SKF 3205 ATN9 Double Row Angular Contact Ball Bearing

Description

The SKF 3205 ATN9 is a high-performance double row angular contact ball bearing designed to accommodate both radial and axial loads in both directions. Its design corresponds to two single row angular contact ball bearings arranged back-to-back but requires less axial space. This bearing is suitable for applications where rigid guidance of a shaft is required.

FAQ

The 'A' indicates a 30-degree contact angle, and 'TN9' signifies a snap-type cage made of glass fibre reinforced polyamide 6,6, which is suitable for high speeds and has good temperature resistance.

As an open bearing (no seals or shields), it is not recommended for environments with high levels of contamination unless it is protected by an external sealing arrangement within the machine housing. For dirty environments, a sealed version would be preferable.

It is crucial to apply mounting pressure only to the ring being fitted (press on the inner ring for shaft mounting, outer ring for housing mounting). Uneven pressure can damage the raceways and compromise the bearing's lifespan and performance.
