Built with a cast iron body, this chuck measures 5 inches in diameter and mounts via a plain back configuration. It supports a maximum spindle speed of 3,200 RPM and offers a through-hole diameter of 1.2598 inches. Axial runout is rated at 0.0008 inches and radial runout at 0.0012 inches, making it suitable for close-tolerance turning work. Licensed machinists and lathe operators install this chuck in production and job-shop environments where repeatable jaw centering is required.\u003c\/p\u003e\u003cp\u003eThis chuck is intended for use on manual engine lathes in light industrial, toolroom, and production machining settings. The plain back mount requires a separate adapter plate or backplate matched to the specific lathe spindle nose. Reversible jaws extend workholding flexibility, accommodating both outside-diameter and inside-diameter gripping without a jaw change. The minimum jaw capacity is 1\/8 inch and the maximum jaw capacity is 4-59\/64 inches, covering a wide range of round and hex stock diameters common in general turning work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-centering 3-jaw design for fast, repeatable workpiece location\u003c\/li\u003e\n\u003cli\u003eReversible jaws support both OD and ID clamping configurations\u003c\/li\u003e\n\u003cli\u003eCast iron body provides rigidity and vibration damping during cuts\u003c\/li\u003e\n\u003cli\u003eAxial runout of 0.0008 inches and radial runout of 0.0012 inches for close-tolerance applications\u003c\/li\u003e\n\u003cli\u003ePlain back mount adapts to a wide range of lathe spindle configurations via backplate\u003c\/li\u003e\n\u003cli\u003eThrough-hole diameter of 1.2598 inches accommodates bar stock feeding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a plain back mount lathe chuck suitable for engine lathes that accept a 5-inch chuck with a separately sourced adapter backplate matched to the lathe spindle nose.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or lathe operator. Power down and lock out the lathe before mounting or removing any chuck. A proper backplate must be precision-bored and faced to match the lathe spindle nose before this chuck can be mounted.
