These types of cylinders have end flanges welded or threaded to the barrel and the end caps are attached to each flange. End caps are secured in place by bolts that go through holes in each end cap and thread into tapped holes in each end flange.
This construction is lighter and more compact than the standard tie-rod type. In some cases cylinders having thick barrel walls, end caps will be directly bolted to the barrel Jami Hydraulics is an ISO 9001:2015 certified manufacturer of Both Sides Bolting Type Hydraulic cylinders designed specifically for reliable, trouble free operation, making it ideal for heavy duty applications & are built to withstand the buckling under compressive loads A Safety Factor of 2.5 or better is built into cylinder.
The Safety Factor is a function of the critical buckling load determined basically by the length of the cylinder and cylinder extensions Forces. Every cylinder is individually tested before leaving our plant to assure proper and leak free operation
