Self-Aligning Ball B. FAG 2207 -TVH

The FAG 2207-TVH self-aligning ball bearing automatically compensates for misalignment and, with dimensions of 35 × 72 × 23 mm, offers a proven load-carrying capacity for angularly movable shaft mountings.

The double-row self-aligning ball bearing 2207 -TVH from FAG Rolling Bearings is characterised by its hollow-spherical outer ring raceway. This design enables the two rows of balls to compensate for angular misalignment between the shaft and housing. Manufactured from 100Cr6 rolling-bearing steel, the bearing complies with the standard tolerance class P0/PN (ABEC 1). With a bore of 35 mm, an outer diameter of 72 mm and a width of 23 mm, this roller bearing is suitable for industrial applications where elastic shaft deflection may occur.

In which operating conditions does the 2207-TVH self-aligning ball bearing compensate for misalignment?

The spherical raceway in the outer ring allows the balls to adjust freely when the shaft is misaligned relative to the bearing housing. This prevents unacceptable edge pressures when shafts deflect elastically or when misalignment errors arising from the manufacturing process occur. Designs with longer support spans or dynamic deflection make use of this angularly adjustable design. The open design facilitates lubricant access via the surrounding machine housing and keeps friction losses to a minimum during operation.

What is the function of the TVH polyamide cage?

The suffix TVH denotes a moulded, solid polyamide cage that guides the rolling elements precisely. The material provides an elastic ball bearing surface, dampens running noise and reduces the weight of the rolling element set. In conjunction with the standard radial bearing clearance, this design covers an operating temperature range from –30 to +120 degrees Celsius. As the bearing is supplied unsealed, lubrication and protection against contamination are provided on site via the housing.
