Gibraltar 645220-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR 645220-G is a fixed handwheel machine handle designed for manual control applications in industrial and mechanical equipment. The handle features a bulb shape for a secure, ergonomic grip and mounts via a press fit stem connection. The stem is carbon steel, measuring 11/16 inches in length, and the overall assembly length (OAL) is 3-29/32 inches. The stem bore accepts a 7/16 inch press fit shaft. This handle is suited for machinists, maintenance technicians, and equipment assemblers working on lathes, milling machines, jigs, fixtures, and similar machinery.

This handle is used in industrial machine tool environments where a fixed, non-folding handwheel grip is required. Common applications include manual feed controls, adjustment knobs, and positioning handles on machine tools and mechanical assemblies. The press fit stem mount simplifies installation without requiring threaded fasteners, making it a direct drop-in for compatible shaft diameters in production and maintenance settings.

Key Features

• Press fit stem mount accepts a 7/16 inch shaft diameter for tool-free installation
• Bulb shape handle design provides a secure and comfortable grip during manual operation
• Carbon steel construction on both the handle and stem for durability in industrial environments
• 11/16 inch stem length with a 3-29/32 inch overall assembly length

Compatibility

Designed as an OEM-style replacement or direct-fit handle for machine tools and mechanical equipment requiring a 7/16 inch press fit stem mount with a fixed handwheel configuration.

Installation Notes

Installation is performed by maintenance technicians or machinists. Power down and de-energize the equipment before removing or installing any handle components. The press fit stem should be seated firmly onto the mating shaft using appropriate pressing tools — do not use the handle itself as a driving surface. Verify shaft diameter and fit tolerance before installation to ensure a secure, wobble-free connection.
