Extended Length Bellows Coupling: Increased Misalignment

Ruland extended length bellows couplings have more convolutions than standard bellows styles allowing for up to double the misalignment. They are ideal for precise positioning applications that utilize a servo or stepper motor connected to a ball screw, lead screw, or gearbox. Extended length bellows couplings are available in clamp style hubs with or without keyways in inch, metric, and inch-to-metric bore combinations ranging from 3/16” to 3/4" and 4mm to 20mm. Ruland manufactures them in our ISO 9001:2015 certified advanced manufacturing facility in Massachusetts, USA. They are RoHS3, REACH, and Conflict Minerals compliant.
