Jergens 49511 Receiver Bushing 20mm Id Ball Lock

Product Description

The JERGENS 49511 is a reverse mount modular fixturing receiver bushing designed for use with Ball Lock system-compatible workholding setups. With a 20mm inside diameter and a 1.095-inch outside diameter, this bushing provides a precise, repeatable locating interface for modular fixturing applications. The overall height is 0.673 inches, and the bushing requires a minimum base plate thickness of 0.88 inches. It is installed by machinists and tooling technicians setting up pallet-style or modular fixture systems on CNC machine tools. The reverse mount configuration allows the bushing to be seated from the underside of the base plate, keeping the work surface clear.

This receiver bushing is used in modular fixturing environments where quick-change tooling and repeatable part location are required. It is suited for machine shops running production or high-mix low-volume work where consistent fixture registration is critical. The Ball Lock compatibility means it pairs with standard Ball Lock shanks and clamping hardware common in CNC milling and machining center applications. The 20mm clamp shank diameter is matched to the inside diameter for a precise fit.

Key Features

• Ball Lock system-compatible for repeatable modular fixturing
• Reverse mount design keeps the base plate work surface unobstructed
• 20mm inside diameter matched to 20mm clamp shank diameter
• 1.095-inch outside diameter for stable base plate installation
• 0.673-inch overall height for low-profile fixture stack-ups
• Requires minimum base plate thickness of 0.88 inches

Compatibility

Compatible with Ball Lock system workholding components using a 20mm clamp shank diameter. Designed as a reverse mount receiver bushing for modular fixturing base plates with a minimum thickness of 0.88 inches.

Installation Notes

Installation is performed by qualified tooling or machine shop personnel. Power down and lock out the machine before installing or removing fixturing components. The bushing is pressed or secured into the base plate from the reverse side, so verify base plate thickness meets the 0.88-inch minimum before installation. Follow the fixture system manufacturer guidelines for proper seating and retention.
