Plan your fixture installation with operator safety in mind. y nature, most clamping devices have pinch points. Many times the fixture can be designed to shield the operator from a pinching hazard. Often the placement of the clamping device in the fixture can minimize the gap between the clamp and the workpiece, thus reducing or eliminating the pinch point. Perhaps the clamping control valve or switch can be located such that the operator cannot reach the fixture and the control at the same time. ual palm buttons on electricallyactuated systems serve the same purpose. o not require the operator to hold the workpiece in position during the clamping operation. Make sure that the workpiece is self-supporting and self-locating so that operator hands are out of danger when the hydraulic system is actuated. Often a simple spring plunger is all that is necessary. The lowest pressure rating of any component in the clamping system sets the maximum pressure rating for the entire system. Most hydraulic workholding components are rated at 5, PSI maximum. owever, some components are rated at less than 5, PSI. The maximum pressure is listed on each product page of this catalog. Never exceed this rating. Just having a clamp that is rated at 5, PSI is not enough. very hose, fitting, valve, adapter and tube exposed to pressure must be rated at or above the maximum hydraulic system pressure. Most uilding safe hydraulic systems hardware store fittings are intended only for low pressure plumbing. Never use water pipe fittings or copper tubing and brass fittings for hydraulic service. Use proper tools when bending tubing, and maintain proper minimum bend radii for hoses and tubing. If a hose or tube is ever kinked, replace it. on t risk a rupture. Fluid escaping under high pressure is dangerous. The resulting loss in pressure could release the workpiece from the fixture and cause serious injury and equipment damage by being ejected from the machine or breaking tooling. Tubing and hoses do flex when pressurized. llow for that movement by supporting the fluid lines away from surfaces which could abrade the surface and eventually cause damage. void straight lengths of hose and tubing. bend will allow for this deflection without putting too much stress on the line. ven if proper hydraulic tubing and fittings are specified, be sure to protect them from abuse. omponents damaged from abrasion or accidental dropping of a workpiece will no longer have the strength and safety of the original design. Use proper mounting hardware when installing workholding clamps and other components. lways use the largest bolt available to fit in the mounting hole. In many cases, the recommended cap screw or thread is specified on the product page of this catalog. Sometimes the mounting hardware is included with the component. lways use supplied hardware.

They offer tremendous force in a small, easily mounted package that can be used in any attitude and requires only a single inlet port. They are often used grouped together by a common manifold to provide as much force as needed for the operation. For a relatively small volume of oil, they provide exceptional exerting force, and are generally the best choice if stroke lengths can be kept short. Features: Threaded body for easy mounting Small size permits low profile workholding ccessories available for easy mounting vailable in metric or inch sizes (Metric on special request) ardened piston and rod Single-acting for simple plumbing Wide variety of sizes and strokes Pressure capacity up to 5, PSIG, provided piston does not bottom out Technical Information Model no.

The two models available provide oil displacements ranging from 1 cu. in. to 4 cu. in. per stroke. With the system filled, the volume of oil required to actuate a cylinder or pressure point is only equal to the cubic content of the piston displacement. The small booster, producing 1 cu. in. of usable oil per stroke, can operate 5 of the tiny 1/2-2 pressure points a full.22 max. stroke, and even more when strokes are kept to a minimum. Features: uilt-in manifold omplete automatic bleeding with each return stroke utomatic relief of system overcharge utomatic bleeding feature eliminates pre-filling Large volume visible oil reservoir automatically replenishes the system with reserve oil capacity orrosion and wear-resistant materials Wear rings on hydraulic piston tube Unique self-centering air piston assures long life Increases hydraulic pressure to 3, PSIG from 1 PSIG air-line pressure ll models supplied with S hydraulic ports NPT hydraulic ports available on request Model no.
