6811zz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile ensures smooth ball movement and efficient radial load distribution, contributing to the bearing's 1980 lbf dynamic load rating.
Shielded Construction: Double steel shields (zz designation) provide effective protection against contaminants while minimizing friction compared to contact seals, supporting the 10,000 rpm limiting speed.
Premium Material Composition: Chrome steel rings and balls combined with stainless steel cage deliver excellent wear resistance and corrosion protection, ensuring dimensional stability across the -30°C to 110°C temperature range.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled C0 radial clearance (0.008mm to 0.028mm), providing consistent performance and reduced vibration in precision applications.
6811zz Bearing Typical Application Areas
- Electric Motors: Small to medium-sized motors requiring reliable radial support
- Office Equipment: Printers, copiers, and scanners where compact design is essential
- Medical Devices: Precision instruments requiring smooth, quiet operation
- Industrial Fans & Blowers: Moderate speed applications with continuous operation
- Textile Machinery: Spindles and guiding systems in compact arrangements
- Automotive Components: Auxiliary systems, pumps, and small gearboxes
