintenance-free operation.
Q: What is the maximum RPM for these bearings?
A: Depends on lubrication and load, generally up to 30,000 RPM for miniature sizes under light load.
Q: What is the warranty period?
A: We offer a 1-year manufacturer defect warranty covering material and workmanship issues.
Q: Do you offer bulk pricing for large orders?
A: Yes, contact us directly for orders over 100 packs to discuss volume discounts.
Q: Are these bearings magnetic?
A: Stainless steel is generally low magnetic permeability, but slight magnetism may occur due to manufacturing processes.
