Double row angular contact bearings 3303-2RS/P5

3303-2RS/P5 angular bearings are double row sealed angular bearings designed for high precision P5 performance in demanding applications with radial and axial load capacity.

Specification

SEODescription

The 3303-2RS/P5 angular bearings are double row sealed angular contact bearings designed for high-precision applications requiring combined axial and radial load capacity. These High precision P5 bearings feature a robust double-row configuration with 30° contact angles, enabling superior rigidity and reduced deflection under multi-directional forces. The 3303-2RS/P5 model incorporates integrated rubber seals (2RS) to retain lubrication and exclude contaminants, ensuring durability in harsh environments. With a P5-grade tolerance, they deliver exceptional rotational accuracy (±0.0025 mm) and low noise operation, suitable for CNC spindles, robotics, and precision gearboxes. Operating temperature ranges from -30°C to +120°C with grease lubrication. Advantages include extended service life and reduced maintenance, though their double-row design requires precise alignment during installation. Widely used in machine tools, automation systems, and high-speed industrial drives.
