Beam Couplings
Ever-power made beam couplings have large angular misalignment capacities, are zero-backlash and have a balanced design for reduced vibration by boosts to 6,000 RPM. They are manufactured from a single little bit of aluminum or stainless with multiple sets of spiral cuts to provide bigger stiffness and better all-around misalignment capacities than traditional sole 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 generally found in encoder, tachometer, and mild duty power transmitting applications where precise movement control is desired.
Bellows Couplings
Ever-power made bellows couplings have large torque and torsional stiffness capacities, are zero-backlash, possess a balanced design, and will accommodate all forms of misalignment. They are made up of two anodized metal hubs and a stainless steel bellows making a light and portable low inertia coupling capable of boosts to 10,000 RPM. The thin wall structure of the stainless steel bellows can simply flex while leftover rigid under torsional loads. Ever-electricity manufactures bellows couplings hubs with or without keyways in clamp or placed screw styles with “, metric, and in . to metric bores which range from 1/8″ to at least one 1” and 3mm to 25mm. They are commonly used in powerful stepper servo devices where precise movement control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-piece assembly with a balanced design comprised of two hubs joined to one or two centre inserts called frogs. This design and style creates a compact low inertia versatile coupling capable of boosts to 25,000 RPM. Clamp design hubs are manufactured with inch, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for high customizability. The unique style of the frog concentrates forces onto its adaptable limbs enabling low bearing loads safeguarding sensitive small bearings in applications such as encoders or tachometers. Controlflex couplings will be also electrically isolating since the hubs do not touch and frogs are manufactured from acetal. They will be created by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power created disc couplings have great torque and torsional stiffness features, are zero-backlash, possess a balanced design, and may accommodate all forms of misalignment. They happen to be manufactured in single disc types for small installations and dual disc styles for bigger misalignment capabilities. Ever-electrical power disc couplings are comprised of two anodized light weight aluminum hubs, stainless steel disc springs, and a centre spacer (double disc only) creating a light in weight low inertia coupling with the capacity of speeds up to 10,000 RPM. Hubs are made with or without keyways in clamp and set screw designs with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo systems where precise motion control is required.
Jaw Couplings
Ever-power made zero-backlash jaw couplings possess a highly customizable three-piece style, have high dampening capacities, and will accommodate all kinds of misalignment. The two aluminium hubs press match onto an elastomeric middle spacer known as “the spider” enabling consistent zero-backlash operation. Ever-power zero-backlash jaw couplings have a balanced design and style for reduced vibration at speeds up to 8,000 RPM. Hubs are produced 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 32mm. Spiders can be found in three durometers enabling the user to match coupling performance with system requirements. Zero-backlash jaw couplings are generally used in applications with substantial acceleration/deceleration curves where dampening and specific movement control are required.
Oldham Couplings
Ever-power produced oldham couplings have an extremely customizable three-piece style, are zero-backlash, and have excessive parallel misalignment capabilities. Two anodized aluminum hubs press match the mating slot machine games of the guts disk enabling zero-backlash procedure and low bearing loads. Ever-electric power oldham couplings possess a balanced design for lowered vibration at speeds up to 4,500 RPM. Hubs are made 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 can be found in three products allowing the user to complement coupling performance with program requirements. They are generally found in stepper servo systems that require a high parallel misalignment coupling.
Slit Couplings
Ever-electricity slit couplings happen to be an alloy, one part configuration designed to provide smooth tranny of motion, substantial 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 models of identical slots, the mini slit coupling is usually 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 certainly are a reliable one part coupling design that methods the overall performance of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly found in all varieties of machinery that execute the various processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related elements of the assembly such as for example bearings, which can lead to early inability of both.
o Shaft ends can be misaligned radially or angularly, exhibit axial displacement, or experience a combination of all three.
o Travel couplings can be utilized to pay for shaft misalignment, if the misalignment is an intentional or perhaps an unintentional the main design.

Ever-powerdrive couplings happen to be power transmission parts used to couple the shafts of varied mechanical devices, and compensate for shaft misalignment, reducing stress on shafts and bearings. Beam-style couplings are suitable for servo applications, supplying the flexibility of bellows couplings plus torsional stiffness and strength of disc couplings.

Servo couplings from Ever-power are available in a wide variety of styles, sizes, and supplies to match differing app requirements. Choosing the right servo coupling can be a difficult process that involves many performance elements which includes: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system effectiveness. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types permitting the user to choose the coupling that greatest fits their request. All Ever-vitality couplings happen to be zero-backlash and manufactured inside our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles in addition to a vast selection of sizes and components to suite your unique application and/or custom requirements. Maintaining optimum program performance relies on effectively complementing a shaft coupling predicated on your specific performance and app requirements and specifications. At Helical, we have considered the guesswork out of picking the precise servo coupling for the application by factoring in vital component dynamics such as shaft misalignment, space requirements, torque, and RPM.
