Nexen clutches
Connect and Disconnect the Drive, Right on Cue

How it works
How Clutches Work
A clutch connects a running motor to the machine when you want it to move, and lets go when you don’t. Air pressure presses the clutch faces together; let the air out and springs pull them apart.
Disconnect
The simplest job: connect and disconnect part of a machine now and then, from a switch or the machine control – for example, so one section of a printing press can stop while the motor keeps running.
Reverse or Change Speed
Two clutches on one shaft can run a machine forwards and backwards, or at two speeds, by engaging one or the other – quicker and easier on the motor than reversing it.
Start Gently
Letting the clutch engage gradually brings a conveyor of bottles up to speed without tipping them over. A flow control on the air sets how gently it engages.
Wind at Steady Tension
On a rewind, a clutch slips all the time to wind paper or film at a steady tension. The controller changes the air pressure as the roll grows.
How Much Torque?
Start with the torque the drive must carry. Power and speed set it, and a service factor allows for the shock of starting. This uses the catalogue formula.
Torque from power and speed
Torque = 9,550 × kW ÷ rpm × service factor (the Air Champ catalogue’s 63,000 × HP × K ÷ rpm, in metric). A guide only – we’ll check heat and cycling with you.
Why Nexen clutches
Air-Operated, and Easy to Fine-Tune
Adjusts Itself
Friction clutches take up their own wear, so they keep the same grip between services.
Smooth or Solid
Friction clutches slip a little to give a soft start. Tooth clutches lock solid and carry high torque in a small size.
Exact Position
Positioning tooth clutches lock in at set points (1 to 8 per turn), so the machine stays in time.
Made for the Conditions
Pulley, pilot or coupling mount. Tooth clutches come open, sealed (IP55) or nickel plated.
