IMPORTANT RECEIVING INSTRUCTIONS

Visually inspect all compone nts for shipping damage . If any shipping damage is found, notify carrier at once. Shipping damage is responsible fo r all repair or replacement cos t resulting from damage in shipment.

DESCRIPTIO N

These pull cylinders are designed to push/pull in a straight direction with no side loading. Single- and double-acting models are available in most c apac i ties. Plunger bolts are not supplied with cylinders. Plunger bolts must be quality Gra de 8 (8.8 DIN 912).

(1)Hi gh flow rates can lead to excessive cylinder speed which can cause cylinder damage.

Hydraulic pressure and cyli n der speed must be adjusted to match the parti cular cylinder. The push/pull force also varies wit h the system pressure. Refer to the operating specifications above.

(2)Flow controls with return checks may be required to reduce pull cyli n der speed to the

recommended rate. The return checks help minimize back pressure that could l e ad to an unclamp malfunction on single-acting systems.

(3)When using single-acting pull cylinders, limit the return flow back pre ssure to

3,45 bar (50 psi) maximum. Large diameter tubing (10 mm O.D. or larger) and f low controls with free flow return checks help minimize back pr essure. Consult Enerpac for proper system design.

MOUNTING SPECIFICATIONS

Mounting Threaded Body Cylinder s

Threaded body cylinders can be threaded into a tapped hole, s ecured to the fixture using a mounting flange, threaded into the fixture and secured with a jam nut, or mounted through a c learance hole and secured with jam nuts. See illustrations below.

Figure 1

When a threaded body pull cylinder is being installed in a fixture, the thread engagement should be no less than the thread engagement f or the standard Enerpac mounting flange. If a cylinder is being mounted using just the lower portion of the threads , the engagement should be increased f o r additional support. See table below for minimum thread engagement.

Before manifold mounting the pull c ylinder, remove the port screw plugs and copper ga ske ts or o-rings.

Prior to mounting and bolting down the pull cylinder, lubricate the o-rings provided and install them in the counter-bore around the port.

Be sure that the o-ring does not get pinched or damaged during mounting as leakage c ould result. T o prevent leakage from the manifold mounting, provide a fixture mounting surface with flatness within 0.08 mm (0.003 in.) and a surface roughness not to exc eed Ra 1, 6.

A CAUT ION

—To ensure maximum cylinder performance and safety; be sure all hydraulic

connections, hoses, and fit tin gs are properl y sealed and fully tightened.

—Be sure al l items are rated to withstan d system pr essures. Under-rated

components will not wit hstand higher pressure. Using under-rated components will lead t o equipment damage and possible personal i njury.

Vent Plug

Single-acting cylinders have a vented plug on the left side of the cylinder when you a re facing the hydraulic ports. To prevent entry of chips and coolant, the vent plug must not be removed. If the vent plug is subjec ted to a continuous coolant flood c ondition, attac h tubing to the port using a BSPP fitting and run the tubing to a non-contaminated area o f the fixture.

Pressure and Flow Settings

A CAUTION

It i s very i mportant that you use the correct pressure and flow setti ngs. Operating outside these limits will cause damage to the cylinder. Damage caused by exceeding rated pressur e and maximum flow is NOT COVERED BY WARRANTY.
