Explosionproof Couplings are ATEX 95 and ATEX 137 certified.
Electronic Components & Devices

Explosionproof Couplings are ATEX 95 and ATEX 137 certified.

Explosionproof couplings are machined with thermally and chemically stable, wear resistant, polyurethane insert for zero backlash. Smooth fit between insert and hubs helps insert compensate for lateral, angular, and axial shaft misalignment. Impregnated with graphite, insert is electrically conductive and eliminates potential for charges arcing from one hub to other. Couplings are available in 9...

Servo Couplings are chemical- and heat-tolerant.
Electronic Components & Devices

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.

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...

Electronic Components & Devices

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 3/16-2Â-¼ in., and expanding hub...
