Dual purpose of miniature couplings：motion control and power transmission
How to select couplings A simple and generally used method to select the most suitable coupling is the four step approach. That is, 1. Select the coupling type suitable to the intended usage 2. Select the material of the coupling in line with the environment of usage 3. Select the coupling size fitted to the […]
High-gain rubber couplings from NBK
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 […]
ROBA-DS shaft couplings tested by DNV GL
The compact ROBA-DS disk pack couplings by mayr power transmission have been certified by DNV GL. They ensure maximum safety for users on the high seas. Whether in the drives of ship propellers, mobile platforms such as drilling platforms for oil and gas extraction, or also in tidal power plants – the areas of application […]
Shaft couplings for torque transducers
Design ROBA-DS disk pack couplings of the type series 9110 and 9210 from Mayr are especially adapted for the attachment of HBM torque transducers. Different types of construction and flexible combination possibilities permit the integration of measurement flanges in almost every test stand and drive constellation. Function ROBA-DS disk pack couplings compensate for axial, radial […]
High speed couplings for machine tool spindle applications
High speed Miki Pulley SFD Couplings are rigid, metal disc couplings featuring zero backlash and high torsional stiffness with high concentricity for precise shaft alignment in demanding machine tool spindle applications. Handling system speeds up to 20,000 RPM, they maintain concentricity within .001 TIR. The SFD couplings feature self-centering, single bolt clamping at both coupling […]
New ServoClass coupling size added to zero-max coupling line
A new ServoClass Coupling size in both single and double flex models has been added to the Zero-Max ServoClass coupling line. Providing high torsional stiffness, these ServoClass couplings are designed to handle high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications. The new size in single and double disc models handles […]
Replacement wind turbine couplings for drivetrains with capacities up to 5MW
Zero-Max Wind Turbine couplings are now available as an upgrade replacement for existing wind turbines and for OEM applications. Tested and proven under conditions simulating a 20-year load spectrum of continuous operation, Zero-Max turbine couplings handle torque spikes and high misalignment installations. Zero-Max couplings are designed with composite disk packs at both ends of a […]
Disc couplings for gas recovery compressor package
A major global gas compressor OEM needed couplings for a new gas recovery reciprocating compressor package. The multi-stage unit featured a preliminary motor-driven flash gas compressor scrubber and two motor-driven flash gas compressors. Three different couplings were required to connect each electric motor and associated compressor. The OEM contacted Bibby Turboflex based on a long […]
Bibby Turboflex HF Series disc coupling for FPSO vessel pump
A leading industrial pump manufacturer needed high-performance couplings for a topside sea water injection pump package used on-board a floating production, storage and off-loading (FPSO) ship. The massive oil and gas refining vessel, with a 2M barrel capacity, is positioned over the Egina deepwater oilfield, 150 Km off the shore of Nigeria. Couplings were required […]
