High Performance 685Z Miniature Bearing

Precision-engineered deep groove ball bearing with dimensions 5x11x5mm for smooth rotation under high-speed conditions. Features durable chrome steel construction for extended lifespan and 2RS/ZZ shielding options for dust and debris protection. Ideal for miniature motors, medical devices, RC models, and precision instruments.

Ultra-Smooth Operation

Polished raceways and grade-10 steel balls minimize friction, ensuring quiet performance at 20,000+ RPM. Zinc-plated shields prevent lubrication leakage while maintaining low torque resistance.

Versatile Industrial Applications

Perfect for drone gimbals, CNC spindle auxiliaries, optical equipment, and small appliance mechanisms. Sealed variants (685-2RS) suit humid environments; open design (685Z) allows custom lubrication.

Bulk Purchase Advantage

Wholesale pricing available for OEMs and repair workshops. Compatible with international standards (ABEC-1), shipped in anti-rust packaging. Stocked in bulk for immediate dispatch.

Note: Specify required shield type (ZZ metal or 2RS rubber) when ordering.
