Thru-Hole Hydraulic Ram

Accessories

All size thru-hole rams are supplied with a thru-hole insert threaded into the top. Optional threaded inserts, inch or metric, are also available.

A  thru-hole  ram  easily  converts
a  manual  strap  clamp  into  an
automatic  hydraulic  powered
clamp.  Usually  a  longer  bolt  is
the  only  part  needed  to  make
this conversion.

Symbol

By inserting a rod through the hollow piston, these cylinders can be used to push or pull
depending on the orientation of the ram. They will actuate a rod of any length or shape
and are extremely effective in translating power to a remote location. Greater forces are
generated in these thru-hole rams because of their larger piston area.

Features:

 

Larger piston diameter for greater clamping forces

 

Hardened steel piston and rod

 

Single-acting for simple plumbing

 

Optional threaded inserts

 

Optional mounting plate (permits mounting ram with a single cap screw)
