What is couplingflexible
Flexible Shaft Couplings
Shaft misalignment can limit a machine’s performance, cause excessive vibration, high reaction loads, and accelerated wear, and often leads to premature equipment failure. Flexible Shaft Couplings can help prevent these issues by transmitting torque while compensating for parallel, angular, and axial misalignment between drive components. When installed correctly, flexible shaft couplings can also reduce vibration, minimize noise, and protect driveshaft components.
High-Performance Flexible Shaft Couplings from the Industry Leader
Zero-Max is an industry-leading Flexible Shaft Coupling manufacturer. Our zero-backlash Flexible Shaft Couplings handle large shaft misalignments without causing high radial stress and perform better than other flexible or rigid coupling alternatives in high-performance applications. Passion and quality, along with decades of experience and expertise, went into designing each of our shaft coupling lines. The results are components that deliver:
Clamp-Style Control-Flex Couplings
Clamp-style couplings attach an encoder shaft to another rotating shaft to transfer rotation between the shafts in a precise manner. They also reduce wear and tear on bearings that can lead to costly maintenance and reduced life of your encoder. Using Control-Flex couplings will help extend the operational life of your encoder and guarantee accuracy.
Clamp Style Flex Coupling Features
The construction of a Control-Flex Coupling consists of two hubs (that attach to the shafts) and a center flex member. This flexible element is affixed to the hubs through pins. Clamp-style hubs provide a positive, secure shaft connection. The clamp-style Control-Flex Couplings are available with a single flex disc for standard torque capacity, or with two flex discs for increased torque capacity, torsional stiffness, and length.
Specification range for double disc couplings
- maximum parallel shaft misalignments of 0.009” to 0.037”
- maximum peak torque of 10 in-lbs to 650 in-lbs
- maximum speed of 4,000 to 10,000 RPM
Specification range for single disc couplings
- maximum parallel shaft misalignments of 0.013” to 0.055”
- maximum peak torque of 6 in-lbs. to 361 in-lbs.
- maximum speed of 5,000 to 12,000 RPM
The clamp-style hub models come standard without keyways. Keyways and special modifications are available upon request. View the individual product specifications below for additional information.
Bolted-Style Control-Flex Couplings
Bolted-style flexible couplings transfer rotation between two shafts in a precise manner. They also reduce wear and tear on bearings that can lead to costly maintenance and reduced life of your encoder. A bolted-style coupling allows for larger shaft misalignments than clamp style couplings and can handle larger shafts and higher torques. Using Control-Flex Couplings will help extend the operational life of your encoder and guarantee accuracy.
Bolted-Style Flex Coupling Features
The construction of a Control-Flex Coupling consists of two hubs (that attach to the shafts) and a center flex member. This flexible element is affixed to the hubs through shoulder bolts. The bolted-style hubs incorporate a keyway and setscrew shaft attachment. Flex discs are bolted for drop-out capability, for easy installation and maintenance. This unique design means the reaction forces due to transmission of torque and unavoidable shaft misalignments are considerably smaller when compared with common flexible couplings.
Zero-Max bolted-style Control-Flex® Couplings were designed for encoder and instrumentation type applications. We offer couplings in four sizes that allow for maximum parallel shaft misalignments from 0.055” to 0.139,” maximum peak torques from 361 to 5,638 in-lbs., and maximum speeds from 2,500 to 6,300 RPM.

Schmidt Flexible Couplings
Schmidt Inline Couplings – L400 Series
Schmidt Inline Couplings are a torque-rigid type, designed with two pairs of parallel links installed 90 degrees out of phase with each other. This linkage arrangement allows for the precise transmission of torque and constant angular velocity between shafts with small to moderate parallel misalignments. The coupling utilizes needle bearings which can be preloaded for Low and Ultra Low backlash conditions. Where backlash is not as critical, non-lubricated filament wound Teflon® bearings are available for higher torque capacity and where relubrication of the coupling is difficult.
Typical applications which benefit from the high accuracy provided by Schmidt Inline Couplings are feeders, embossers, compactors, printing presses and many others.
Schmidt Inline Couplings are available for a torque range from 500 to 35,000 inch-pounds. Couplings for higher torque requirements are made available on special orders.
