Forged Hydraulic Cylinder Ends & Caps
Forged Hydraulic Cylinder Ends & Caps
Forged Hydraulic Cylinder Ends.
Forged Steel Caps and Weld-On Ends, Machined to Your Drawing.
A hydraulic cylinder end, also called a cylinder cap or base, closes the end of the cylinder tube and usually carries the rear mounting and oil port. Weld-on ends are welded directly to the tube.
Donlouco manufactures forged steel cylinder ends and caps for cylinder manufacturers across Europe. They are forged by approved partners to Donlouco tooling, then CNC machined and inspected in our own facility in Jiashan, China.
Specs.

Oil ports machined to SAE, T2A, JIC and other standards
High volumes, to exact customer specification
Custom Finishing, Threading and Boring.
Each cylinder end is machined after forging: the weld prep or spigot that locates on the tube, internal threads and oil ports, and the mounting bore or eye. Accurate weld preps give a consistent, full-penetration weld to the tube. Machined sealing faces and ports keep the hydraulic fluid where it belongs.
Forged or Machined from Solid?
Forged cylinder ends have a continuous grain flow that follows the shape of the part. That makes them stronger and more fatigue-resistant than an equivalent end machined from solid bar, and it uses less material at volume. For lower volumes or simpler shapes, see our cylinder end caps machined from solid. For the rod end of the cylinder, see rod eyes and rod ends with spherical bearings.
Consolidated Shipments.
From our own facility in Jiashan, we consolidate parts for multiple products and customers into regular container shipments to Europe. You get the flexibility to order what you need, with door-to-door delivery and customs handled by Donlouco.

A hydraulic cylinder end, or cap, closes the end of the cylinder tube and typically carries the rear mounting and oil port. Donlouco manufactures forged steel cylinder ends machined to customer drawings.
-
Weld-on ends are cylinder caps welded directly to the cylinder tube, rather than threaded or bolted on. They need an accurately machined weld prep for a strong, consistent weld.
-
Forging aligns the steel’s grain with the part’s shape, giving greater strength and fatigue resistance than casting or machining from solid. That matters for a part that holds full cylinder pressure.
