Browning 1297225 Chain Idler Sprocket Steel Chain Size 25

Product Description

The BROWNING 1297225 is a steel chain idler sprocket designed to maintain tension and guide alignment in roller chain drive systems. With an outside diameter of 1.65 inches and compatibility with No. 25 chain, this sprocket serves as a passive tensioning component in light-duty chain drive assemblies. It is commonly installed by mechanical technicians and maintenance professionals working on conveyor systems, packaging equipment, and small machinery where chain slack must be controlled. The steel construction provides durability under repetitive contact with the chain strand.

This idler sprocket is suited for light industrial and commercial applications where No. 25 roller chain is the specified drive chain. Typical install scenarios include compact conveyor lines, agricultural equipment, and small power transmission assemblies requiring a fixed or adjustable idler position to reduce chain vibration and prevent derailment. At 0.1 pounds, the low mass makes it practical for applications where added rotating weight is a concern.

Key Features

• Outside diameter of 1.65 inches fits compact sprocket bay layouts
• Designed for No. 25 roller chain drive systems
• Steel construction resists wear under continuous chain contact
• Lightweight at 0.1 pounds, minimizing added rotational inertia
• Single-unit packaging allows for individual replacement without bulk purchase requirements

Compatibility

Designed as an OEM-style replacement or upgrade idler for light-duty No. 25 roller chain drive assemblies in industrial and commercial power transmission applications.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with chain drive systems. Disengage and lock out all power to the drive system before removing or installing any sprocket or idler component. Verify proper chain alignment and tension after installation to prevent premature wear on the idler and chain. Consult the equipment manufacturer's service documentation for mounting hardware specifications and idler positioning requirements.
