Self-Aligning Ball B. FAG 1202 -TVH-C3

The FAG 1202-tvh-c3 double-row self-aligning ball bearing automatically compensates for misalignment and, with its polyamide cage and C3 clearance, offers smooth running with an outer diameter of 35 mm.

The 1202-tvh-c3 self-aligning ball bearing from FAG Rolling Bearings is a double-row rolling bearing made from standard bearing steel for industrial shaft mountings. Thanks to the shared hollow-spherical raceway in the outer ring, the bearing automatically adjusts to shaft deflection. This open design, with a cylindrical bore and a width of 11 mm, is suitable for applications where the lubricant is supplied directly via the surrounding housing. The component meets the requirements for angular contact bearings in general mechanical engineering.

Under what operating conditions does the 1202-tvh-c3 self-aligning ball bearing compensate for misalignment?

The double-row design is primarily used to accommodate shaft deflection or misalignment between bearing positions. As the balls can tilt on the spherical outer ring raceway, the component counteracts edge pressures on the raceways. This reduces internal friction and protects the bearing seats during dynamic angular deviations in operation. Designs featuring elastically yielding shafts or manufacturing-related axial misalignments benefit from this design-related angular compensation.

What do C3 bearing clearance and a polyamide cage mean for operation?

The suffix C3 indicates a slightly increased radial clearance. This internal clearance between the rolling elements and raceways prevents seizing when temperature differences occur between the shaft and housing, or when tight fits cause the inner ring to expand. The polyamide cage guides the rolling elements quietly and with low vibration. It withstands thermal loads from -30 to +120 °C and, due to its open design, requires an external lubrication supply with suitable grease or bearing oil.
