Skf 3207 A-2RS1/C3 Angular Contact Ball Bearing

Product Description

The SKF 3207 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, which allows it to carry significant thrust loads in addition to radial forces. The bearing carries a dynamic load capacity of 37,700 pounds and a static load capacity of 27,500 pounds, making it well suited for high-load industrial drive and support applications. Two integral rubber seals retain lubrication and exclude contaminants without requiring external sealing hardware. Licensed technicians and mechanical maintenance professionals typically install this bearing in machinery where both speed and load reliability are critical.

This bearing fits rotating equipment in industrial, HVAC, and mechanical drive applications where double-row support is required to resist combined loading. Typical installation scenarios include electric motor shafts, pump housings, gearbox input shafts, and fan drive assemblies operating at speeds up to 6,000 RPM. The C3 internal clearance designation indicates a looser-than-standard fit, appropriate for applications where thermal expansion during operation is expected. The double-seal configuration makes this bearing a maintenance-friendly option in environments where relubrication access is limited.

Key Features

• 30-degree contact angle supports combined radial and axial loading
• Double-row design provides increased load capacity and shaft support stiffness
• Two integral seals enclose factory lubrication and block contamination ingress
• C3 internal clearance accommodates thermal expansion in high-temperature or interference-fit installations
• Steel cage construction for durability under continuous high-cycle operation
• ABEC-3 precision rating suitable for industrial machinery tolerances

Compatibility

Designed as an OEM-style replacement double-row angular contact ball bearing for industrial rotating equipment requiring a 35 mm bore, 72 mm outside diameter, and 27 mm width with C3 clearance and double-seal configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize and lock out all power to the equipment before removing the existing bearing. Use a bearing press or induction heater to seat the bearing properly - never strike the outer or inner race directly with impact tools, as this will damage the raceways. Verify that housing bore and shaft diameter tolerances are within specification before installation to preserve the C3 clearance designation.
