Jergens 49706 Primary Ball Lock Modular Fixturing Liner

Product Description

The JERGENS 49706 is a primary-type ball lock modular fixturing liner designed for use in precision workholding and modular fixturing systems. It accepts a 13mm inside diameter and features an outside diameter of 0.7518 inches, allowing it to press or seat into fixturing plates up to 0.75 inches thick. The liner serves as the receiver component in a ball lock system, enabling repeatable, tool-free pallet and fixture changes on machine tool tables. Installation is typically performed by toolmakers and fixture builders working in machining environments where positional repeatability is critical.

This liner is suited for shop-floor fixturing applications in CNC machining centers, milling cells, and modular tombstone setups. The primary designation indicates it functions as the base-plate receiver rather than a subplate or secondary component. With a plate thickness tolerance of plus or minus 0.0050 inches, it accommodates standard fixture plate stock. At 0.05 pounds, it is a lightweight component well suited to dense multi-fixture layouts where weight and space savings matter.

Key Features

• Primary liner type for ball lock modular fixturing systems
• Outside diameter of 0.7518 inches for close-tolerance plate installation
• 13mm inside diameter to accept standard ball lock shanks
• Compatible with 0.75-inch plate thickness within a 0.0050-inch tolerance
• Lightweight at 0.05 pounds for use in multi-component fixture builds

Compatibility

Designed as an OEM-style replacement or build component for ball lock modular fixturing systems requiring a primary liner in 0.75-inch plate stock with a 13mm ID.

Installation Notes

Installation is typically performed by a toolmaker or fixture technician. The liner should be pressed or installed into the fixturing plate using appropriate tooling to avoid damage to the bore or plate surface. Ensure the machine tool is fully powered down and the fixture plate is clean and deburred before installation. Verify plate thickness falls within the stated tolerance range before seating the liner.
