The CFR8M/CFL8M is a metric two-piece commercial-industrial female rod end with a 8 mm bore and M8 X 1.25 internal thread, sized for light industrial linkages, automation actuators, and compact machinery. The female body threads directly onto a mating stud or tube adapter, letting the rod end serve as the pivot at the clevis end of the assembly.
Bore (B) is 8 mm with a 22.25 mm body housing diameter (D). Female body length (AF) is 36 mm, thread engagement (CF) is 17 mm, body width (W) is 12 mm, and body thickness (T) is 8.00 mm. Approximate weight is 40 g.
The CFR8M/CFL8M is rated at 15,190 N static radial load with up to ±28° of misalignment — check both figures against your assembly's actual loading and angular requirements before final selection.
The 15.88 mm ball is 52100 bearing steel, precision ground, heat treated, and hard chrome plated, running in a metal-to-metal race. The body is carbon steel with silver zinc plating for commercial-industrial corrosion resistance.
CFR8M is the right-hand thread version and CFL8M is the left-hand thread version of the same M8 X 1.25 female rod end — the two are typically ordered together as a matched RH/LH pair, or individually where only one thread hand is needed.
Yes. Adding a 'T' suffix (e.g., CFR8MT) gives a PTFE-lined, maintenance-free race in place of the standard metal-to-metal race. A studded version (add 'S' suffix) is also available, along with alternate thread pitch variants, yellow zinc plating, and alternate body materials on request — confirm the option and quantity when requesting a quote.
