Hydraulic Cylinder Components: Product Overview
Hydraulic cylinder components machining produces the pressure-containing, sealing, guiding and mounting parts that convert hydraulic pressure into controlled linear force.
Each component has a different governing feature: barrel bore geometry and honing, piston seal grooves, rod diameter and surface finish, gland seal cavities, matched end-cap hole patterns, tie-rod length and mounting interfaces.

Why CNCPioneer for Hydraulic Cylinder Components?
Coordinate geometry, material, finishing and inspection around the part's intended function.
Barrel Boring and Honing to Ra 0.2
CNCPioneer provides cylinder barrel boring to ±0.005–0.010mm and precision honing to Ra 0.2–0.4μm with a 45–60° cross-hatch honing pattern that retains lubricating oil on the bore surface between piston strokes.
Matched Cylinder Kit Verification Before Shipment
Agree critical-feature checks, measuring methods and inspection records with your drawing.
Rod Coating Allowance
Specify the rod material, coating system and final diameter condition. Agree grinding, masking and thickness allowances with the finishing provider before machining the rod blank.
Single-Setup End Cap and Seal Gland Machining
Plan support and setup around critical diameters, datums and mating interfaces.
Matched Kits and Production Documentation
Complete cylinder programs can include CMM reports for barrel-to-piston and rod-to-gland relationships, matched front and rear cap verification, material certificates, coating records, PPAP or FAIR documentation and lot traceability from prototype through production.
Hydraulic Cylinder Components We Manufacture
Explore representative configurations and share your drawing for a product-specific review.
Cylinder Barrel
The primary pressure-containing body — precision-bored tube within which the piston reciprocates.
Piston
The sliding pressure boundary element dividing the barrel into cap end and rod end chambers.
Piston Rod
The output element transmitting linear force and displacement to the driven load.
Seal Gland
The precision-machined ring housing the rod seals, rod wiper, and rod bearing at the rod exit point.
Front & Rear End Caps
The structural closures sealing both ends of the cylinder barrel — rear end cap (cap end) enclosing the cap end chamber; front end cap (rod end) providing structural closure through which the piston rod passes.
Tie Rods & Mounting Hardware
Tie rods are the tension members clamping end caps against the cylinder barrel — four rods standard, extending from rear end cap through barrel flanges to front end cap, where tie rod nuts torque the rods into tension.
Industries & Applications
Hydraulic cylinder components for automated production, energy equipment, aerospace systems and automotive manufacturing. Match the material, sealing surfaces and inspection scope to the application.

Materials for Hydraulic Cylinder Components
Confirm the exact grade, delivery condition and finish compatibility with your drawing.
Barrel Standard
E355 / ASTM A519 DOM Tube
Cold-drawn seamless steel tube — the standard cylinder barrel material for most hydraulic cylinders.
Rod Standard
Ck45 (1045) + Hard Chrome
Standard hydraulic cylinder rod steel — 600 MPa yield; bright-turned and ground from precision ground bar stock; hard chrome plated 0.020–0.040mm then superfinished to Ra 0.05–0.1μm.
Piston Default
Steel 4140 Alloy Steel
The default hydraulic piston material — providing the combination of strength, machinability, and case-hardenability that most industrial and mobile hydraulic piston applications require.
Corrosion Service
Steel 17-4PH H900 Stainless
Yield strength: 1,310 MPa (H900 precipitation hardened condition); HRC 44–47 — provides adequate OD wear resistance for steel barrel bore running without chrome plating.
End Cap Standard
Ductile Iron EN-GJS-500
Standard end cap material for most industrial hydraulic cylinders — adequate yield (500 MPa) for pressure containment; excellent machinability for complex port and mounting geometries.
Lightweight Option
Aluminum 6061-T6 & 7075-T6
Aluminum options for lightweight machined components. Confirm the alloy, temper, finishing allowance and critical assembly dimensions.
