6805 2rs Bearing Product Overview & Core Advantages
The 6805 2RS is a metric single row deep groove ball bearing featuring integral contact seals (2RS) on both sides. Engineered for radial load applications, this compact bearing delivers reliable performance in space-constrained environments. Manufactured to ABEC-1 precision tolerances with optimized radial internal clearance (C0), it ensures smooth operation and extended service life. The combination of chrome steel rings, chrome steel balls, and stainless steel cage provides excellent durability and corrosion resistance.

6805 2rs Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables efficient radial load distribution while accommodating moderate axial loads in both directions.
Integrated Sealing System: The 2RS rubber contact seals provide excellent protection against contaminants while maintaining low friction characteristics, contributing to the 21,000 rpm limiting speed.
Precision Construction: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.006-0.020mm) ensures consistent performance and reduced vibration.
Material Excellence: The combination of chrome steel rings and balls with stainless steel cage provides optimal strength, wear resistance, and corrosion protection for demanding applications.
6805 2rs Bearing Typical Application Areas
- Electric Motors: Small to medium-sized motors requiring reliable radial bearing support with contamination protection
- Power Tools: Compact drills, grinders, and saws where space constraints and sealed bearing performance are critical
- Industrial Gearboxes: Light to medium-duty gear reduction units requiring precision ball bearings
- Pumps and Compressors: Small fluid handling equipment where sealed construction prevents lubricant washout
- Medical Equipment: Diagnostic devices and laboratory instruments requiring quiet operation and reliability
- Office Automation: Printers, scanners, and copiers utilizing compact precision bearings
