Self-Aligning Ball B. FAG 1204 -TVH

The 1204-TVH self-aligning ball bearing from FAG Wälzlager, with dimensions of 20 × 47 × 14 mm, provides angularly adjustable support for shafts with misalignment.

The 1204 -TVH is a double-row roller bearing made from standard bearing steel (100Cr6) with a cylindrical bore of 20 mm, an outer diameter of 47 mm and a width of 14 mm. The manufacturer, FAG Wälzlager, produces this version with a common hollow-spherical raceway in the outer ring. This enables the bearing to automatically compensate for misalignment between the shaft and the housing. The component has the standard tolerance class P0/PN or ABEC 1 and operates with standard radial clearance.

What is the 1204-TVH self-aligning ball bearing suitable for in operation?

This double-row self-aligning ball bearing is suitable for designs where shaft deflection or misalignment between the bearing seats cannot be completely avoided. Typical applications are found in general mechanical engineering for bearing arrangements with longer shaft spacings or flexible housing structures. As the inner ring and ball set can pivot within the outer ring, this design helps to prevent edge stresses on the rolling elements. The open bearing allows free circulation of lubricants from the surrounding system and primarily accommodates radial loads.

What are the advantages of the polyamide cage in the 1204-TVH self-aligning ball bearing?

The suffix ‘TVH’ indicates that the rolling elements are guided by a lightweight polyamide cage. This cage material operates quietly and has a low moment of inertia, which facilitates acceleration processes within the bearing assembly. The bearing is designed for a temperature range of -30 to +120 degrees. As this is an open bearing without integrated sealing washers, the installation location requires a housing seal fitted on site to prevent the ingress of dirt, as well as a suitable lubrication system using oil or rolling-element bearing grease.
