Servo Couplings are chemical- and heat-tolerant.
SERVOMAX TX1 molded thermoplastic insert couplings are suited for pump drive and servo applications. Couplings feature elastomer element press fit between 2 precision molded coupling halves, giving it zero backlash. Sizes are available with bore diameters from .375-1.75 in., with torque capacities from 17.7-5,841 lb-in., and in various shore values to meet application needs.
Read More »Bellows Coupling uses stainless steel bellows for rigidity.
Suited for precision servo applications, compact Model BKC exhibits high torsional rigidity with zero backlash and flexibility across all 3 axes of possible shaft misalignment. Connection between stainless steel bellows and aluminum clamping hub is buried within fit-length of hub itself. Shaft hubs are custom bored on each side for shaft sizes from 5/16-2.95 in., with or without keyways. Sizes...

Insert Couplings transmit torque up to 4,000 lb-in.
Servomax Series EZ2 line shaft couplings incorporate backlash-free, vibration damping elastomer inserts. Couplings span distances from 4-13 ft without center support and transmit torques from 88.5-4,000 lb-in. Coupling ends have elastomer element pressed between 2 sets of precision machined jaws, providing zero backlash, guaranteed concentricity, and electrical insulation. Inserts are available...

Coupling suits wash-down and clean-room applications.
Series FK flexible miniature coupling measures 5.5 x 9 mm and incorporates flexible beam-cut polyamide element clamped to shafting with stainless steel hubs and set screws. Low lateral spring stiffness maintains backlash-free characteristics at torsional stiffness of 23 Ncm/rad. Hub design provides clearance for shaft burrs created by 2 mm set screws. Nominal torque capacity is 1.4 oz-in. and...

Coupling suits rapid acceleration/deceleration cycles.
Series EK7 Zero Backlash Coupling mounts to hollow bores with expanding tapered clamping element, making it suitable for belt-driven linear actuators. It reduces system size by reducing coupling adapter flange by length of 1 hub. Elastomer insert, pressed fit between precision machined jaws, dampens vibration. Coupling hub accommodates shaft dia from 3/16-2Ã-¼ in., and expanding hub...

Bellow Couplings feature zero backlash.
Series BK2 Couplings have stainless steel bellow, which exhibits high torsional rigidity and can simultaneously compensate for axial, angular, and lateral misalignment. Shaft hubs are custom-bored on each side for shaft sizes from 0.38-3.13 in. with or without keyways. Sizes are available for torque capacities from 133-13,275 lb-in.

Elastomer Couplings feature conical tappered hubs.
SERVOMAX EK6 Couplings have elastomer element that is press fit between two precision machined coupling halves, giving them zero backlash. Elastomer insert also electrically insulates two coupling halves. Hubs are mounted axially onto shaft using conical tapered segments. Three different shore values allow user to choose dampening effect. Sizes are available for torque capacities ranging from...

Miniature Bellows Coupling offers clamping hubs.
Flexible Series MK2 torsionally rigid drive component is backlash and maintenance free, and balanced for high speed. Coupling mounts with 2 clamping screws, and incorporates stainless steel bellow that compensates for axial, lateral, and angular shaft misalignments simultaneously. It is available for torque range from 4-88.5 lb-in.

Servo Insert Coupling handles up to 450 Nm.
Series ES2 has elastomer element that is press fit between coupling halves, providing zero backlash. Insert is offered in 3 shore values, allowing customer to choose damping effect. Integrated ball-detent torque-limiting element disengages drive within milliseconds in event of machine jam. It is available in versions that will free-wheel until manually reset, or that will automatically re-engage...
