  • Motor Couplings: The Automotive Industry

    Bellows Couplings The industry that utilizes shaft couplings the most is one that captivated imaginations during its early years and now has woven its way onto the necessity list of every company and individual. Manufacturers of automobiles use motor couplings in every vehicle made, whether it is for the residential market or one of the many industrial ones. Shipping companies require trucks as do most manufacturing factories. The marine industry utilizes the same sort of motor couplings for boats as do aerospace and aviation crafts. Therefore motor coupling models are...

  • Bellows Couplings: The Flexible Design

    There is much to be said for a flexible design, particularly when it is a part that is meant to allow movement on multiple axes. The bellows coupling is a shaft coupling that has three major purposes, all of which it accomplishes well. First, all couplings are connectors, making two pieces one when one of the pieces is rotary equipment and the other is a stationary piece of a system. The bellows coupling is no exception. Most shaft couplings are meant to allow movement of the rotary equipment, why they...

Bellows Couplings

Bellows couplings are connectors for shafts and equipment that require flexibility and non-linear alignment. These devices are composed of a rigid bellow and a coupling that transmits mechanical power between shafts, maintains constant velocity and compensates for axial motion and parallel or angular misalignment. Typically the bellows are made from stainless steel which is an excellent transmitter of torque. The coupling is made of aluminum which makes these devices exceptionally lightweight and durable. Bronze is also sometimes used. The walls are thin enough to allow the coupling to flex while remaining relatively rigid.

Bellows couplings are cylindrical with flexible rings acting as the coupling. On either side are solid metal ends that connect to shafts or other components. They are typically quite short in length and range in diameter size from 1/8 inch to a full inch; custom or specialty sizes are available but do not greatly vary in construction or function. Like shaftwheel couplings they are constructed to reduce vibration when used in applications with high rotations per minute (rpm). Mostly used in industrial machinery, bellows couplings create a quiet, smooth operation in systems with high levels of torsional integrity like encoder drives, closed loop servo systems, motion control instrumentation, robotics, CNC machine tools and precision positioning.


Mechanical flexible couplings are made of loose fitting parts that move in a sliding and rolling manner; bellows couplings fit this category because they have a coil that allows them to move. Unlike other mechanical flexible shaft couplings, these generally need no lubrication. They offer a near-infinite life span and are virtually maintenance free. Their connection is hidden within the fit-length of the hub, enabling exact transmission of angular motion and torque. Bellows couplings operate at high speeds anywhere from 12,000 to 32,000 rpm and absorb eccentricity and angularity. They are oil- and chemical-resistant, have thin and lightweight yet strong walls and offer easy and simple mounting and dismounting. Bellows couplings exhibit high torsional stiffness and zero backlash. The most common methods of construction for flexible couplings such as these include electroforming, chemical deposition, mechanical forming and welding.  Electroformed bellows couplings are made by adding layers of metal on a mandrel until the desired thickness is reached and the mandrel is melted away to leave behind the bellows. Chemical deposition is a similar method except that the materials are added by electrodeposition. Mechanical forming includes roll-forming or extrusion. Welded bellows couplings are made by welding a series of rings or washers on both their inside and outside.
