Browning 1296979 Tightener Shaft 5-11/16 in Oal

Product Description

The BROWNING 1296979 is a tightener shaft designed for use in drive tightener and idler assemblies. Machined from 52100-grade steel, it provides the rigidity and wear resistance required in belt drive systems subject to continuous load and tension cycling. The shaft measures 5-11/16 inches overall length with a 1-1/2 inch shaft diameter and a 4 inch shaft length. At 2.8 pounds, it is sized for industrial and commercial drive applications where a robust, dimensionally precise shaft is needed to maintain proper belt tension and alignment. Licensed mechanics and drive system technicians are the typical installers.

This tightener shaft is suited for belt drive systems requiring a replacement or new-installation shaft in drive tightener and idler configurations. It is appropriate for industrial conveyor, HVAC blower, and mechanical power transmission setups where 52100 steel construction and precise shaft dimensions are specified. The 1-1/2 inch diameter and 4 inch shaft length make it compatible with tightener assemblies that call for those exact dimensions.

Key Features

• 52100-grade steel construction for high hardness and fatigue resistance under cyclic belt loading
• 5-11/16 inch overall length with 1-1/2 inch shaft diameter and 4 inch shaft length
• Designed for drive tightener and idler applications requiring precise shaft fitment
• Weighs 2.8 pounds — substantial construction suitable for continuous-duty drive systems
• Sold individually — one shaft per package

Compatibility

Designed as an OEM-style replacement or direct-fit shaft for drive tightener and idler assemblies requiring a 1-1/2 inch diameter, 4 inch shaft length, and 5-11/16 inch overall length configuration.

Installation Notes

Installation of tightener shafts is typically performed by qualified mechanical or drive system technicians. De-energize and lock out the drive system fully before removing any belt tension components. Verify shaft diameter, length, and material grade match the tightener assembly specifications before installation. Refer to the drive system manufacturer documentation for proper torque and belt tension procedures.
