Key benefits Durable stainless steel construction provides corrosion resistance and long service life in demanding environments. Large 50 mm ball diameter offers a stable, smooth pivot point for reliable mounting and alignment. Through hole with 5 mm aperture enables secure fastening with compatible hardware. Thread depth is half the ball diameter, offering balanced engagement and compatibility with mounting threads. For a 50 mm ball, the thread depth is 25 mm. Simple, singlepiece unit with clear, defined specifications. Specifications Material: Stainless steel Ball diameter: 50 mm Aperture size: 5 mm Thread depth: half of the ball diameter (25 mm for a 50 mm ball) Quantity: 1 piece Aperture classification: 5 mm to 22 mm aperture size, half thread depth Usage note: This item is listed as 50 mm ball with 5 mm aperture; the product family supports 5–22 mm aperture sizes with halfthreaddepth design Use scenarios Fixture and jig alignment: Use as a pivot point in fixtures requiring a precise spherical contact and a 5 mm throughhole for secure fasteners. Mechanical linkage replacement: worn components in equipment that uses a 50 mm ball with a 5 mm aperture to restore smooth motion and alignment. Outdoor or washdown environments: Stainless steel construction provides resistance to corrosion, making it suitable for outdoor, marine, or wetarea applications where a robust ball with a throughhole is needed. Notes Thread depth is defined as half of the ball diameter. For a 50 mm ball, the thread depth is 25 mm. This listing specifies a 5 mm aperture; other available options in the family include 5–22 mm aperture sizes with halfthreaddepth.
