Angular Contact Ball B. FAG 3313 -B-TVH-C3

The FAG 3313 -B-TVH-C3 angular contact ball bearing, with dimensions of 65 × 140 × 58.7 mm and a C3 clearance, provides a double-row rolling bearing for combined loads.

The double-row angular contact ball bearing 3313 -B-TVH-C3 accommodates both radial and axial forces on both sides simultaneously, thanks to its contact angle of 40 degrees. As it does not feature integrated seals, this open design is suitable for oil- or grease-lubricated assemblies with external sealing in the surrounding environment. Manufactured from standard roller bearing steel 100Cr6 to tolerance class P0/PN or ABEC 1, the bearing is designed to ensure dimensionally stable guidance of rotating components. The outer ring is supplied in the standard version without a flange or ring groove.

What are the key features of the 3313 -B-TVH-C3 angular contact ball bearing?

This double-row roller bearing is designed to accommodate combined loads and axial guidance forces in both directions within a confined installation space. Compared to two individual bearings mounted opposite each other, the closed assembly requires a smaller axial installation width on the shaft. Typical applications include industrial drives, gearboxes and shaft mountings where rigid guidance of rotating machine components under combined loads is required.

What do C3 radial clearance and a polyamide cage mean in operation?

The design with a slightly increased radial clearance (C3) provides targeted compensation for operational temperature differences between the inner and outer rings. It counteracts excessive stresses caused by the shaft heating up or tighter fits. The integrated polyamide cage guides the two rows of balls with low friction and is characterised by its low weight. Due to the material used, the permissible temperature range is between -20 and +120 degrees.
