Browning 1297266 Chain Idler Sprocket Ansi 40 19 Tooth Steel

Product Description

The BROWNING 1297266 is a single-strand chain idler sprocket designed to maintain tension and guide alignment in ANSI No. 40 roller chain drive systems. Manufactured from steel, it features a 19-tooth count and a 3.28-inch outside diameter, making it a direct-fit option for light-to-medium-duty power transmission applications. With a 0.5-inch chain pitch conforming to ANSI standards, this sprocket provides consistent chain engagement and helps reduce wear across the entire drive assembly. Licensed mechanics and industrial maintenance technicians commonly specify this part for conveyor systems, agricultural equipment, and general machinery where reliable chain drive performance is required.

This idler sprocket is suited for use in single-strand No. 40 roller chain applications across a range of industrial and commercial machinery setups. Typical installations include conveyor lines, packaging equipment, light industrial drive assemblies, and agricultural machinery drives where an idler is needed to control chain slack, redirect chain path, or maintain proper tension without transmitting torque. The steel construction provides durability in moderate-load environments.

Key Features

• ANSI No. 40 chain compatibility with 0.5-inch pitch for standardized fitment
• 19-tooth configuration delivers smooth chain engagement and consistent drive performance
• 3.28-inch outside diameter suitable for space-constrained drive layouts
• Single-strand design for use with standard No. 40 roller chain
• Steel construction for durability in moderate-duty power transmission applications
• Conforms to ANSI standards for interchangeability with compatible sprocket components

Compatibility

Designed as an OEM-style replacement idler sprocket for single-strand ANSI No. 40 roller chain drive systems requiring a 19-tooth, 0.5-inch pitch sprocket.

Installation Notes

Installation should be performed by a qualified industrial mechanic or maintenance technician. Disengage and lock out all power to the drive system before removing or installing any sprocket or chain component, following OSHA lockout/tagout procedures. Verify proper chain alignment and tension after installation to prevent premature wear. Inspect the mating roller chain and all adjacent drive components for wear before placing the system back in service.
