Bore 0.5000 / 1/2-20 ThreadVMR8 / VML8 features a 0.5000″ bore (B) and 1.312″ body diameter (D), with a 0.937″ precision-ground 52100 steel ball running in an oil-impregnated sintered bronze race. Overall body length (AM) is 2.438″, thread engagement (CM) measures 1.500″. Width (W) is 0.625″ and body thickness (T) is 0.500″. Approximate weight: 0.250 lbs.
Rated at 6,660 lb static radial load with ±12° misalignment angle, this 3-piece male rod end with a 1/2-20 UNF 3A external thread suits suspension systems, steering linkages, and mid-range industrial applications. The sintered bronze race is oil-impregnated during manufacture, providing continuous self-lubrication without external greasing — ideal for installations where periodic maintenance access is limited.
Available in right-hand (VMR8) and left-hand (VML8) thread configurations. Grease fitting option available (add suffix Z, e.g. VMR8Z) for extended service intervals. Stud configuration also available (suffix S). Silver zinc plating available on request for enhanced corrosion protection. Body is carbon steel, heat treated and yellow zinc plated.

The VMR8 / VML8 is a 3-piece male rod end with a 0.5000" bore and 1/2-20 UNF 3A external thread, built for suspension systems, steering linkages, and mid-range industrial applications.
Bore (B) is 0.5000", body diameter (D) is 1.312", the ball is 0.937" in diameter, overall body length (AM) is 2.438", thread engagement (CM) is 1.500", width (W) is 0.625", body thickness (T) is 0.500", and approximate weight is 0.250 lbs.
The VMR8 / VML8 is rated at 6,660 lb static radial load with up to ±12° of misalignment.
The 0.937" ball is 52100 bearing steel, precision ground, heat treated, and hard chrome plated, running in a sintered bronze race that's oil-impregnated for continuous self-lubrication without external greasing. The body is carbon steel, heat treated and yellow zinc plated; silver zinc plating is available on request for added corrosion protection.
VMR8 is the right-hand thread version and VML8 is the left-hand thread version of the same male rod end — same size and load rating, opposite thread hand, typically paired for turnbuckle-style adjustable linkages or used individually for fixed installations.
SYZ offers a grease-fitting option (add suffix Z, e.g. VMR8Z) for extended service intervals, a stud configuration (suffix S), and silver zinc plating on request for enhanced corrosion protection — confirm which options you need when requesting a quote.
