Gibraltar 645260-G Revolving Handwheel Machine Handle

Product Description

The GIBRALTAR 645260-G is a revolving handwheel machine handle designed for use on industrial machinery, equipment controls, and manual adjustment applications. The handle features a bulb-shaped grip that rotates freely around a press fit stem, allowing smooth one-hand operation without repositioning the grip. The carbon steel construction provides durability under repeated use in shop and mechanical environments. The stem measures 7/16 inches in diameter and 3/4 inches in length, and the overall assembled length is 4-1/32 inches. This handle is installed by maintenance technicians, millwrights, and machine operators wherever a reliable manual control point is needed.

This handle is suited for machine tool controls, valve adjusters, jigs, fixtures, and general industrial equipment requiring manual handwheel-style operation. The press fit stem mount allows direct installation into a matching bore without additional fasteners. Typical applications include lathes, milling machines, drill presses, and similar equipment requiring a secure, easy-to-operate grip point. The bulb shape is well suited for low-torque rotary adjustments where operator comfort and control are priorities.

Installation Notes

Installation is performed by maintenance technicians or millwrights. Before installing, de-energize or lock out the machine per OSHA lockout/tagout procedures. Press the stem into a clean, correctly sized bore — verify the bore diameter matches 7/16 inches before pressing to avoid damaging the stem or housing. Do not use the handle to apply loads beyond the rated manual-operation range of the equipment it is mounted on.
