Constant speed couplings improve registration and system accuracy when machine function requires driven shaft offsets. Using Schmidt Offset Couplings from Zero-Max, these couplings provide machine designers with a proven method to ensure constant speed at both ends of the coupling connection and accurate machine registration. Where precision alignment of system components is required and reduced […]
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 […]
New smart-lock set saves time, space

With minimal installation labor required, Smart-Lock reduces spare part inventory costs up to 70%. This model also has indestructible, tension-optimized shrink discs for guaranteed safety. Smart-Lock provides large dimensional tolerances up to 0.2 mm […]
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 […]
What are some types of coupling shaft connections?
By Joyce Laird, contributing editor All couplings relate to the connection method between the coupling hub and mating shaft. Mike Parzych, Product Marketing Manager for GAM explains that within this area, there are many things to consider when selecting the proper mating connections. “Keyed couplings have a key slot machined into the hub that accepts […]
Proper coupling selection: What you need to know
Selecting the couplings for your motion system doesn’t exactly stretch the limits of your engineering degree. Which is exactly why most of us don’t dig deeper to see if we’re making the best choice. The following is from a presentation on coupling selection best practices from two leading industry experts. Randy Kingsbury, Vice President of […]
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 […]
Wind turbine torque limiters protect against peak loads
Zero-Max Wind Turbine Torque Limiters protect wind turbine gearboxes and generators against peak loads, reversing torques, and grid short events. They are suitable as an upgrade replacement for existing wind turbines and for OEM applications. The Zero Max torque limiter is engineered to mount directly to the generator shaft to avoid resonance concerns allowing for […]
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 […]
How do you specify keyways?
By Joyce Laird, Contributing Editor Overview Andy Lechner, Product Manager for R+W America is an expert in this field. He explains that for specifying keyways, it must be noted that there are very well established standards for dimensions, which can be found in Machinery’s Handbook, or ANSI B17.1 for imperial dimensions and DIN 6885 for […]
