HYC-N · ISO 6020-1 · Ø25–200 · 160 bar (max 210)
Mobile
Mobile hydraulic cylinders for construction, agricultural and material-handling OEMs.
[03]Cylinders
Custom cylinders. Engineered, tested, delivered.
Project-based hydraulic cylinder production to ISO 6020-1, ISO 6020-2 (CETOP), ISO 6022 and welded heavy-duty — manufactured by ERS Hidrolik Silindir Sanayi A.Ş., the Soydan Group cylinder plant in İzmir. Design, machining, welding, painting, assembly and marking all happen in-house at the İzmir AOSB factory — the architecture behind blank-sheet-to-shipped-unit in under 10 weeks.
[04]Engineering envelope
Standard range to project ceiling.
The standard catalogue covers the majority of OEM and industrial requirements. Larger bore, longer stroke or higher pressure opens the project range through engineering review.

[05]Hydrocyl™ range
Six families. One engineering discipline.
Hydrocyl™ is a registered trademark of Soydan Hidrolik · WIPO WO500000001719832. Every Hydrocyl cylinder carries the brand's engineering file, serialised test report and the full Soydan quality stack behind it.
Six families built to the international standards most commonly specified by European industrial OEMs — with ATEX / IECEx and SIL2 servo variants on request. Online configurator launching Q3 2026 — until then, the Drawing Studio and Instant Quote tools cover the gap.
HYC-T · ISO 6020-2 · Ø25–320 · 160 bar (max 250)
CETOP tie-rod
Industrial tie-rod cylinders to CETOP standard — press-room and machine-tool primary range.
HYC-F · ISO 6022 · Ø50–400 · 250 bar (max 350) · Flagship
Round-flange
Heavy-duty round-flange cylinders. Mill duty, steel-plant and large-bore project work.
HYC-W · To spec · Ø40–400 (Ø1,000 project) · to 400 bar
Welded heavy-duty
Fully-welded cylinders for shock, vibration and severe environments — metallurgy, marine, press forging.
HYC-M · OEM drawing · Ø40–250 · 250–350 bar
Mill-type / custom
Custom envelopes for construction machinery, excavators and loaders — built from the customer's own drawing.
HYC-S · ISO 6020-2 based · Ø40–200 · 160–250 bar
Servo / position-controlled
Integrated position feedback for test benches, process control and R&D. SIL2-capable variants.

[07]How we build
From enquiry to ex-works.
01
Drawing review
2D / 3D drawings reviewed by in-house engineering. Application data sheet to specification within 48 hours.
02
Engineering
Tube, rod, sealing, mounting and cushioning specified to ISO 6020-1 / 6020-2 / 6022 — or custom envelope.
03
Manufacturing
European raw materials, in-house welding to EN ISO 3834-2, CNC machining, surface finish, assembly.
04
Test & delivery
100% pressure tested to ISO 10100. NDT Level II inspection on welded joints. Ex-works in under 10 weeks.
[08]Materials & proof
Built from European steel. Proven twice.
What goes into a Hydrocyl™ cylinder — and what comes out with it. Every claim below ships as paper: a signed, serialised test report and the full engineering file accompany each unit.
M1
European tube & rod
Cold-drawn honed tubes from European mills (ISO H8, Ra ≤ 0.4 µm). Hard-chrome-plated rod bars from European chromed-bar specialists (ISO f7, Ra ≤ 0.25 µm).
M2
European sealing only
Sealing exclusively from Kastaş, Trelleborg and other European sealing brands — matched to fluid, speed and temperature per application.
M3
Rod coating ladder
Hard chrome as standard; induction-hardened chrome, nickel-chrome duplex and HVOF tungsten-carbide coating on project basis for the harshest duty.
P1
Tested twice, certified once
100% of production leak-tested at working pressure and at 1.5× working pressure per ISO 10100. Signed, serialised test report with every unit.
P2
Full engineering file
2D + 3D CAD drawings for every single part, buckling calculation for long strokes, and the test report — delivered with every cylinder.
P3
Options that ship
Position sensing, ATEX / IECEx variants, integrated electro-hydraulic actuators. ISPM-15 heat-treated crates, ports plugged, customer RAL topcoat.
[09]Quality & testing · ISO 10100
Every cylinder. Tested, not sampled.
100% of production goes through the ISO 10100:2020 acceptance-test protocol on our in-house benches — welds having already passed NDT Level II inspection, gauges under calibration control. A cylinder that has not passed every step below does not ship.
T1
Proof pressure — 1.5×
Test pressure of 1.5× rated working pressure applied alternately to both ends of the cylinder and held for at least 10 seconds. No permanent deformation, no pressure decay.
T2
Internal leakage
Piston-seal bypass measured at rated pressure in both directions. Leakage beyond the standard's limits fails the unit — it goes back to assembly, not out the door.
T3
External leakage — zero
Rod gland and every static seal inspected under pressure. The acceptance criterion is not "minor weeping": it is zero visible external leakage.
T4
Minimum-pressure travel
The cylinder must stroke smoothly at low pressure — verifying breakout friction, sealing drag and freedom from stick-slip across the full stroke.
T5
Stroke & cushion function
Full stroke length verified against drawing; end-position cushioning performance checked where fitted, in both directions.
T6
Serialised test report
Results recorded against the unit serial number, signed by the test engineer, archived — and shipped with the cylinder alongside its engineering file.
