Hydraulic Actuators and Control Components - Hydraulics and Pneumatics

A double-rod cylinder, also known as through rod cylinder, has piston rods extending from both ends of the cylinder.

DOUBLE-ROD AND RODLESS CYLINDERS

1. Double-Rod Cylinder (or Through Rod Cylinder)


A double-rod cylinder, also known as through rod cylinder, has piston rods extending from both ends of the cylinder.

Fig.5.8 illustrates a double-rod cylinder. 

These cylinders produce equal force and speed on both sides of the cylinder.

2. Rodless Cylinder

As the name implies, a rodless cylinder has no piston rod, being constructed with a slide table assembly mounted directly above the piston. The table and piston are connected either directly, using a slot cut along the top of the cylinder body, or indirectly, through magnets located on both the piston and table.

Rodless cylinders are being developed to overcome the space limitations of conventional actuators. They provide relatively compact, space saving devices, capable of moving or positioning components or tools in assembly and automation systems. 

Typical applications include assembly automation, packaging, electronics, etc.
