Browning 1296938 Tightener Shaft 2-5/16 in Drive Idler

Product Description

The BROWNING 1296938 is a tightener shaft designed for use in drive tightener and idler assemblies. Machined from 52100-grade steel, this shaft measures 2-5/16 inches in overall length with a shaft diameter of 1/2 inch and a shaft length of 1-1/2 inches. It is a direct-replacement component used to restore proper belt tension in mechanical drive systems. Maintenance mechanics and industrial technicians working on conveyor, HVAC blower, or other belt-driven equipment install this shaft when replacing worn or damaged tightener hardware.

This tightener shaft fits drive tightener and idler applications across a range of belt-drive assemblies found in light industrial and commercial mechanical systems. Its compact dimensions make it suited for confined drive housings where space is limited. The 52100 steel material grade provides good wear resistance for rotating contact applications typical in belt tensioning service.

Key Features

• 52100 steel material grade for wear resistance in rotating drive applications
• Overall length of 2-5/16 inches fits compact tightener assemblies
• 1/2-inch shaft diameter compatible with standard drive tightener bores
• Shaft length of 1-1/2 inches provides adequate engagement depth in tightener hardware
• Width of 1/2 inch matches standard idler and tightener shaft profiles

Compatibility

Designed as a direct-replacement tightener shaft for drive tightener and idler assemblies requiring a 1/2-inch diameter shaft with a 2-5/16-inch overall length.

Installation Notes

Installation is typically performed by a maintenance mechanic or millwright. De-energize and lock out the drive system before removing the existing shaft or disturbing any belt tension components. Verify shaft diameter and overall length against the tightener assembly specifications before installation. Follow applicable machinery safety standards and site lockout/tagout procedures throughout the service process.
