Self-Aligning Ball B. FAG 2218 -TVH

The FAG 2218-TVH self-aligning ball bearing (90x160x40 mm) compensates for misalignment and guides shafts using a flexible polyamide cage.

The 2218-TVH self-aligning ball bearing provides designers with a double-row rolling bearing for demanding shaft support applications. The shared hollow-spherical raceway in the outer ring allows the inner ring to angle outwards, enabling the design to reliably accommodate misalignment and shaft deflection during operation. FAG manufactures this bearing from standard rolling-element bearing steel 100Cr6 with standard radial clearance and a cylindrical bore. This design is suitable for applications where housing misalignment occurs due to manufacturing tolerances or where misalignment arises during operation.

What is the 2218-TVH double-row self-aligning ball bearing suitable for?

The use of this self-aligning bearing is particularly recommended where elastic deformations of the shaft or misalignments between the bearing seats occur. Typical applications include long shafts and elastic support structures. As the bearing distributes radial loads across two rows of balls, the design absorbs continuous transverse forces. The angular-contact design protects the raceways from sharp load peaks and ensures smooth shaft rotation even in the event of misalignment.

What advantages does the TVH polyamide cage offer in practice?

The TVH suffix denotes a solid polyamide cage which guides the balls precisely and contributes to smooth running. The material dampens sudden accelerations, reduces operating noise and keeps frictional resistance low. The bearing is designed for a temperature range of -30 to +120 degrees. As it features an open design without an integrated seal, the lubricant can be flexibly adapted to the operating conditions and integrated into an existing lubrication system.
