The Hybrid Connector integrates fluidics and electronics into a single connection point. Combining dual flow paths into an integral hose assembly eliminates the need for multiple connections and simplifies the user interface between modular tools, umbilicals or hand pieces and a device. Integrating high-cycle electrical contacts directly into the connector eliminates the need for a […]

Elastomer couplings with higher torque handling capacity
The growing popularity of curved jaw (elastomer) style couplings for precision applications has driven the need for couplings that handle more than the traditional torque capacity of 2,150 Nm up to a maximum torque of 25,000 Nm. Available with split clamping collars or keyway and set screw connections, the three new body sizes allow for […]
Low Inertia Aluminum Couplings Reduce Cycle Time
The aluminum CD® model is a low inertia, lightweight coupling with high torsional stiffness for servo motor applications. It is available in single and double flex versions. “We surveyed design engineers to find out what was the most desirable feature when specifying couplings for servo motor applications,” reports Robert Mainz, Zero-Max sales manager. “Low inertia […]

6 ways to assess torque needs for safety couplings
Safety couplings that operate on the ball detent principle primarily suit disengagement torque applications. But, with some modification, they can suit highly dynamic applications with resonant frequencies and torsional rigidity. Here is a brief examination of common equations used to calculate the following torques for safety coupling design in a drive system: disengagement torque, acceleration […]
Compact Precision Torque Limiters from R+W America
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 […]
