Bellows couplings from Ruland combine stainless steel bellows and aluminum hubs for a lightweight, low-inertia coupling. Their balanced design reduces vibration in high-rpm applications of up to 10,000 rpm. Due to the uniform thin walls, the coupling can flex easily while remaining rigid under torsional loads, and provides low bearing loads that remain constant at all points of rotation. The coupling is offered in six sizes with set screw or Nomar clamp-style hubs and straight or step bores ranging from 1/8 in. to 1 in. and from 3 mm to 25 mm. The couplings are especially suited for high-end servo, stepper, encoder and positioning applications.
