The CHF SCHS series of stainless steel ball-and-socket joint bearings are integrated ball-and-socket joint assemblies designed for precision mechanical connection applications requiring compact space, multi-degree-of-freedom flexible movement, and excellent corrosion resistance. This series integrates a precision stainless steel ball head pin with a self-lubricating ball bearing into a robust unit, providing customers in the aerospace, high-end robotics, precision instrumentation, and medical device industries in Europe and America with a high-precision, low-friction, maintenance-free, and highly reliable compact motion connection solutions.
Key Technical Features
Compact Ball-and-Socket Joint: The ball head and bearing socket form a compact, self-retaining ball-and-socket pair, providing multi-directional swing angles from ±12° to ±25°, while reducing axial dimensions by more than 30% compared to traditional rod-end bearings.
Standardized Threaded Interface: The rod end is available with metric (ISO), imperial (UNF/UNC), and special fine threads, and lock nuts and anti-loosening washers are optional to ensure reliable connections.
Stainless steel spherical plain bearing inner core: The core uses CHF GEE..ES series high-performance self-lubricating spherical plain bearings. The inner ring spherical surface is reinforced with PTFE/glass fiber lining, with a friction coefficient ≤0.05, achieving lifelong dry self-lubrication.
