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

Ruland manufactures a complete line of rigid shaft couplings. One and two-piece rigid couplings, in inch & metric, with & without keyways, straight or step bores, in aluminum, carbon steel, stainless steel.

Jan 20, 2021 · Bellows couplings are flexible coupling with twin coupling ends called hubs. These couplings have excellent torsional rigidity to accurately transmit velocity, angular position, and torque.

Explore our rigid shaft couplings and adapters - We manufacture and distribute a broad selection of rigid shaft couplings for industrial and consumer products.

Jan 10, 2023 · Rigid couplings are the most basic but often the most cost-effective types of couplings. These couplings are used to connect two aligned shafts at their ends to transmit power.

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

Rigid couplings provide solid, inflexible connections between shafts to ensure precise torque transmission without backlash. Ideal for applications requiring high stiffness and alignment.

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.

What is a Rigid Coupling? 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 …

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 provides a …
