6811 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling significant radial loads while accommodating moderate axial loads in both directions
- Sealed Construction: The double rubber seals (2RS) provide excellent defense against dust, moisture, and other contaminants, significantly extending bearing service life and reducing maintenance needs
- High-Quality Materials: Chrome steel rings and balls combined with a stainless steel cage ensure high durability, corrosion resistance, and stable operation under dynamic loads
- Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0) for consistent, low-vibration performance
- Compact & Lightweight: With a 9mm width and weight of only 83 grams, it is an ideal solution for space-constrained and weight-sensitive applications
6811 2rs Bearing Typical Application Areas
- Electric Motors and Small AC/DC Motors
- Power Tools and Handheld Electric Appliances
- Office Automation Equipment (Printers, Scanners, Copiers)
- Medical Devices and Low-Noise Instrumentation
- Automotive Auxiliary Systems (Fans, Pumps, Blowers)
- Food Processing Machinery (with appropriate lubrication)
