R2 2rs Bearing Product Overview & Core Advantages
The R2 2RS is a single row deep groove ball bearing engineered for reliable performance in compact spaces. Designed primarily for radial load applications, this inch-series bearing features integral rubber seals (2RS) on both sides for effective contamination exclusion. Its construction from chrome steel components ensures durability, while the ABEC1 precision class offers consistent operation for general industrial use. This sealed bearing is pre-lubricated, simplifying installation and providing immediate, maintenance-free service in a wide operating temperature range.

R2 2rs Bearing Structural Features & Performance Benefits
Robust Sealing System: The dual Nitrile rubber seals (2RS) create an effective barrier against dust, moisture, and other contaminants, significantly extending bearing service life in challenging environments.
Optimized Load Capacity: With a radial dynamic load rating of 121 lbf and radial static load rating of 39 lbf, this bearing delivers reliable performance in various radial load applications.
Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), ensuring smooth operation and reduced vibration.
High-Speed Capability: The stainless steel cage and optimized design enable operation at limiting speeds up to 56,000 rpm, making it suitable for high-speed applications.
Maintenance-Free Operation: Factory-pre-lubricated and sealed construction eliminates the need for relubrication, reducing maintenance requirements and total cost of ownership.
