Self-Aligning Ball B. FAG 1307 -TVH

The FAG 1307-TVH self-aligning ball bearing (35x80x21 mm) compensates for misalignment with its double-row design and operates particularly quietly thanks to its polyamide cage.

The 1307-TVH self-aligning ball bearing is a double-row rolling bearing with a common hollow-spherical outer ring raceway. With key dimensions of a 35 mm bore, 80 mm outer diameter and 21 mm width, this bearing is used where shafts deflect or misalignment occurs between housing bores. The manufacturer, FAG, produces this bearing from standard roller bearing steel (100Cr6) with standard radial clearance and tolerance class P0/PN or ABEC 1. Design engineers and maintenance personnel are provided with a versatile component for demanding mechanical environments.

In which installation scenarios does the 1307-TVH self-aligning ball bearing compensate for misalignment?

This double-row bearing is designed for applications where operational misalignments or shaft deflection between the inner and outer rings need to be compensated for. Typical applications include designs with longer shafts or multi-part housings, where misalignments may occur. Thanks to the spherical outer ring raceway, the ball set automatically adjusts to angular misalignment, thereby helping to prevent edge loading. The component is used in applications where rigid deep-groove ball bearings would be overloaded due to misalignment.

What is the function of the polyamide cage in the 1307-TVH self-aligning ball bearing?

The suffix -TVH denotes the version with a polyamide cage. This material reduces the weight of the rotating assembly, ensures quiet operation and minimises friction during ball rotation. As this is an open bearing without an integrated seal, the lubricant must be selected to suit the operating environment. The permissible temperature range is from –30 to +120 degrees Celsius. The bearing housing requires an external housing seal to protect the bearing from ingress of dirt and moisture.
