Modification Options for Parker Air Cylinders

Metallic Rod Wiper Gland Assembly

Metallic rod wipers can be supplied instead of the standard wipers if specified. These are recommended in applications where contaminants could adhere to the extended piston rod and would damage the standard wiper. Installation of a metallic rod wiper assembly does not affect cylinder dimensions.

Rod End Boots

Most Parker cylinders have a hardened bearing surface on the standard piston rod to resist external damage and are equipped with a high efficiency wiper to remove external dust and dirt. Exposed piston rods that are exposed to contaminants with air-hardening properties, such as paint, should be protected. The use of a collapsing cover, commonly referred to as a "boot," should be considered in these applications. Calculate the longer rod end required to accommodate the collapsed length of the boot from the table below.

RD 1/2 5/8 1  1-3/8 1-3/4
OD 2-1/4  2-1/4 2-5/8 3  3-3/8
LF .13  .13 .13  .13  .13
 Parker Air Cylinder Rod End Boot Dimensions

To determine extra length of the piston rod required to accomodate a boot, caluclate using the following formula:

BL = Stroke x LF + 1-1/8"

BL = std LAF (male rod end) or WF (female rod end) dimension = length of piston rod to extend beyond the head face

Note: Please compare the boot OD size to the standard E dimension per desired cylinder series and bore. This may be critical for foot mounted cylinders.

Tandem Cylinders

A tandem cylinder is made up of two cylinders mounted in line with pistons connected by a common piston rod, and rod seals installed between the cylinders to permit double-acting operation of each. Tandem cylinders allow increased output force when mounting width and height are restricted.

Duplex Cylinders

A duplex cylinder is made up of two cylinders mounted in line with pistons not connected and with rod seals installed between the cylinders to permit double-acting operation of each. Cylinders may be mounted with piston rod to piston or back to back, and are generally used to provide three position operation.
