OTC 4121 30-Ton Center Hole Power Twin Hydraulic Ram.
Use this ram with Grip-O-Matic Pullers, push-pullers, and shop presses.
OTC's center-hole rams are ideal for jobs that require a great deal of force and a relatively short stroke. Compared to the force it develops, each center-hole Power twin ram is lightweight, compact, and easy to handle, permitting its use in confined quarters. Center-hole feature permits extending jacking screws, cables, puller screws, etc., straight through the ram.
For added job versatility, Power Twin rams also feature a basic head which allows the operator to change from a tapped hole to a plain hole by merely changing the head insert (held in place by a socket-head set screw). In certain applications, the use of a plain insert is desired, since it permits using a speed nut for necessary readjustment after the ram has been extended, rather than turning the screw with a speed crank.
Single-acting hydraulic ram comes complete with OTC21873 threaded ram head insert, ram attaching screws, and OTC9796 ram half coupler.
