Jergens 49707 Ball Lock Modular Fixturing Liner

Product Description

The JERGENS 49707 is a primary-type modular fixturing liner designed for ball lock workholding systems used in precision machining and fixturing applications. With an outside diameter of 1.0018 inches and a 16mm inside diameter, this liner installs into fixture plates to provide a repeatable, accurate receiver for ball lock shanks. It is compatible with 0.5-inch plate thickness and carries a plate thickness tolerance of plus or minus 0.0050 inches. Licensed machinists, toolroom technicians, and fixturing specialists install this component as part of a quick-change pallet or modular fixturing setup on CNC mills, machining centers, and tombstone fixtures.

This liner suits primary positioning duties in modular fixturing systems that rely on ball lock technology for rapid, repeatable workholding changeovers. It is sized for installation in fixture plates with a nominal 0.5-inch thickness, making it well suited for standard subplate and tombstone configurations common in production and job-shop machining environments. The 16mm ID accommodates standard ball lock shank sizes used across modular fixturing platforms.

Key Features

• Primary liner type for ball lock modular fixturing systems
• Outside diameter of 1.0018 inches for precise press or slip fit into receiver bores
• 16mm inside diameter sized to accept standard ball lock shanks
• Designed for 0.5-inch plate thickness with a 0.0050-inch plate thickness tolerance
• Lightweight at 0.0625 pounds for minimal fixture weight addition

Compatibility

Designed as an OEM-style component for ball lock modular fixturing systems requiring a primary liner in 0.5-inch fixture plates with a 1.0018-inch receiver bore and 16mm ID.

Installation Notes

Installation is typically performed by a toolroom technician or machinist using a press or arbor to seat the liner flush and square within the fixture plate bore. Ensure the receiving bore is clean, burr-free, and within tolerance before pressing the liner into position. Do not use impact tools during installation, as this may damage the liner bore or alter dimensional integrity. Follow the fixturing system manufacturer guidelines for interference fit and plate preparation.
