Spring-Return Hollow Center Hydraulic Ram
Ideal for push/pull applications found in off-highway, construction, mining, and other industries where heavy equipment is maintained. Center hole permits extending screws, cables, etc., straight through the ram for versatility of application. Ram withstands full “dead-end” loads. Chrome-plated piston rods resist wear, and superior packings and seals provide high cycle life without leakage. Piston head inserts are inter-changeable for versatility, and tapped base mounting holes provide easy installation in fixed applications.
