NBK America now offers the XG Series of couplings. Why? TO keep pace with the evolution of servomotors. Couplings today are a key component for helping servomotor-driven setups deliver speed-response frequencies … without the problem of vibration that usually accompanies such designs. In fact, it’s difficult to get maximum servomotor performance with high-rigidity couplings such as […]

R+W Releases STE safety coupling with elastomer connection
R+W has recently narrowed the gap between its classic precision and industrial drive safety couplings with the new STE series. Featuring the well proven technology of the ball-detent safety element system, which disconnects drivelines within milliseconds of a torque overload event, this version is more cost effective and available in smaller sizes than the standard […]
Overload protection for hard to access drives
EAS-reverse – the disengaging torque limiter with automatic re-engagement With their EAS-reverse, mayr power transmission has developed a new, disengaging torque limiter on which all functional processes can be automated through the drive. It is easy to handle, permits long run-out times and re-engages again through slow backwards rotation. A housing also makes the clutch […]
How to install a torsionally soft coupling
Edited by Mike Santora *This is an excerpt from a Design World Webinar presentation by Ed Cole of Ringfeder Power Transmission. …Our TNR series torsionally soft coupling is typically installed on the flywheel of a diesel engine. The TNR is usually installed on pump packages, compressor packages, gen-sets, other specialty packages and fire-pumps. The primary […]
Insert properties in precision grade elastomer couplings
By Joyce Laird, Contributing Editor Andy Lechner, Product Manager for R+W America, explains that it is important to look at how to break down the classifications of elastomer insert couplings to better understand how everything fits into industry use today. He says that elastomer insert couplings generally fall under one of two main classifications: “standard” […]
How does shore hardness relate to elastomer inserts in couplings?
By Joyce Laird, contributing editor Precision elastomer couplings are used for a variety of applications in which a customer may need backlash-free torque transmission, vibration damping, electrical isolation, and compensation of misalignment. These torsionally soft couplings have an adjustable stiffness and temperature range with the selection of the color coded elastomer insert or spider. Alex […]
High-damping couplings
Miki Pulley’s newly developed laminated rubber element achieves high damping and low reaction force. STEPFLEX couplings for servo stepping motors that boast high damping performance. Their unitized construction with HNBR in the power-transmitting elements provides a backlash-free design. They dampen vibration faster than flexible couplings that use metal in their elastic components. This suppresses the […]
New engine coupling offers easy stiffness adjustments
Ringfeder Power Transmission has developed a patent-pending engine coupling that optimizes torsional stiffness and misalignment tolerance across a wide torque range. This new TSCHAN TNR coupling is intended primarily for mobile and stationary diesel-driven powertrains. TSCHAN TNR Couplings consist of an aluminum housing and steel hub separated by one or two rows of mechanically-linked, cylindrical […]
Precision couplings for high speed spindle applications
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. […]
