61810-2RS1 Bearing Structural Features & Performance Benefits
Optimized for Compact Design: The single row, deep groove raceway and minimal 7mm width make this bearing a premier solution for applications with severe space constraints, offering a high load capacity relative to its size.
Robust Load Capacity: Manufactured from chrome steel rings and balls, this bearing provides a radial dynamic load rating of 1520 lbf and a radial static load rating of 1529 lbf, ensuring reliable performance under significant radial stresses.
Enhanced Service Life & Reliability: The stainless steel cage ensures stability at high speeds, while the 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants. Pre-lubricated with grease, it offers a ready-to-install, low-maintenance solution.
Precision Performance: Manufactured to P6 tolerance class with a CN radial internal clearance, this bearing guarantees running accuracy and consistent operation, which is critical for precision mechanisms.
