Browning 1297274 Chain Idler Sprocket Size 50 17T Steel

Product Description

The BROWNING 1297274 is a single-strand chain idler sprocket designed to maintain tension and guide chain in power transmission drive systems. Built to ANSI standards, this sprocket features a 3.72-inch outside diameter, 17 teeth, and a 0.625-inch pitch compatible with Size 50 roller chain. Constructed from steel, it delivers reliable durability in industrial and mechanical drive applications. This is a passive idler component, meaning it does not transmit torque but instead controls chain path and slack. Technicians and maintenance professionals working on conveyor systems, mechanical drives, and automated equipment will find this a direct-spec replacement.

This sprocket is suited for single-strand Size 50 roller chain applications in light to medium industrial drive systems. Typical install scenarios include conveyor lines, packaging equipment, agricultural machinery, and general mechanical power transmission assemblies where a tensioning or guiding sprocket is required. The ANSI-standard design ensures dimensional conformance across compatible chain and sprocket assemblies.

Key Features

• Size 50 single-strand roller chain compatibility per ANSI standards
• 17-tooth count with 0.625-inch pitch for precise chain engagement
• 3.72-inch outside diameter for defined chain path geometry
• Steel construction for durability in industrial environments
• Idler configuration maintains chain tension without transmitting drive torque

Compatibility

Designed for use with ANSI Size 50 single-strand roller chain in standard power transmission drive assemblies.

Installation Notes

Installation should be performed by a qualified maintenance technician or millwright. De-energize and lock out the drive system before beginning any sprocket service or chain work, following applicable LOTO procedures. Ensure the idler is properly aligned with the drive and driven sprockets to prevent premature chain wear. Do not overtighten the chain when setting idler position, as proper slack allowance is required per the drive manufacturer guidelines.
