With the TRD Manufacturing TM series, you can tandem any series of cylinder together to provide unlimited design possibilities.

The “air over oil” design is the most common use of tandem cylinders today. Choose from different designs to gain maximum benefit for your application.

AIR OVER OIL BENEFITS

• Air typically provides the force to extend and retract the cylinder
• Oil provides the precise control of the stroke

CONSTANT VELOCITY

• By metering the flow of the oil cylinder, a constant velocity is achieved throughout the stroke - even at very slow velocities that air cylinders typically chatter

SMOOTH OPERATION IN PIVOT APPLICATIONS

• Pivot applications usually have varying loads throughout the stroke
• Typically, you are supporting a load till it reaches top center, and then the load tends to run away with the influence of gravity
• Air-oil cylinders minimize the effect of gravity, providing a smooth stroke

Three basic designs to choose from to satisfy most applications

• Dual tank design for maximum flexibility and speed
• Single tank design for slower cycle rates, reducing component cost
• Air/Oil piston with single tank provides force multiplication (2:1 ratio minimum depending on bore and rod sizes)
