Forged Hydraulic Components
Hydraulic systems run at pressures where a porous component simply weeps. Forged rods, caps and manifold bodies deliver the density that keeps a 250-bar circuit dry over thousands of cycles.
- Rod Diameter
- 20 mm – 200 mm
- Rod Length
- Up to 2,000 mm
- Materials
- EN8, EN19, CK45, 42CrMo4
- Surface Hardness
- Induction hardened, ground
- Components
- Rods, caps, glands, manifolds
- Applications
- Excavators, presses, tippers, machinery

Pressure Density in Manifold Bodies
A manifold block is drilled with intersecting galleries; any porosity between two of them becomes an internal cross-leak that is almost impossible to diagnose in the field. Forged stock eliminates that failure mode entirely.
- No inter-gallery porosity
- Uniform properties through section
- Clean drilling and tapping
- Pressure tested where specified
Cylinder Rods and Surface Duty
Rods are forged, induction hardened, ground and, where required, hard chrome plated. Straightness and surface finish are what determine seal life, so both are verified before plating rather than after.
End Caps and Gland Nuts
Thread strength and seal groove accuracy govern whether a cylinder holds pressure. Threads are gauge verified and grooves machined to the seal manufacturer's dimensional and finish specification.
Hydraulic Component Capability
Hydraulic systems run at pressures where a porous component simply weeps, and a manifold block drilled with intersecting galleries is the worst case: porosity between two galleries becomes an internal cross-leak that is almost impossible to diagnose in the field. Forged stock removes that failure mode entirely.

Rod Surfaces and Seal Life
A cylinder rod's surface is what the seal runs against for the machine's life, so straightness, hardness and surface finish decide seal life more than the seal specification does. Rods are forged, induction hardened, ground and, where specified, hard chrome plated through qualified processors. Seal grooves in end caps and gland nuts are machined to the seal manufacturer's dimensional and finish data rather than to a nominal dimension, and threads are gauge verified because thread strength is what holds the cylinder together under pressure.
- Ground rod surfaces with straightness verified
- Seal grooves machined to the seal maker's data
- Manifold blocks pressure tested where specified
- Threads gauge verified before dispatch

Questions Answered
Do you chrome plate cylinder rods?
+
Grinding is done in-house; hard chrome plating is completed through qualified partner processors with certificates supplied.
Are manifold blocks pressure tested?
+
Yes, where the customer specifies, with test pressure and duration recorded on the report.
What rod sizes do you cover?
+
20 mm to 200 mm diameter and up to 2,000 mm length.
Can you machine seal grooves to a seal maker's spec?
+
Yes, groove dimensions and surface finish are machined to the seal manufacturer's data sheet.
