Stop Tubing

Stop tube is recommended to lengthen the distance between

the bushing and piston to reduce bearing loads when the

cylinder is fully extended. This is especially true of horizon-

tally mounted and long stroke cylinders. Long stroke cylinders

achieve additional stability through the use of a stop tube.

Drawing A

When specifying cylinders with long stroke and stop tube, be

sure to call out the net stroke and the length of the stop tube.

Machine design can be continued without delay by laying in a

cylinder equivalent in length to the NET STROKE PLUS STOP

TUBE LENGTH, which is referred to as GROSS STROKE.

Drawing B

This design is supplied on all non-cushion cylinders.

Mounting Classes

Standard mountings for uid power cylinders fall into three

basic groups. The groups can be summarized as follows:

Group 1 Straight Line Force Transfer with xed mounts which

absorb force on cylinder centerline.

Group 2 Pivot Force Transfer. Pivot mountings permit a

cylinder to change its alignment in one plane.

Group 3 Straight Line Force Transfer with xed mounts which

do not absorb force on cylinder centerline.

Because a cylinder’s mounting directly aects the maximum

pressure at which the cylinder can be used, the chart

below should be helpful in selection of the proper mounting

combination for your application. Stroke length, piston rod

connection to load, extra piston rod length over standard, etc.,

should be considered for thrust loads. Alloy steel mounting bolts

are recommended for all mounting styles, and thrust keys are

recommended for Group 3.

Group 1 FIXED MOUNTS which absorb force on cylinder centerline.
