Rigid Couplings

Rigid couplings serve as components for timing, joining, or aligning of shafts at lower speeds and torque, especially where zero backlash is desired. They are the most basic, economical, cost effective coupling option, and applicable for aligned shafts only. Taper Bore Rigid Couplings provide a convenient method of rigidly connecting ends of shafts. These couplings have a male and female flange fully machined. The male flange can have the taper bush fitted from the Hub side (H) or from the Flange side (F), the female flange always has the bush fitting (F).

This gives two possible coupling assemblies (HF) and (FF). When connecting horizontal shafts, the most convenient assembly should be chosen. When connecting vertical shafts use assembly (FF) only.
