Ruland now offers miniature rigid couplings with bore sizes as small as 3 mm. Miniature rigid couplings are suitable for micro component applications where misalignment is neither present nor desired, including connecting line-shafts, attaching a motor to a gearbox, and servo applications. Offering high torque capacity, stiffness and zero backlash, Ruland’s rigid couplings are increasingly […]

Pneumatic Torque Limiter Provides Overload Protection
Nexen announced their TL Series pneumatically engaged, single-position torque limiters, delivering overload protection for industrial machinery. The TL Series uses a ball/detent interface and proximity sensor to immediately disengage the machine shaft when excessive torque or a machine jam occurs, effectively protecting downstream equipment and product from damage and decreasing downtime. Upon detecting the overload […]
Innovative Steel Bellows Coupling Released
When first examined, steel bellows couplings seem to be the same superficially, but as one looks at the technical details, they will find there are substantial differences. The construction, structure and manufacturing quality of the steel bellows are the main factors for operational safety, reliability, service lifetime, misalignment capability and functional safety of the entire […]
How to Properly Select a Bellows Coupling
Properly selected bellows couplings result in the best control over the load in any servo application. Here are tips to ensure you choose the right size for the application. Bellows couplings help maintain tight controls over loads. For years, bellows couplings have been a mainstay for efficient motion systems because they offer high torsional stiffness, […]
Servo Torque Limiters
Protection of an electromechanical system from torque overload is often assumed to be guaranteed by the current limits set in the drive parameters. But in the case of hard stops, impacts and other situations where overload occurs very rapidly, sufficient energy to do damage often exists in the rotating inertia driving the load. R+W servo-rated […]
