Ball Joint Sleeve

The Ball Joint Sleeve from U-B Machine is a precision-engineered fastening component designed for demanding tactical, military, and industrial applications where reliable articulation and load-bearing capability are non-negotiable. This screw-in ball joint sleeve serves as a critical connector in firearm assemblies, vehicle suspension systems, and equipment mounting solutions where controlled movement and structural integrity must coexist. Whether you're building a custom rifle platform, maintaining field equipment, or engineering a complex mechanical assembly, this component provides the durability and dimensional consistency professionals demand.

Manufactured from hardened steel with a natural finish, the Ball Joint Sleeve measures 1 inch in length and features a threaded screw-in design that ensures secure, repeatable installation without drift or play under operational stress. The natural steel construction resists corrosion in most environments while allowing for refinishing or coating application to meet specific mission requirements. At 0.32 lbs, the compact profile (2.85 x 1.45 x 3.85 inches) permits integration into tight assembly spaces without sacrificing load capacity, making it ideal for modular systems where space efficiency directly impacts performance and weight distribution.

Law enforcement armorers, military gunsmiths, and equipment technicians rely on U-B Machine ball joint sleeves for upper and lower receiver assemblies, adjustable stock mechanisms, and precision mounting applications where tolerance stack-up must remain within critical limits. Installation is straightforward—the screw-in design threads directly into compatible mounting holes, eliminating the need for separate fasteners or specialized tools. Verify thread pitch and bore diameter compatibility with your specific assembly before ordering; this component is sold individually, allowing you to source exactly what your build requires without excess inventory.
