Jergens 49701 Modular Fixturing Liner Primary Ball Lock

Product Description

The JERGENS 49701 is a primary ball lock modular fixturing liner designed for use in precision workholding and modular fixturing systems. This liner press-fits into a receiver plate to establish a repeatable, zero-point location point for pallets and fixtures on machining centers and fixture plates. With an outside diameter of 1.3772 inches, an inside diameter of 20mm, and compatibility with 3/4-inch plate thickness, it provides a rigid, accurate seating surface for ball lock shanks. Installation is typically performed by toolroom machinists or fixturing technicians working on CNC workholding setups.

The 49701 is suited for modular fixturing applications in manufacturing environments where rapid changeover and repeatable part location are required. It is intended for use in fixture plates or tombstones machined to accept ball lock components at the specified plate thickness of 0.75 inches. The primary liner designation indicates it serves as the main locating element within the ball lock system.

Key Features

• Outside diameter of 1.3772 inches for precise press-fit installation into receiver plates
• Inside diameter of 20mm to accept standard ball lock shank components
• Compatible with 0.75-inch plate thickness
• Plate thickness tolerance of 0.0050 inches for controlled seating depth
• Primary liner type for use as the main locating element in ball lock fixturing systems

Compatibility

Designed for use with ball lock modular fixturing systems in plates with 0.75-inch thickness. Consult the JERGENS ball lock system documentation to confirm shank and receiver plate compatibility before installation.

Installation Notes

Installation is typically performed by a toolroom machinist or fixturing technician. The liner is press-fit into a precision-bored hole in the fixture plate; ensure the bore diameter and surface finish meet the manufacturer's specifications before installation. Power down and lock out any connected machine before servicing or replacing fixturing components. Verify plate thickness and bore depth against liner specifications prior to pressing the liner into the plate.
