Skf 3204 A-2RS1 Angular Contact Ball Bearing 20mm Bore

Product Description

The SKF 3204 A-2RS1 is a double-row angular contact ball bearing designed to handle combined radial and axial loads in demanding industrial and mechanical applications. It features a 30-degree contact angle, which allows it to manage significant thrust loads in both directions simultaneously. With a dynamic load capacity of 19,000 pounds and a static load capacity of 12,000 pounds, this bearing is built for high-load environments. The double-seal (2RS1) configuration and steel cage provide contamination resistance and structural integrity across a wide range of operating speeds up to 9,000 RPM. Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals are the typical installers.

This bearing is suited for residential and light commercial mechanical systems, pump assemblies, fan shaft applications, compressor drives, and general industrial machinery where combined load capacity and contamination resistance are required. The double-row design makes it a practical choice for applications where a single-row bearing would be insufficient for the axial load demands. Its round bore and standard metric dimensions allow straightforward fitment in new builds and replacement scenarios alike.

Key Features

• 30-degree contact angle supports simultaneous radial and axial loading
• Double-row configuration delivers higher load capacity than single-row equivalents
• Double-sealed (2RS1) design resists contamination without requiring external shielding
• Steel cage provides durability at speeds up to 9,000 RPM
• ABEC-3 precision rating ensures consistent dimensional tolerances
• No snap ring or flange - clean installation into standard bearing housings

Compatibility

Designed as an OEM-style replacement double-row angular contact ball bearing for equipment with a 20 mm round bore shaft and a 47 mm bore housing requiring a 30-degree contact angle bearing.

Installation Notes

Installation should be performed by a qualified mechanical technician or maintenance professional. Always de-energize and lock out the equipment before removing or installing bearings. Use a proper bearing press or induction heater to seat the bearing - never strike the bearing directly with a hammer, as this can damage the races and seals. Verify shaft and housing tolerances against the bearing specifications before pressing to avoid preload issues.
