Removable Retainer Plate The retainer plate and rod bushing are externally removable without disassembling the cylinder on most standard models. our capscrews securely hold and lock the retainer plate in place. 2. Rod Bushing and Seals A Ucup Rod Seal with a supporting bronze bushing is standard in Milwaukee Cylinder Series MH Cylinders.. Ports BSPP/ (ISO ) cylinder ports are standard and can be located to customer requirements. ISO ports optional.. Piston Rod The piston rod is of high strength steel, hardened and plated to resist scoring and corrosion, assuring maximum life.. Piston The piston is of fine grained alloy iron, incorporating ucup seals, ensuring nonleak HiLo pressure performance. The piston is pilot fitted and threaded to the rod.. Cylinder Barrel and Seals The barrel is of steel tubing, honed to a fine finish to assure superior sealing, minimum friction and maximum seal life. 8. TieRods and Nuts The tierods are constructed from a high quality medium carbon steel. On most sizes the threads are rolled for rigid engagement of the selflocking nuts.. Cushions Cushions are machined to close tolerance to provide positive, smooth deceleration at the end of stroke. On all bore sizes, we provide the longest cushion possible based on the rod size and blind end caps. Longer cushions are available; for further information, consult factory.. Cushion Needle Adjustment and Ball Check The cushion needle adjustment valve and cushioncheck ball retainer screw are specifically designed to provide full cushion adjustment.. nd Caps nd caps and mountings are of high quality steel, precision machined for accurate mounting. 8
Performance Tested Design eatures COMBINATION ROD SAL DSIN Simple Maintenance Simple maintenance is reality with a Milwaukee Cylinder. The rod bushing or rod seals can be inspected or serviced by merely removing the cap screws and retainer plate on most models. Standard available shop tools can be used to remove the rod bushing and seals without disturbing the torque on the tierods, assuring performance quality with maintenance ease. Cushions The cushion is of a highgrade alloy, precision machined and specially tapered to provide smooth deceleration of the piston at the end of stroke. A standard manufacturing process at Milwaukee Cylinder is to assemble the piston, cushion, and the piston rod; placing the assembly between centers and checking the critical diameters for concentricity. Piston Rod Cushion Piston Rod The piston rod is hardened, plated high strength steel, machined and processed to resist scoring and corrosion, assuring maximum life. Milwaukee Cylinder offers three rod end styles as standard. The style #2 rod end with two wrench flats is furnished as standard unless otherwise specified. Special rod ends and extra wrench flats are also available. They must be specified at the time of order, giving the dimensional requirements and the location of additional wrench flats. The Series MH cylinder design is a onepiece rod bushing with a double lip ucup rod seal, a supporting bearing ring, and a double lip wiper. COMBINATION SALIN ROD The Series MH cylinder combines two bidirectional sealing ucup seals and a fine grained alloy iron piston. This proven piston seal design is effective at both high and low pressures. The design gives the wear and shock absorbing qualities of cast iron and the near zero leakage of the ucup seals.

Series MH, Tie Rod Mount Series MH Series H & mm Cylinders mm mm mm extra height applies to port face at the rod end caps only. TI ROD MOUNTD CLINDRS The flange and tierod mounts are basically the same, except that the cylinder tierods are extended and used to mount the cylinder. To prevent misalignment, sagging, or possible binding of the cylinder, when long strokes are required, the free end should be supported. The best use of tierods when extending on the blind end is in a thrust load application. hen using tierods extended on the rod end, the best application is a tension load. Tie rod mounts are suited for many applications, but it should be noted that they are not as rigid as the flange type of mounting.

SOLID ND CAP MOUNTD CLINDRS Milwaukee Cylinder's solid end cap mount is one of the strongest, most rigid methods of mounting. This type of rod end cap mounting is best in a tension application.

SID OR LU MOUNTD CLINDRS The side or lug mounted cylinder provides a fairly rigid mount. These types of cylinders can tolerate a slight amount of misalignment when the cylinder is at full stroke, but as the piston moves toward the blind end, the tolerance for misalignment decreases. It is important to note that if the cylinder is used properly (without misalignment), the mounting bolts are either in simple shear or tension without any compound stresses.

DOUBL ROD ND CLINDRS Double rod end styles are available in every mounting style except clevis. On double rod end cylinders where the rod ends are not the same, be sure to specify clearly which rod end is to go at which end of the cylinder in relation to your mounting requirements. To obtain dimensional information on a double rod end cylinder, first select the desired mounting style and refer to the corresponding single rod end cylinder model shown on the preceding pages. After you have determined all necessary dimensions from the previous page covering the desired mounting, turn back to this page. Supplement those dimensions with additional ones from the drawing below and the table at the right. These added dimensions differ from, or are in addition to, those shown on the preceding pages and provide the additional information needed to completely dimension a double rod end cylinder model. On a double rod end cylinder where two different rod ends are required, or two different rod sizes are required, or cushions on one end are required, be sure to state clearly which rod is to go at which end of the cylinder. hen two types of mounting styles are required, be sure to specify their relationship to the piston rods, if they are not the same.
