Self-Aligning Ball B. FAG 2205 -2RS-TVH

The FAG 2205 -2RS-TVH self-aligning ball bearing (25x52x18 mm) compensates for misalignment and, thanks to its 2RS seal, provides effective protection against contamination.

The FAG 2205 -2RS-TVH double-row self-aligning ball bearing is a rolling bearing made from standard bearing steel (100Cr6) with a cylindrical bore of 25 mm, an outer diameter of 52 mm and a width of 18 mm. The design, featuring a common hollow spherical raceway in the outer ring, serves to compensate for static and dynamic angular misalignments between the shaft and housing. Design engineers and maintenance personnel use this design primarily where misalignment or deflection occurs and protection against the ingress of foreign particles is required at the same time.

Under what operating conditions does the 2205-2RS-TVH self-aligning ball bearing prove its worth?

This double-row rolling bearing is used wherever misalignments in housing bores or elastic deflections of rotating shafts need to be reliably compensated for. Typical operating conditions include bearing locations with high levels of dust and dirt, where open designs would wear out quickly. Thanks to the double-sided sliding seal, the lubricant remains protected within the bearing chamber, meaning that no external housing seal is required against moderate contamination.

What are the functions of the 2RS seal and the TVH polyamide cage?

The 2RS seal, which abuts on both sides, protects against the ingress of dirt and moisture and reliably retains the lubricant inside the bearing. The TVH polyamide cage is characterised by its elastic guidance of the rolling elements, low weight and smooth running. The bearing is designed for temperatures ranging from -30 to +100 degrees. It is manufactured with standard radial bearing clearance and the standard tolerance class P0/PN (ABEC 1), suitable for common bearing seats in mechanical engineering.
