All couplings transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease of installation, robustness, and cost. For power transmission (as in motors for […]

Zero-Max announces new website
Select, configure and view the exact Zero-Max coupling, torque limiter, variable speed mechanical drive, overhung load adaptor and shaft locking bushing from www.zero-max.com. This newly launched Zero-Max website gives designers the exact 2D and 3D CAD drawing of the product they need that are “designed in” and ready for purchase. Site users will have access […]
Zero-Max ETP-EXPAND for pump drives
Connecting a rotating piston lobe to a hollow shaft has been improved using the ETP-EXPAND, a patented bushing device that is fast and easy to install and adjust. The ETP-EXPAND was developed to simplify exchanging seals in pumps when fluid viscosity is changed. This is often required in pharmaceutical, chemical, food and beverage processing systems […]
Servoclass couplings feature fail safe clamping hubs
ServoClass couplings from Zero-Max feature fail safe clamping hubs that provide maximum torque transmission in high speed applications. Without the use of keyways, ServoClass couplings are designed, manufactured and tested to provide shaft engagement in servo motor applications at speeds up to 10,000 rpm. ServoClass design features include precise 304 stainless steel disc members. These […]
Zero-Max CD Couplings add Electrical Insulation Protection to Mechanical Components
Motion system designers have a new option to arrest electrical current. In addition to their primary function, Zero-Max CD couplings are designed with composite flex elements that are non-conductive. The flex element designed into the couplings provides electrical insulation while protecting mechanical components from system overloads. CD Couplings do not pass electrical current through the […]
Couplings make the big-time
Who knew that something so small could make such a big difference in complex applications? We did, that’s who. Couplings—from bellows to jaw and Oldham to disc—are used in almost every motion control application to manage misalignment while transmitting torque from one shaft to another. They are often considered a commodity product but are too […]
A look at coupling selection tools
I often think of how the Internet has changed our lives, and how it has made it so much simpler in many ways. For example, buying a rare item meant either hoping your local store had it in stock or paging through catalogs. Going on a trip used to mean highlighting a route on a […]
Zero-Max offers Overload Safety Couplings
Overload safety couplings from Zero-Max are available in special models designed for washdown applications. They clean up easily, won’t corrode, and operate in a wide temperature range. Providing torque limiting and coupling functions in a single, compact unit, these Torq-Tender™ overload safety couplings serve both as a safety device and as a coupling in a […]
Zero-Max’s Clamp Style Hub Design For Handling Larger Shafts And Higher Torque
Zero-Max ServoClass® couplings now feature improved clamp style hub design for handling larger shafts and higher torque. ServoClass couplings are designed for high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications at speeds up to 10,000 rpm. The new clamp style hubs provide superior shaft engagement for these high speed applications. […]
ZERO-MAX ServoClass® added single and double disc coupling sizes
A Single and Double Disc coupling size has been added to the Zero-Max ServoClass® coupling line. The addition of the SD025R and SC025R models handle 5 to 14 mm bore diameters and torque up to 4 Nm. The new size gives designers even more options when planning their systems. Providing high torsional stiffness, these model […]
