In an ideal world, multiple components could be produced in a single piece, or coupled and installed in perfect alignment. However, in the real world, separate components must be brought together and connected on-site. Couplings are required to transmit rotational forces (torque) between two lengths of shaft, and despite the most rigorous attempts, alignment is […]

New Jaw Couplings Have Zero Backlash
Zero backlash jaw couplings that are three piece couplings comprised of two hubs and a plastic element are one of Ruland Manufacturing’s new products in their coupling line. The Spider, shown below, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in two […]
Machined Spring Features HELI-CAL Flexure
SANTA MARIA, CA—The HELI-CAL® Flexure is a flexible helix (curved beam) machined into a unique configuration that incorporates special design requirements, performance features and/or characteristics. The material is basically unlimited. When used as a spring, the multi-functional flexure provides desired and predictable elastic performance in compression, extension, torsion, lateral bending and lateral translation modes. One […]

New Hyde Park NY — A new series of metric Neo-Flex couplings from Advanced Antivibration Components – AAC feature excellent torsional vibration isolation plus shaft-to-shaft insulation. The center of these couplings, identified as the V50FSR-… (inch) and V50FSRM… (metric) for the Short Series, and V5DFLR-…(inch) and V5DFLRM (metric) for the Long Series, are made from […]
Silicone Insert Couplings from Sterling Instrument
New Hyde Park, NY — A new series of silicone insert couplings from Sterling Instrument (ISO 9001:2000+AS9100B Registered Manufacturer) features electrical isolation and no backlash. These metric couplings, identified as the S54HSAM… (clamp type) and S5PSAM… (set screw type) Series are stocked in 5 different bore sizes ranging from (6 mm to 16 mm). These […]
Innovative Steel Bellows Coupling Released
When first examined, steel bellows couplings seem to be the same superficially, but as one looks at the technical details, they will find there are substantial differences. The construction, structure and manufacturing quality of the steel bellows are the main factors for operational safety, reliability, service lifetime, misalignment capability and functional safety of the entire […]
How to Properly Select a Bellows Coupling
Properly selected bellows couplings result in the best control over the load in any servo application. Here are tips to ensure you choose the right size for the application. Bellows couplings help maintain tight controls over loads. For years, bellows couplings have been a mainstay for efficient motion systems because they offer high torsional stiffness, […]
Servo Torque Limiters
Protection of an electromechanical system from torque overload is often assumed to be guaranteed by the current limits set in the drive parameters. But in the case of hard stops, impacts and other situations where overload occurs very rapidly, sufficient energy to do damage often exists in the rotating inertia driving the load. R+W servo-rated […]
Oilfield Encoders Eliminate Barriers
Gurnee, IL – Dynapar announces the introduction of the EN series of oilfield encoder suitable for use in Zone 1 hazardous locations. What makes the new incremental encoders unique is their ability to operate in hazardous areas without the need for intrinsic safety (I.S.) barriers. Removal of the I.S. barrier reduces system cost, simplifies wiring, […]
Centa’s Quality Assurance Excels
CENTA is the first company worldwide to which Germanischer Lloyd (GL) has conferred the responsibility for alternative product certification of type-approved couplings. In the future, CENTA will have the authority to carry out acceptance testing and final stamping of those couplings that have previously been classified as approved types. These tests must be performed in […]
