Based on a compact and simple design, the ESL series torque limiters from R+W offer accurate performance at a reasonable cost. Unlike traditional ball-detent torque limiters, the ESL spring loads two series of ball bearings against one another to create a rolling effect at overload. The rolling effect reduces wear and at the same time […]

Six factors to remember about couplings in a motion system
Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]
ServoClass® Couplings deliver high torsional stiffness
ServoClass® Couplings suit applications using ac and dc servomotors that need precise positioning and the ability to handle high reverse loads. These couplings have zero-backlash and low hysteresis. Three new sizes have been added to the ServoClass coupling line. They handle bore diameters from 0.875 in. (20 mm) to 1.378 in. (35 mm) and operating […]
Schmidt 5D Couplings Handle Axial, Angular And Parallel Shaft Misalignments
Schmidt 5D Couplings suit applications requiring large axial, angular and parallel shaft misalignments. This “all-in-one” coupling design will handle all shaft displacements providing low backlash for precision high torque applications such as roll forming and similar heavy duty fabricating equipment. Designed to fill an important need in the Zero-Max family of torque-rigid couplings, these couplings […]
For safety, electronics may not be the best choice
The trend of replacing mechanical systems with electrical systems continues. Even developers of hydraulic and pneumatic systems are following it. But, as is becoming evident through the latest unintended acceleration issues, electronic components can have a few drawbacks that should not be overlooked in a design. When in comes to designing a system for safety, […]
Breakaway Connectors Allow A Quick Disconnect
ITT Interconnect Solutions offers a line of breakaway connectors. The Nemesis Series and MKJ Series breakaway connectors incorporate a simple push/pull mating mechanism to engage and disengage the connector systems. The coupling mechanism utilizes a canted spring design, which allows for a quick disconnect and ratings of more than 5000 cycles. The breakaway connectors also […]
LEM Engineers Invent Unique Magnetic Coupling Technology
LEM has introduced the first of its AC current sensor families based on Perfect Loop Technology. After calibration, the new RT series achieves absolute accuracy of better than 0,65% – including position error – making them the first split-core Rogowski coils to be suitable for use in Class 1 power devices. An imperfect coil structure […]
