Beam Couplings
Ever-power manufactured beam couplings have large angular misalignment capabilities, are zero-backlash and also have a balanced style for reduced vibration by boosts to 6,000 RPM. They are created from a single piece of aluminum or stainless steel with multiple models of spiral cuts to provide larger stiffness and better all-around misalignment features than traditional sole beam couplings. Ever-ability beam couplings can be purchased in inch, metric, and inch to metric bore sizes which range from 3/32″ to 3/4″ and 3mm to 20mm. they are commonly used in encoder, tachometer, and light duty power transmitting applications where precise movement control is desired.
Bellows Couplings
Ever-power made bellows couplings have high torque and torsional stiffness functions, are zero-backlash, possess a balanced design, and will accommodate all varieties of misalignment. They will be made up of two anodized aluminium hubs and a stainless steel bellows making a compact low inertia coupling capable of speeds up to 10,000 RPM. The thin wall structure of the stainless steel bellows may easily flex while remaining rigid under torsional loads. Ever-electricity manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with “, metric, and inches to metric bores which range from 1/8″ to 1 1” and 3mm to 25mm. They are generally used in high performance stepper servo devices where precise motion control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-piece assembly with a balanced design made up of two hubs joined to 1 or two center inserts called frogs. This design creates a light-weight low inertia adaptable coupling capable of boosts to 25,000 RPM. Clamp style hubs are produced with inches, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for substantial customizability. The unique style of the frog concentrates forces onto its flexible limbs enabling low bearing loads guarding sensitive tiny bearings in applications such as for example encoders or tachometers. Controlflex couplings happen to be also electrically isolating because the hubs do not feel and frogs are made of acetal. They are made by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power manufactured disc couplings have great torque and torsional stiffness capacities, are zero-backlash, possess a balanced design, and can accommodate all varieties of misalignment. They will be produced in single disc types for small installations and double disc styles for bigger misalignment capabilities. Ever-ability disc couplings are comprised of two anodized aluminium hubs, stainless disc springs, and a centre spacer (double disc just) creating a light and portable low inertia coupling capable of speeds up to 10,000 RPM. Hubs are made with or without keyways in clamp and set screw models with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo systems where precise action control is required.
Jaw Couplings
Ever-power created zero-backlash jaw couplings possess a highly customizable three-piece design, have high dampening features, and can accommodate all types of misalignment. The two light weight aluminum hubs press match onto an elastomeric middle spacer named “the spider” enabling constant zero-backlash operation. Ever-electric power zero-backlash jaw couplings possess a balanced design for lowered vibration at speeds up to 8,000 RPM. Hubs are made with or without keyways in clamp or arranged screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be purchased in three durometers enabling the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are commonly used in applications with high acceleration/deceleration curves where dampening and precise action control are required.
Oldham Couplings
Ever-power created oldham couplings have an extremely customizable three-piece style, are zero-backlash, and have great parallel misalignment capabilities. Two anodized aluminum hubs press fit into the mating slots of the guts disk allowing for zero-backlash procedure and low bearing loads. Ever-electric power oldham couplings have a balanced design for decreased vibration at speeds up to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or established screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks are available in three components allowing the user to complement coupling performance with program requirements. They are commonly found in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-ability slit couplings are an alloy, one part configuration made to provide smooth tranny of motion, large torsional stiffness, low bearing loads, and long life. The slot pattern provides the best stability between zero backlash, torsional stiffness and low bearing load. With two units of identical slot machine games, the mini slit coupling is usually constant velocity by style and handles angular, parallel and axial offset. Obtainable in 6 and 8 mm diameters and allowable boosts to 70,000 rpm, slit couplings certainly are a reliable one piece coupling design that approaches the functionality of a bellows coupling.
Rotating shaft-driven mechanical elements are commonly found in all forms of machinery that perform the many processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as for example bearings, which can result in early inability of both.
o Shaft ends could be misaligned radially or angularly, exhibit axial displacement, or experience a mixture of all three.
o Drive couplings can be utilized to pay for shaft misalignment, whether the misalignment is an intentional or an unintentional the main design.

Ever-powerdrive couplings are power transmission elements used to few the shafts of varied mechanical devices, and compensate for shaft misalignment, reducing stress in shafts and bearings. Beam-style couplings are created for servo applications, providing the versatility of bellows couplings plus torsional stiffness and strength of disc couplings.

Servo couplings from Ever-power are available in a multitude of types, sizes, and products to match differing program requirements. Choosing the correct servo coupling can be a difficult process that involves many performance elements including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system functionality. Ever-power gives servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing the user to choose the coupling that best fits their request. All Ever-ability couplings are zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings can be found in many different attachment styles in addition to a vast selection of sizes and supplies to suite your specific application and/or customized requirements. Maintaining optimum program performance relies on correctly complementing a shaft coupling based on your specific performance and application requirements and criteria. At Helical, we’ve considered the guesswork out of picking the complete servo coupling for your application by factoring in essential part dynamics such as shaft misalignment, space requirements, torque, and RPM.
