Jergens 49811 Modular Fixturing Liner Ball Lock 1.3772in Od

Product Description

The JERGENS 49811 is a secondary ball lock modular fixturing liner designed for use in precision workholding and fixture plate systems. This liner provides a repeatable, secure interface between the fixture plate and the ball lock receiver, supporting fast pallet or fixture changeover without sacrificing positional accuracy. It features a 1.3772-inch outside diameter and a 25mm inside diameter, with a plate thickness tolerance of plus or minus 0.0050 inches. Compatible with 0.75-inch plate thickness, the 49811 is a machined component installed by tooling engineers, machine shop technicians, and fixture builders working in CNC machining environments.

The JERGENS 49811 is suited for secondary ball lock system installations where modular fixturing plates are used in horizontal or vertical machining centers. It is intended for installations into 0.75-inch thick fixture plates and integrates with ball lock receiver shanks to enable tool-free, repeatable fixture location. This liner is a standard component in modular fixturing setups common in production machining, job shops, and precision manufacturing environments requiring consistent fixture repeatability.

Key Features

• Secondary ball lock liner type for use in modular fixturing systems
• 1.3772-inch outside diameter for precise press or slip fit into fixture plate bores
• 25mm inside diameter compatible with standard ball lock receiver shanks
• 0.75-inch plate thickness compatibility with 0.0050-inch plate thickness tolerance
• Lightweight at 0.1437 pounds, minimizing added mass to fixture plates

Compatibility

Designed for use with JERGENS Ball Lock modular fixturing systems requiring a secondary liner in 0.75-inch thick fixture plates with a 1.3772-inch bore OD and 25mm ID.

Installation Notes

Installation is typically performed by tooling engineers or machine shop technicians using standard press or hand-fit methods appropriate for the bore tolerance. Ensure the fixture plate bore is clean and within specified tolerances before installing the liner. Verify plate thickness matches the 0.75-inch specified compatibility before installation. Do not force the liner into an undersized bore, as this may compromise positional accuracy or damage the component.
