67 Heavy Industrial Shock Absorbers ECA to ECA 4 Enertrols durable ECA, ECA 3 and 4" Bore Series of self-compensating shock absorbers have been designed to handle extremely heavy-duty applications and to provide controlled linear deceleration under changing conditions. cycle ratings for these proven performers range from 3,000 in-lbs (3,616 Nm) to 1,10,000 in-lbs (16,500 Nm). These dependable models also offer wide effective weight ranges for handling numerous applications. They are available self-contained or for use with an external air/oil tank. A variety of mounting options are available including: front and rear flanges, side-foot mount and clevis mount. Applications include: foundry, steel, marine, lumber and other heavy equipment industries. Technical Data Impact velocity range: 1 to 16.5 ft/ (0.30 to 5 m/) Operating temperature: 10 to 150 F (-1 to 66 C) Mechanical stop: ", 3" bore: Must be provided.09 inch (.3 mm) before end of stroke. 4" bore: Must be provided 0.09 inch (.3 mm) before end of stroke. Oil type: ATF Materials: Steel body with black oxide finish. Piston rod high tensile steel, hardened and chrome plated. spring zinc plated.
