Servo couplings from Ever-power can be found in a wide variety of variations, sizes, and resources to match differing application requirements. Choosing the right servo coupling could be a difficult process that involves many performance elements which include: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system effectiveness. Ever-power provides servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types permitting the user to choose the coupling that finest fits their request. All Ever-electricity couplings will be zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles in addition to a vast array of sizes and materials to suite your unique application and/or customized requirements. Maintaining optimum system performance relies on properly matching a shaft coupling based on your unique performance and application requirements and specifications. At Helical, we have used the guesswork out of picking the complete servo coupling for your application by factoring in crucial aspect dynamics such as shaft misalignment, space requirements, torque, and RPM.

Ever-powerdrive couplings are power transmission components used to couple the shafts of various mechanical devices, also to compensate for shaft misalignment, reducing stress in shafts and bearings. Beam-style couplings are made for servo applications, providing the flexibility of bellows couplings plus torsional stiffness and strength of disc couplings.
Ever-power manufactured beam couplings have excessive angular misalignment capabilities, are zero-backlash and also have a balanced style for reduced vibration in boosts to 6,000 RPM. They are manufactured from a single piece of aluminum or stainless steel with multiple sets of spiral cuts to supply higher stiffness and better all-around misalignment features than traditional one beam couplings. Ever-electric power beam couplings can be purchased in inch, metric, and inch to metric bore sizes ranging from 3/32″ to 3/4″ and 3mm to 20mm. they are commonly used in encoder, tachometer, and mild duty power transmitting applications where precise motion control is desired.
Ever-power manufactured bellows couplings have excessive torque and torsional stiffness functions, are zero-backlash, have a balanced design, and may accommodate all varieties of misalignment. They happen to be made up of two anodized aluminium hubs and a stainless steel bellows making a light-weight low inertia coupling capable of speeds up to 10,000 RPM. The thin wall of the stainless steel bellows can simply flex while leftover rigid under torsional loads. Ever-power manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with in ., metric, and inch to metric bores ranging from 1/8″ to 1 1″ and 3mm to 25mm. They are generally used in high performance stepper servo devices where precise action control is required.
Ever-power Controlflex couplings are a three-piece assembly with a balanced style comprised of two hubs joined to one or two middle inserts called frogs. This style creates a light-weight low inertia flexible coupling capable of speeds up to 25,000 RPM. Clamp style hubs are made with “, metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for excessive customizability. The unique design and style of the frog concentrates forces onto its versatile limbs enabling low bearing loads protecting sensitive little bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating since the hubs do not contact and frogs are manufactured from acetal. They happen to be made by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Ever-power created disc couplings have great torque and torsional stiffness capabilities, are zero-backlash, have a balanced design, and may accommodate all varieties of misalignment. They happen to be created in single disc models for compact installations and dual disc styles for bigger misalignment capabilities. Ever-electricity disc couplings are made up of two anodized aluminum hubs, stainless steel disc springs, and a center spacer (double disc just) creating a light and portable low inertia coupling with the capacity of boosts to 10,000 RPM. Hubs are made with or without keyways in clamp and arranged screw styles with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in high performance stepper servo systems where precise movement control is required.
Ever-power made zero-backlash jaw couplings possess a highly customizable three-piece style, have high dampening features, and can accommodate all kinds of misalignment. The two lightweight aluminum hubs press match onto an elastomeric centre spacer referred to as “the spider” allowing for steady zero-backlash operation. Ever-vitality zero-backlash jaw couplings possess a balanced style for decreased vibration at speeds up to 8,000 RPM. Hubs are made with or without keyways in clamp or set screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be found in three durometers allowing the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are commonly found in applications with excessive acceleration/deceleration curves where dampening and exact movement control are required.
Ever-power created oldham couplings have an extremely customizable three-piece design, are zero-backlash, and also have high parallel misalignment capabilities. Two anodized aluminum hubs press fit into the mating slot machines of the guts disk allowing for zero-backlash operation and low bearing loads. Ever-electrical power oldham couplings have a balanced style for lowered vibration at speeds up to 4,500 RPM. Hubs are made with or without keyways in clamp or set screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks are available in three materials allowing the user to complement coupling performance with program requirements. They are generally found in stepper servo devices that require a higher parallel misalignment coupling.
Ever-electricity slit couplings will be an alloy, one piece configuration designed to provide smooth tranny of motion, great torsional stiffness, low bearing loads, and extended life. The slot structure provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two sets of identical slot machines, the mini slit coupling is definitely constant velocity by design and handles angular, parallel and axial offset. Obtainable in 6 and 8 mm diameters and allowable boosts to 70,000 rpm, slit couplings are a reliable one part coupling design that techniques the performance of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly found in all varieties of machinery that accomplish the various processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as bearings, which can cause early failing of both.
o Shaft ends could be misaligned radially or perhaps angularly, exhibit axial displacement, or experience a blend of all three.
o Drive couplings works extremely well to pay for shaft misalignment, if the misalignment is an intentional or an unintentional area of the design.
