Browning 1297993 Offset Link 50 Chain 5/8 Inch Pitch

Product Description

The BROWNING 1297993 is a steel offset link designed for use with single-strand roller chain in ANSI 50 chain drives. An offset link — also called a half link — allows technicians to adjust chain length by an odd number of pitches, making it a critical spare for drive maintenance and repair. This link features a 5/8-inch pitch, a 0.400-inch roller diameter, and a 0.375-inch roller width, keeping it fully compliant with ANSI standards for No. 50 chain. Installation is handled by licensed mechanics and industrial service technicians working on conveyor, drive, and power transmission systems.

This offset link is suited for light-to-medium duty single-strand roller chain applications found in industrial machinery, conveyor systems, and mechanical power transmission drives. It is used wherever a standard even-link connection cannot be made and a half-pitch adjustment is required. The pin-style attachment type allows straightforward assembly with standard chain tools. Typical environments include manufacturing facilities, agricultural equipment, and HVAC or mechanical equipment rooms using chain-driven components.

Key Features

• Designed for ANSI No. 50 single-strand roller chain with 5/8-inch pitch
• Steel construction for durability in mechanical drive applications
• Pin attachment type for assembly with standard chain break and press tools
• 0.400-inch roller diameter and 0.375-inch roller width match No. 50 chain geometry
• Meets ANSI standards for dimensional and load compatibility
• Compact and lightweight at 0.05 pounds for easy on-site stocking

Compatibility

Designed as an OEM-style replacement offset link for ANSI No. 50 single-strand roller chain applications. Verify chain pitch, roller diameter, and roller width match the existing drive chain before installation.

Installation Notes

Installation should be performed by a qualified mechanic or power transmission technician. De-energize and lock out the drive system completely before removing or installing any chain link. Use a proper chain break tool and connecting-link press to seat the clip or pin retainer — do not hammer components into place, as this can damage the link plate or distort the pin. Inspect adjoining chain links and sprocket teeth for wear before returning the drive to service.
