500 Hydraulic Cylinders
* The Bimba "500" is a precision built, compact, lightweight hydraulic cylinder designed specifically for hydraulic use only, at pressures up to 500 psi.
* Options include extra extensions, magnets, and fluoroelastomer seals.
* Bore sizes are 1-1/16", 1-1/2", and 2".
* The 500 hydraulic cylinders have sintered bronze piston rod guide bushing and a HEX-STUD® made from heat-treated alloy steel. Tie Bands reinforce both ends of type 304 stainless steel body rolled in a groove on the periphery of each end cap, doubling joint strength. Buna N rod wiper seal assures dry drip free piston rod. The piston rod is piloted into the piston-threaded and riveted.

Enerpac has introduced a new range of single and double acting aluminium cylinders with lifting capacities of 20 to 150 tons and stroke lengths up to 250 millimeters. This new aluminium cylinders is the most expansive one in the industry. Utilizing the latest in Alloy technology, high-strength coatings, seal design and bearing materials, the new cylinders have the strength of steel but all the advantages of aluminium. The cylinders are lightweight. Designed for a wide variety of construction and heavy load-moving applications, the line includes the single-acting RAC Series, the double-acting RAR Series, the RACL Series single acting lock-nut, and RACH Series single acting hollow plunger. Each series is made from 7075T-6 aluminium Alloy, with a complete Hard Kote treatment. Composite bearings on all moving surfaces guarantee NO metal-to-metal contact, increasing side-load resistance and increasing cylinder life. Removable hardened saddles and steel base plates, standard features of each series, protect the plungers and cylinder bases from surface contact.
