Disk
Couplings for higher speed applications
ServoClass Couplings feature high torsional stiffness, zero backlash and low hysteresis to ensure repeatable precise positioning at speeds up to 10,000 rpm. Their robust design ensures precise system operation in automated 24/7 applications. That is especially true where stresses occur at increased speeds in a servo system. Designed with 304 stainless steel disc packs and […]
High-Torque Disk Couplings Resist Fretting
Torsiflex disk couplings are torsionally stiff and backlash-free, incorporating an anti-flail feature. The couplings also withstand significant levels of misalignment without loss of operating performance. The design drives in friction, rather than shear, to the disc coupling by using large aircraft-quality bolts on the disk hubs. As a result, the pack of blades in the […]

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 […]
Tips to simplify coupling selection
For a coupling in a servo application to work properly, you need to satisfy a number of application factors including: torque, shaft misalignment, stiffness, speed, and space requirements. Here’s a look at the available types of servo couplings and what you need to consider for each of them during the selection process. Beam couplings Beam […]
Inch & Metric Magnetic Disk Couplings
New Hyde Park, NY — A new series of magnetic disk couplings from Sterling Instrument (ISO 9001:2000+AS9100B Registered Manufacturer) features no friction or wearing parts, uses no electricity and no magnetic particles to leak. These units, identified as the S50DCM… (inch) and S50DCMM… (metric) Series are stocked in 8 different bore sizes ranging from .1875″ […]
Composite Disc Couplings for the Wind Turbine Industry
Plymouth, MN – Zero-Max, Inc.announces introduction of its Composite Disc Couplings for the wind turbine industry. “These couplings withstand extreme misalignment while remaining torsionally stiff and have passed the ‘hell hole’ test at Tehachapi, California Wind Farm,” reports James Motz, member of the Wind Team for Zero-Max. “The couplings were tested under conditions simulating a […]
High Performance from Miniature Disc Couplings
Marlborough, MA – Ruland offers miniature disc couplings both in single and double disc styles. Disc couplings are high performance motion control couplings with zero-backlash, excellent speed capabilities up to 10,000 rpm, strength and torsional stiffness characteristics, as well as low inertia for today’s highly responsive systems. Disc couplings are often used in servomotor and […]
Sliding Disc Coupling Provides Design Flexibility
The design and manufacture of customised linear positioning systems on short lead times is key to LinTech’s success. This California-based company offers an exceptionally wide range of options enabling its customers to create the optimum system for the job. To compensate for misalignment between the motor shaft and screw (or belt) drive shaft extension LinTech’s […]
