Floating shaft couplings

Floating Shaft CD couplings provide a torsionally stiff, zero-backlash option for connecting long distances between shaft ends.

Features & benefits

  • Flex element made of composite material simultaneously allows high torsional stiffness and low bearing loads

  • Custom designs available: Torques from 270 to 550,000 in.-lb; speeds from 500 to 15,000 rpm; lengths from 46 to 196 in.; hub ODs from 2.25 to 12 in.

  • Spacer materials include aluminum, steel, stainless steel, and titanium; custom finishes and several hub options available

Steel bellows coupling

The backlash-free primeflex coupling can be plugged in for easy installation and disassembly.

Features & benefits

  • Can be dismantled safely without putting the steel bellows at risk, even after long operating periods

  • Mounts easily to shafts via clamping or shrink disk connections

  • Compensates for axial, radial, and angular shaft misalignments

  • Torque transmitted with frictional locking or frictional and positive locking

Slit type plastic couplings

S50TLC Inch and Metric Series couplings offer low cost, UV resistance, and voltage and RF isolation.

Features & benefits

  • Sizes 13, 19, and 25 available; made of engineered polymer with stainless steel fasteners

  • Can replace stainless or aluminum versions; lower cost, lighter weight

  • No windup, backlash, or derating for reversing applications; suitable for tight or skewed connections

  • Bore sizes from 0.125 to 0.50 in.; lengths from 0.71 to 1.40 in.

Adjustable line shafts

By using a high-strength intermediate collar between two telescoping sections of precision tubing, EZV line shafts locate phase adjustment apparatus in an accessible space.

Features & benefits

  • Adjustable for both length and phase; torque ratings to 1,200 Nm; lengths to 4 m

  • For different machines, alternate hub designs are available, such as EK7 expanding mandrels and EK6 high strength conical clamp ends

  • Can also be made with torsionally rigid bellows couplings or integral mechanical torque limiters
