Self-Aligning Ball B. FAG 1203 -TVH-C3

FAG 1203 -TVH-C3 self-aligning ball bearing with a 17 mm bore, a hollow-spherical outer ring raceway and increased C3 clearance for angular misalignment compensation.

The 1203 -TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 17x40x12 mm. Thanks to the common hollow-spherical raceway in the outer ring, the bearing automatically compensates for shaft deflection or misalignment. This FAG product is supplied as an open bearing without integrated sealing washers and is suitable for operating temperatures ranging from -30 to +120 degrees Celsius.

In which installation scenarios does the 1203 -TVH-C3 self-aligning ball bearing compensate for misalignment?

This bearing is used when operational shaft deflection or misalignment between the housing and the shaft needs to be compensated for. Typical applications include bearing arrangements with long shafts or elastic deformations under radial loads. As this is an open design without integrated sealing elements, the component is designed for oil- or grease-lubricated bearing arrangements where sealing is provided externally via the housing design.

What do the TVH polyamide cage and the C3 clearance mean?

The suffix TVH denotes a polyamide cage, which guides the rolling elements with low vibration and reduces the moment of inertia compared to metal cages. The designation C3 indicates a slightly increased radial bearing clearance compared with the standard CN version. This additional bearing clearance helps to prevent stress build-up during operation when temperature differences occur between the inner and outer rings, or when a tight fit causes the inner ring to expand.
