All flexible couplings compensating for misalignment cause reaction forces, and their effect is significant if misalignment is excessive. These often-overlooked reaction forces transmit to connected shafts and support bearings, and can cause damage to motion axes — especially on precision designs with delicate bearings and slender shafts. Though couplings get their compliance from elastomeric deflection, […]

Turboflex Plus couplings for turbomachinery applications
Ameridrives and Bibby Turboflex, two international flexible coupling manufacturers, have collaborated to introduce a new series of high performance disc couplings designed to meet the stringent requirements of today’s turbomachinery market. The new Turboflex Plus couplings combine Turboflex and Ameridisc disc coupling technologies together with the experience of the Ameriflex diaphragm coupling to create a […]
Disc couplings with integrated coolant tube for spindle drives
R+W has recently expanded its LP product line with a new disc pack coupling model. In addition to the wide range of standard designs, R+W can now supply a version with an integrated coolant tube. This offers many advantages to manufacturers of machine tools with long spindle drives. This specially designed double disc spindle coupling […]
Coupling options for pump and compressor applications
When designing pumps and compressors, you’ll need to use couplings that balance efficient torque transfer against the ability to withstand vibration, shock loads and misalignment between the motor and drive shaft. Ringfeder offers four coupling options that help do just that. TNR Coupling consists of an aluminum housing and steel hub, separated by cylindrical elastomer […]
Altra couplings for Navies around the world
Modern navies are comprised of a wide variety of sophisticated vessels, including aircraft carriers, destroyers, frigates, patrol boats and submarines. With more than 105 navies in the world, advanced battleforce and support ships continue to be commissioned at a steady pace to meet multi-mission duties, including war fighting and maritime security. Recent developments in technology, […]
R+W’s LPZ short spacer added to disc coupling line
In its effort to fill in and complete its flexible disc coupling offering, R+W has added a standard coupling adapter which provides customers with more configuration and connection options when selecting couplings for industrial applications. The LPZ spacer accompanies a quickly expanding product line and offers lateral misalignment capabilities in a very small package. It […]
New ARPEX all-steel coupling from Siemens
Siemens will present an additional series in the range of torsionally rigid all-steel disc couplings: the new N-ARPEX coupling with improved performance characteristics. An optimized disc pack and a revised component design facilitate the transmission of higher torques and speeds as well as a higher bore capacity with standard hubs. All-steel couplings can be used […]
GCH couplings with locking hubs
A leading packager of reciprocating compressor equipment required a reliable coupling solution for its line of compressor packages used at natural gas vehicle (NGV) refueling stations. These stations are needed to support the growing number of natural gas powered municipal bus and truck fleets as well as passenger vehicles. The multi-stage, skid-mounted compressors feed the […]
Coupling application profile: power plant induced draft fans
A major global industrial fan OEM needed a replacement coupling solution for an induced draft fan drive at a large power plant. The fan maintains system pressure slightly below atmospheric pressure on a coal-fired boiler at the facility. The existing fan drive used an old gear coupling design which had reached the end of its […]
Turboflex HS couplings for biomass-fired steam turbines
A leading global provider of power generation technologies required coupling solutions for use on three steam turbines at a series of new biomass power plants located in the UK. The three geared reaction steam turbines include a 23 MW unit and a 45 MW unit that will be fired by waste wood, while a 50 […]
