Self-Aligning Ball B. FAG 1305 -TVH-C3

The 1305 -TVH-C3 self-aligning ball bearing compensates for misalignment caused by shaft movement; it has a 25 mm bore, an outer diameter of 62 mm and a width of 17 mm.

The 1305 -TVH-C3 self-aligning ball bearing from FAG Rolling Bearings is a double-row rolling bearing made from standard 100Cr6 bearing steel. It absorbs radial forces and accommodates misalignment between the shaft and housing. Thanks to the hollow-spherical design of the outer ring, the ball set moves within the bearing with adjustable angular misalignment. This design features a standard inner ring and complies with tolerance class P0/PN or ABEC 1.

What is the 1305 -TVH-C3 self-aligning ball bearing suitable for in operation?

The 1305 -TVH-C3 self-aligning ball bearing is designed for bearing arrangements where shaft deflection or misalignment between the bearing positions may occur. Typical applications include shaft mountings with longer support spans or flexible substructures. As this is an open bearing without integrated seals, lubrication is provided by grease or oil from the housing environment. The permissible temperature range is from –30 to +120 degrees Celsius.

What do the polyamide cage and the C3 clearance mean?

The material of the cage and the bearing clearance determine the running characteristics. The designation TVH indicates a polyamide cage, which guides the rolling elements and keeps the moment of inertia of the rotating mass low. The suffix ‘C3’ indicates a slightly increased radial bearing clearance compared with the standard clearance. This increased operating clearance helps to prevent the rolling elements from seizing up when operational temperature differences occur between the inner and outer rings, or when tight fits cause the inner ring to expand.
