HIGH PRESSURE HYDRAULIC CYLINDERS IMPROVED CUSHION ADJUSTMENT - Newly designed needle valve is interchangeable with currenl design and offers improved sealing characteristics. HEAVY WALL steel tubing, precision honed with extra long stones to provide over-lap and eliminate a spiral condition detrimental to long stroke cylinders. The resulting ultra-smooth finish provides maximum seal life. ROD WIPER - Wipes rod clean and dry. Keeps foreign matter from entering cylinder, extending packing life CUSHION ADJUSTMENT NEEDLE - Needle valves and ball check drilling and machining are identical,...

Bore Size Selection Unlike air applications, the output force of a cylinder for hydraulic service need be only slightly greater than the re- quired force. Hydraulic cylinder speed is dependent di- rectly on the relationship of supply flow rate to cylinder Force tables to aid In cylinder sizing are on page 35. Select the cylinder mounting which will keep the line of force as close as possible to the centerline of the piston rod and free of misalignment. This will maximize seal and bearing life. CUSTOM MODIFICATIONS Stop Tubes In long cylinders used on push applications, internal stop tubes...

FLANGE MOUNT PRESSURE LIMITATIONS (PUSH) Use Model CC (Below) or Modal J (Pago 10) for Rocom- mended Maximum Pressure. ASee Table A on page 29 for bore and rod combinations using head plates with threaded bronze gland.

These dimensions are constant regardless Double rod end models are designated by letter "X" preceding the model identification. See page 28. fDimensions refer to bolt diameter.

SQUARE-HEAD MOUNT (BLIND END FLANGE MOUNT) (ROD HEAD SQUARE MOUNT) (BLIND HEAD SQUARE MOUNT)

These dimensions are constant regardless Double rod end models are designated by letter "X" preceding the model identification. See page 30. fDimensions refer to bolt diameter.

RECTANGULAR MOUNT • BLIND HEAD RECTANGULAR MOUNT These dimensions are constant regardless Double rod end models are designated by letter "X" preceding the model identification. See page 30. tDimensions refer to bolt diameter. ASee Table A on page 29 for bore and rod combinations using head plates with threaded bronze gland.

The dimensions given on this table are affected by the piston rod diameter and the stroke. • Heads bored for these rod sizes are normally in stock- thus faster delivery. ■ Model J only. * For piston rod dimensions see page 32.

For double rod end cylinders Model A and B — subtract dimension SV from SU and add the difference to These dimensions are constant regardless Double rod end models are designated by letter "X" preceding the model identification. See page 28. tDimensions refer to bolt diameter. ASee Table A on page 29 for bore and rod combinations using head plates with threaded bronze gland.

The dimensions given on this table are affected by the piston rod diameter and the stroke. For double rod end cylinders Model S — In place of dimension SN + stroke, multiply dimension XT times 2 and to this total add the cylinder stroke. From this figure, subtract the ZM + double stroke (See Page • Heads bored for these rod sizes are normally in stock- thus faster delivery. NOTE: MODEL B EXCLUDED. * For piston rod dimensions see page 32.

Integral trunnion pins are designed for shear, nol bending, loads. Integral trunnion pins are designed for shear, not bending, loads. These dimensions are constant regardless Double rod end models are designated by letter "X" preceding the model identification. See page 28. ASee Table A on page 29 for bore and rod combinations using head plates with threaded bronze gland.

Integral trunnion pins are designed for shear, not bending loads. The intermediate trunnion pin mounting location, being non-adjustable, is determined by the "XI" dimension which should be specified by the customer. It can be located at any point between the heads of the cylinder. The dimensions given on this table are affected by the piston rod diameter and the stroke. • Heads bored for these rod sizes are normally in stock- thus faster delivery, * For piston rod dimensions see page 32.
