Skf 3205 A-2RS1/C3 Angular Contact Ball Bearing

Product Description

The SKF 3205 A-2RS1/C3 is a double-row angular contact ball bearing designed to handle combined radial and axial loads in demanding rotating equipment applications. It features a 30-degree contact angle, a 25 mm bore diameter, and a 52 mm outside diameter with an overall width of 20.6 mm (0.81 inches). The bearing carries a static load capacity of 14,300 lb and a dynamic load capacity of 20,800 lb, making it well suited for high-load, moderate-speed installations. Two integral rubber seals retain grease and exclude contaminants without requiring external shielding. Licensed millwrights, maintenance mechanics, and equipment technicians are the typical installers for this class of bearing.

This bearing is appropriate for use in industrial machinery, pumps, compressors, fans, and similar rotating equipment where combined axial and radial loading occurs on a single shaft position. The double-row configuration provides greater load distribution compared to a single-row design. The C3 internal clearance designation indicates a larger-than-standard radial clearance, which accommodates applications involving interference fits, elevated operating temperatures, or tight housing tolerances. The round bore and without-flange configuration suit standard housing bores machined to metric dimensions.

Key Features

• Double-row design handles simultaneous radial and axial loads
• 30-degree contact angle optimized for combined-load applications
• Double sealed (2RS) construction retains lubrication and blocks contaminants
• C3 internal clearance suits interference-fit or elevated-temperature installations
• Steel cage construction for durability at speed
• ABEC-3 tolerance class for general industrial precision requirements
• Maximum rated speed of 8,000 RPM

Compatibility

Designed as an OEM-style replacement or service bearing for industrial equipment with a 25 mm shaft diameter and a 52 mm housing bore requiring a double-row angular contact ball bearing.

Installation Notes

Bearing installation should be performed by a qualified mechanic or millwright following the equipment manufacturer's assembly procedures. Always de-energize and lock out the equipment before disassembly. Use a proper bearing press or induction heater to seat the bearing; never strike the outer or inner ring directly with a hammer, as this will damage the raceways and seals. Verify housing bore and shaft tolerances before installation to maintain the intended C3 clearance.
