Double row angular contact bearings model 3807A-2RS/P5 feature high precision sealed construction for durable radial-axial load capacity in industrial machinery applications.

Specification

SEODescription

The Double row angular contact bearings model 3807A-2RS/P5 are high precision sealed bearings engineered for dual-direction axial-radial load support in compact spaces. Featuring dual rubber seals (2RS) for dust/moisture resistance and P5-grade tolerance (±0.0025mm runout), they deliver exceptional rotational accuracy at speeds up to 8,000 rpm. Optimized for -40°C to +150°C operation, these bearings integrate two angular contact raceways to handle combined loads up to 35kN dynamic/22kN static. Widely used in CNC spindles, robotics joints, and medical equipment, their double-row design enhances stiffness while reducing axial space by 30% versus single-row alternatives. Key advantages include reduced vibration, extended lubricant retention, and simplified maintenance due to pre-lubricated sealed construction. Limitations include higher initial cost compared to open-type bearings and sensitivity to improper preload adjustment during installation, requiring skilled mounting in precision alignment systems.
