Jergens 29017 Shoulder Tooling Ball 1 in Stainless Steel

Product Description

The JERGENS 29017 is a shoulder-style checking tooling ball designed for precision fixture and gauging applications in industrial and manufacturing environments. Built from heat-treated stainless steel, this tooling ball features a 1.0000-inch ball diameter held to a tolerance of plus or minus 0.0005 inches, a 0.4997-inch shank diameter with a close tolerance of +0.0000 / -0.0002 inches, and a ball-to-shank concentricity of 0.0002 inches. The shoulder, breakaway, and tapped shank features make it suitable for repeatable locating and inspection setups. Machinists, toolmakers, and metrology technicians typically install this component.

This tooling ball is used in checking fixtures, CMM setups, and precision jig assemblies where accurate and repeatable ball positioning is required. The shoulder design seats against a mating surface to establish a consistent reference datum, with the ball center located 0.7000 inches above the shoulder bottom and 1.6200 inches above the shank bottom. The breakaway feature and tapped shank allow secure mounting and controlled removal without damage to the fixture. Applications are common in automotive, aerospace, and general precision machining environments.

Key Features

• 1.0000-inch ball diameter with a ball tolerance of 0.0005 inches for precise reference points
• 0.4997-inch shank diameter machined to +0.0000 / -0.0002 inches for tight locating fits
• Ball and shank concentricity held to 0.0002 inches
• Shoulder design with 0.7000-inch ball center to shoulder bottom distance for repeatable seating
• Breakaway and tapped shank features for secure, damage-free installation and removal
• Heat-treated stainless steel construction for durability and corrosion resistance

Compatibility

Designed as an OEM-style replacement or direct-use component for checking fixtures and precision gauging assemblies requiring a 0.4997-inch shank diameter shoulder tooling ball.

Installation Notes

Installation is typically performed by a toolmaker or metrology technician. Ensure the mating bore and seating surface are clean and free of burrs before installing the shank. Do not exceed the rated engagement depth for the tapped shank, and use appropriate torque for any fasteners without over-tightening. Verify concentricity and seating with a dial indicator after installation to confirm datum integrity.
