Solutions
What Do You Need Your Machine to Do?
Packaging. Quick stop-start, accurate indexing and jam protection on fillers, cartoners, wrappers and case packers.
Food & beverage. Sealed, wash-down torque limiters and clutches, and brakes that hold lifts and transfers if the air fails.
Printing & converting. Steady tension on unwinds and rewinds, web guiding, and fast clutches for presses, slitters and laminators.
Materials handling. Clutch-brakes for conveyors, jam protection on gearboxes, and brakes that hold loads on hoists, lifts and transfer cars.
Machine tool. Rack and pinion with no play for long axes, and brakes that hold position safely.
Robotics & automation. Precise positioning on gantries and robot tracks, with safety brakes on vertical and servo axes.
Textile & wire. Steady tension and smooth-starting clutches for winding, twisting and drawing.
Automotive. Press lines, body-shop transfers and assembly automation – positioning, holding and jam protection.
Mining & mineral processing. Jam protection and clutch-brakes for conveyors and crushers, and rod locks that hold loads if the air fails.
Metal fabrication & cutting. Fast, accurate gantries for plasma, laser and waterjet cutting and welding, with brakes that hold the axes.
Timber & woodworking. Long, accurate axes for CNC routers and saws, and jam protection on conveyors and feeders.
Plastics & moulding. Rod locks and brakes that hold moulds, platens and presses in place when the power is off.
Lifts, stages & rides. Safety brakes and rod locks that hold lifts, scissor tables, stage platforms and ride equipment if air or power fails.
Medical & pharmaceutical. Precise positioning and no-play holding brakes for medical, imaging and pharmaceutical machines.
Start, Stop & Cycle
Start and stop the drive on cue – smooth starts, quick cycling and controlled stops, all day long.
Protect Against Jams & Overload
Cut the drive the moment something jams, before the gearbox, the machine or the product is damaged.
Stop & Hold a Load Safely
NexSafe brakes clamp on with springs if air or power is lost – on cylinder rods, guide rails and servo motors.
Position Precisely
Move to an exact position with no play – in a straight line over any distance, or round a rotary table.
Control Web Tension
Keep paper, film, foil and wire at a steady tension and running straight, from a full roll to an empty core.
Keep It Running
Rebuild worn Air Champ clutches and brakes with a kit – find it from the model on the nameplate.
