DIMENSIONS — MODEL F and CLASS M____10-11 CLASS 1 CAST HEAD CYLINDERS For normal applications where low-cost, rugged air cylinders are required. Our exclusive design has been 'user-proven' with over 40 years of experience as the work horse of industry. CLASS 2 CAST HEAD CYLINDERS For higher operating air pressures and hydraulic use. These cylinders incorporate recessed gasketed tube seals and piston to rod O-ring seals as standard features. CLASS M CAST HEAD MILL TYPE CYLINDERS These cylinders have all the features of MOPAK Class 2 cylinders plus oversize rods and steel tubing with welded...

NOPAK CLASS 1-2-M OPTIONS AND MODIFICATIONS lore Size fhe bore size of an air cylinder should be selected to sup- ply from 125% to 200% of the required force. The excess of force versus load will result in a faster cylinder speed assuming there is an adequate supply of air into and out The bore size of a hydraulic cylinder should be selected to supply sufficient force to exceed the load by approxi- mately 20%. The cylinder speed is the result of flow into and out of the cylinder. Force tables to aid in cylinder siz- Select the cylinder mounting which will keep the line of force as close as...

Once the cylinder is assembled, its operation is entirely automatic. As the cushion sleeve enters the bore in the cylinder head, the air or fluid is trapped between the piston...

1 Adjustable Cushion provides variable cushioning capacity, preventing noisy, damaging metal-to- metal impact of piston against cylinder heads. 2 Quick-opening ball check-valve assures quick starting under full power. Permits line pressure to act on full piston area instantaneously. 3 Special Molded Composition Wide Lip self-sealing cup packings furnished as standard, Hi-Temp Seals are available at extra cost. 4 Positive Seal V-ring Stack-Packing.

CLEVIS MOUNTING* Model E is designed expressly for use in hoist service or where articulated or oscillating movement is required. It is often attached to ceiling, beam or other overhead surface, with rod end down, but is also used in the opposite position for upward pushing or tilting operations. * Mounting Bracket and Rod Clevis as shown are additional.

RIGHT ANGLE FLAT BASE Model D is similar in construction to Model C, except that the piston rod is extended through the mounting base. It may be mounted on any flat surface in which an opening can be provided for the protruding cushion boss, and ex- tension of the rod. It is used extensively in applications of inward pulling power.

TRUNNION MOUNTING The Model F Trunnion Mounting provides smooth, de- pendable cylinder power where oscillating movement is necessary in connection with heavy side thrust. Trunnion location is indicated by dimension "I," which is minimum and furnished as shown unless otherwise specified; may be increased within limits of cylinder tubing length. Model F available without trunnion — designated as Model H. End view illustrates 8 tie rod spacing bare sizes.

NOPAK Class M cylinders are strong and rugged in construction, especially designed for heavy duty appli- cations in mines, quarries, steel mills, and in the heavy construction industries. Maximum system pressure is of 5" and larger. The Class M construction is available in a full range of sizes and models (mountings) up through 14" in diameter for air, water or oil hydraulic NO TIE RODS - Cylinder flanges are welded to steel cylinder tubing.
