Our S688-ZZ Thin Section Stainless Steel Bearings are engineered for applications where space is premium and weight reduction is critical. Made from high-grade AISI 440C stainless steel, these miniature bearings offer excellent corrosion resistance while maintaining high running accuracy and low friction torque.

Key Features:

Space & Weight Saving: Extremely thin cross-section allows for compact machine designs and reduces overall system weight.

Premium Material: Manufactured from high-quality AISI 440C stainless steel (or AISI 304/316 upon request) for superior rust and corrosion protection.

High Precision & Low Noise: Pre-lubricated with premium grease to ensure smooth, quiet operation at high speeds.

Dual Metal Shields (-ZZ): Protects the internal balls from dust, dirt, and contaminants while retaining lubrication.

Typical Applications:

Drones & UAVs (Unmanned Aerial Vehicles)

Robotic Joints & Precision Automation Grippers

Medical Instruments & Dental Equipment

Optical Encoders & Stepper Motors
