Shrink discs are rigid couplings with two external rings that tighten together axially and exert inward force on a third ring via tapered surfaces. This closes the inner ring onto the shafts and …

Choose from our selection of rigid shaft couplings in a wide range of styles and sizes. Same and Next Day Delivery.

Rigid A rigid coupling permits neither axial nor radial relative motion between the shafts of the driver and driven unit. When the two shafts are connected solidly and properly, they operate …

Rigid shaft couplings are made from a wide range of materials, including brass, 2024 aluminum, steel (carbon steel and carbon steel with a black oxide finish), and 303 and 304 stainless steel. …

A rigid coupling is a solid mechanical device used to connect two aligned shafts in a machine, ensuring zero relative movement between them. Unlike flexible couplings, which …

Rigid couplings connect two shafts that are aligned and don't allow for any relative movement between the shafts. Clamping couplings have more holding power than set screw couplings.

Sep 10, 2025 · Learn about the definition, operating principles, advantages of rigid couplings, and their industrial applications in precision machinery and automation.

Jun 13, 2025 · Rigid couplings – sometimes called rigid shaft couplings or sleeve couplings – are solid shaft connectors that join two shafts without allowing any relative motion.
