Self-Aligning Ball B. FAG 2205 -TVH

The FAG 2205-TVH double-row self-aligning ball bearing, measuring 25 × 52 × 18 mm, compensates for misalignment and supports shafts prone to deflection.

The 2205-TVH self-aligning ball bearing is a double-row rolling bearing with a hollow-spherical outer ring raceway for shafts with a diameter of 25 mm. Thanks to this spherical geometry, the bearing automatically compensates for misalignment and shaft deflection during operation. FAG manufactures this type from standard bearing steel 100Cr6 with standard radial clearance and tolerance class P0/PN or ABEC 1. The open design allows for direct lubricant supply via the surrounding structure.

What is the 2205-TVH self-aligning ball bearing suitable for in operation?

Its use is particularly recommended where misalignment occurs between bearing seats or where shafts deflect elastically under load. The two rows of balls distribute radial forces evenly across the common spherical raceway of the outer ring. Typical areas of application are found in general mechanical engineering, particularly in long shaft runs prone to angular misalignment. As this is an open bearing, it can be flexibly integrated into oil- or grease-lubricated assemblies.

What advantages does the TVH polyamide cage offer for the design?

The polyamide material gives the cage high elasticity and reduces the overall weight of the component. The TVH design is characterised by low-vibration operation and low friction. The bearing operates within a temperature range of -30 to +120 degrees Celsius. When designing the application, it must be borne in mind that the 25x52x18 mm open self-aligning ball bearing requires a clean installation environment to prevent dirt particles from entering the unprotected raceways.
