Where drives are put to the test
Shock loads, shaft misalignment, continuous duty, harsh environments: REEL couplings and drive elements work wherever torque has to be transmitted reliably under real conditions.

From load profile to design
Whether shock load, misalignment, continuous running or a corrosive environment: REEL engineers the right design for the actual load case, on a manufacturer-neutral basis and with 1:1 replacement for existing plant.
-
Crushers, mills and shredders generate high torque shocks that the drive has to withstand.
Flexible couplings turn shocks into heat through the material damping of their buffer elements and so protect the coupled machine parts. REEL builds pin and cam couplings such as ELBO-R, ELBO-B and REELFLEX with replaceable buffers that are changed as a complete set when worn. For higher demands we match size and buffer hardness to the shock profile, on a manufacturer-neutral basis and with 1:1 replacement for installed plant.

- Material damping, buffers replaceable as a set
-
Assembly tolerances and thermal expansion shift shafts axially, radially and angularly.
Flexible couplings compensate this misalignment through compliant elements while damping vibration; they are the design that takes up shaft displacement. Stiff clamp couplings similar to DIN 115 and flange couplings to DIN 116, by contrast, transmit torque stiffly and without backlash, but require aligned shafts. Torsionally stiff disc couplings compensate shaft misalignment and, thanks to their high power density, transmit considerably more power than flexible couplings. Especially in rolling and steel mills, REEL sizes the coupling to the actual misalignment, on a manufacturer-neutral basis and with 1:1 replacement for existing components.

Pumps, fans, compressors and conveyors often run around the clock; availability is productivity.
For high availability we rely on low-maintenance couplings that run smoothly; ELBO-R, ELBO-B, REELFLEX and ZARIFLEX damp vibration and protect bearings and units. On many designs the wear parts can be changed without dismantling, so maintenance fits into planned windows. Spare parts come straight from the manufacturer in Troisdorf, including for older installations and 1:1 for other makes.

Corrosive media, seawater, dust and high speeds place special demands on the drive.
For chemicals, water, ports and energy we supply couplings in stainless steel and special materials with corrosion protection, and at high speeds we design for smooth, low-vibration running. As a manufacturer with in-house design, we match material and design to the environment instead of accepting a catalogue compromise. Through the trade programme we recommend on a manufacturer-neutral basis and also supply 1:1 replacements for existing plant.

Frequently asked questions
Which coupling suits shock loads?
Flexible couplings with replaceable buffer elements such as ELBO-R, ELBO-B or REELFLEX damp shocks through material damping and protect the machine. We match size and buffer hardness to the shock profile.
Does a stiff coupling compensate misalignment?
No. Stiff clamp couplings similar to DIN 115 and flange couplings to DIN 116 require aligned shafts. Misalignment is compensated by flexible couplings through compliant elements, and also by the torsionally stiff disc coupling; the choice depends on the expected misalignment and the stiffness required.
Which coupling fits continuous duty?
Low-maintenance, vibration-damping couplings whose wear parts can often be changed without dismantling. Spare-parts supply comes straight from the manufacturer, including for older plant.
Are there couplings for corrosive environments?
Yes. For chemicals, water or ports we supply designs in stainless steel and special materials with corrosion protection, matched to the environment and the speed.
