C20 Series Cast Iron Cylinders
Extremely compact for limited-space applications, the C20 Series is Sheffer’s economical cast iron pneumatic cylinder — 1-1/2″ thru 10″ cataloged bores at 200 psi standard, lubed for life with hard chrome plated piston rods standard.
Built for Compact, Economical Performance
The C20 Series Cast Iron cylinder is Sheffer’s cataloged answer for applications where space is tight and the budget has to hold. Cataloged bores run 1-1/2″ thru 10″, with specials available outside the standard range, and every unit ships lubed for life at an economical price point.
Ordering Note: The C20 Series is built to be compact without giving up durability — cast iron construction and hard chrome plated rods stand up to demanding duty in a small envelope. Confirm bore, stroke, mounting style, and cushioning with the factory before finalizing your order.
Construction That Keeps Costs Down
Every C20 Series cylinder is built around the same principle that defines the line: fit into tighter spaces, cost less to own, and require less field service. Lubed-for-life sealing and hard chrome plated rods are standard — not upgrades.
Extremely Compact Footprint
Sized for limited-space applications, the C20 Series delivers full cylinder performance in a notably smaller envelope than comparable duty cylinders.
Cast Iron Construction
A rugged cast iron body gives the C20 Series the durability to handle demanding duty cycles across its full 1-1/2″ thru 10″ bore range.
Lubed for Life
Factory-lubricated and sealed for the life of the cylinder — no relubrication schedule to manage in the field.
Economically Priced
Purpose-built to hit a competitive price point for cost-conscious applications, without sacrificing cast iron durability.
Hard Chrome Plated Piston Rods
Hard chrome plating is standard on every piston rod, improving wear resistance and corrosion protection over the life of the cylinder.
Flexible Cushioning
Cushioned front, rear, or both ends are available to soften end-of-stroke impact and extend service life in cyclic applications.
Choosing Your Cushioning
Every C20 Series cylinder runs the same compact cast iron body, hard chrome plated rod, and lubed-for-life seals. Cushioning is where you tune the cylinder to your duty cycle — soften the rod-end stroke, the cap-end stroke, or both.
Front (Rod End) Cushioned
Softens the piston’s approach at the extend stroke — the end most commonly loaded with the moving mass and linkage of the application.
Extend Stroke Reduces ImpactRear (Cap End) Cushioned
Softens the piston’s approach at the retract stroke — useful where the return travel carries most of the momentum in the cycle.
Retract Stroke Reduces ImpactBoth Ends Cushioned
Softens both extend and retract strokes — specified for high-cycle applications or wherever full-stroke travel is run at speed.
