Self-Aligning Ball B. FAG 2308 -TVH

The FAG 2308-TVH double-row self-aligning ball bearing, measuring 40 × 90 × 33 mm, compensates for misalignment and supports shafts under radial loads.

The FAG 2308-TVH self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a cylindrical bore. The common hollow-spherical raceway in the outer ring allows the rows of balls to deflect, thereby compensating for misalignment between the shaft and the housing. With an inside diameter of 40 mm, an outside diameter of 90 mm and a width of 33 mm, this open bearing complies with tolerance class P0/PN (ABEC 1).

What is the 2308-TVH self-aligning ball bearing suitable for?

Design engineers and maintenance technicians primarily use this design where shafts deflect under radial loads or where manufacturing-related misalignments occur between the bearing positions. As this is an open bearing, lubricant can reach the raceways unhindered, allowing the lubricant to be adapted to the specific operating conditions. The component is primarily used in bearing applications where it is structurally difficult to maintain precise housing alignment.

What function does the TVH polyamide cage fulfil during operation?

The suffix ‘TVH’ denotes a polyamide cage that maintains an even spacing between the two rows of balls. Compared to heavier metal cages, the lightweight material reduces the moving mass and promotes low-vibration operation. The version with standard radial clearance is suitable for operating temperatures ranging from -30 to +120 degrees. As the bearing is of open design, a housing seal fitted on site protects the interior from dirt and prevents lubricant loss.
