Overview
UNIBALL CUPS Product Overview
UBC8 is a 4130 chromoly uniball cup with 1.0000″ bore (B), 1.250″ OD (D), and 0.750″ width (W). Fits bearings: COM8, FKS8, COM8-SS. Includes snap ring retainer.
The UBC uniball cup is machined from 4130 chromoly steel and accepts a standard COM or WPB spherical bearing, retained by a snap ring. Weld or press the cup into a tube end or housing bore, then insert the spherical bearing to create a compact, pivoting end joint. Used in suspension link ends, panhard bars, sway bar links, and custom pivot assemblies where a welded uniball end is preferable to a threaded rod end.
Snap ring included. Mild steel cup available on request. Compatible with: COM8, FKS8, COM8-SS spherical bearings. FKS series chromoly bearings also compatible in matching bore sizes.
