In an effort to address increased demand for its SERVOMAX elastomer couplings in high speed spindle applications, R+W Coupling Technology has released its new SP6. Made with improved concentricity and perpendicularity, and higher grade materials, the hubs are capable of handling circumferential speeds of up to 80 m/s, and higher torque levels per size. The […]

Changing gears: elastomeric couplings shift focus to simplicity
By Matt Bamford, Tyler Coffey and Johannah Nelson, The Timken Company Edited by Mike Santora While inconspicuous, couplings have long been essential for facilitating the transfer of power within machines and equipment. Gear couplings, a type of flexible coupling, are particularly popular in industrial applications where they transmit high torque loads and tolerate moderate misalignment. […]
Easy to install EDC elastomer drive shaft coupling
GAM, a manufacturer of precision gear reducers, couplings, and linear mounting kits, has introduced the EDC Elastomer Drive Shaft Coupling product line. The EDC is the latest addition to GAM’s family of zero backlash drive shaft couplings. Offered in four sizes with torque ratings up to 110Nm, the EDC is available in standard lengths up […]
What do you know about Elastomeric Couplings?
Elastomeric couplings are a form of flexible coupling that uses an insert made of an elastomeric polymer to help transmit torque. The design of elastomeric couplings means that the elastic material is meant to wear out before any metal components. This not only saves time and money on maintenance but also means that the couplings […]
Step-Flex couplings reduce resonance in stepper motor ball screw assemblies
Mechanical resonance in motion systems can cause, not only unpleasant noise, but can lead to oscillations in the machine that reduce the positional accuracy of the system. This oscillation can also cause the system to take too long to find its correct positioning and further degrade performance. In rare cases where extreme oscillation is present, […]
Shaft Coupling Solves Resonance Problems in Ball Screws
Miki Pulley has introduced its Step-Flex Coupling for direct sale to OEM’s in North America. The Step-Flex is an altogether new class of shaft coupling. This design was conceived to eliminate resonance in stepper motor ball screw assemblies. The two part elastomer element combination dampens vibration caused by the actuator carrier struggling to find its […]
Elastomeric couplings stabilize hydraulic fracturing pumps
Extracting natural gas from underground shale formations is done via high-pressure pumping equipment that injects a specialized mixture of water, sand and chemical additives into vertical, horizontal or multi-lateral well bores. These high pressures can lead to vibration and other damage to the truck-mounted hydraulic fracturing pump units. A major manufacturer needed reliable couplings for […]
Intermediate Coupling Spacers
SERVOMAX elastomer couplings feature a specially calibrated polyurethane insert, which is preloaded between precision machined driving jaws. They have high torque density, are low in cost, and are used for vibration damping, shock absorption, and compensation for some small amounts of shaft misalignment. Occasionally, machine layouts and mounting arrangements simply do not allow for installers […]
Compact safety coupling
Making use of the existing EKL line of compact elastomer couplings, the SLE safety coupling offers a compact, flexible and vibration damping option with integral torque overload release. Designed for aggressive servo driven applications, the SLE is backlash free, relying on preloads and frictional connections, along with a precision molded, wear resistant, polyurethane insert to […]
Zero Backlash Coupling Ideal for Belt Driven Linear Actuators
Due to greater demands in modern machine design and construction, R+W has developed its EK7 series of SERVOMAX Zero Backlash Elastomer Couplings. This coupling was specifically designed to mount to hollow bores with an expanding tapered clamping element, making it ideal for belt driven linear actuators. The EK7 provides design engineers with a number of […]
