Ruland Manufacturing Co. Inc. and Belden Inc. have started a joint venture in Europe. The company, PTMotion GmbH, has been operational since September 2009, and is headquartered in Berlin, Germany. The new company is headed by Managing Director Ralf Gabriel, a long-time sales engineer for Belden in Germany. He is assisted by Sales Engineer Sebastian […]
GERWAH Product Line
The GERWAH line of products consists of magnetic couplings, metal bellows couplings, servo-insert couplings, line shafts, RING-flex couplings and safety couplings. These couplings are available in a range of sizes and torque capacities to 3,800 lb-ft. The low mass of the lightweight construction helps increase machine performance and reduce energy costs. Ringfeder Power Transmission USA […]
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 […]
Shaft collars and couplings for solar power installations
Ruland Manufacturing Co., Inc. offers a selection of shaft collars and couplings for use in solar power generation installations. Specifically designed for harsh environments, these shaft collars and couplings handle the high temperature, salt spray, wind, moisture and airborne contaminants found around solar power generation facilities. Collars are available in a variety of zinc-plated steel, […]
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 […]
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 […]
