This page explains how Boom Cylinder is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Hydraulic cylinder that provides linear force to extend and retract the boom section of a hydraulic arm.
Technical details and manufacturing context for Boom Cylinder
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Bore Diameter | 40–200 mm | Determines force output; larger bore for higher force.ISO 6020-2 |
| Rod Diameter | 20–100 mm | Affects buckling strength and retraction speed.ISO 6020-2 |
| Stroke Length | 100–2000 mm | Defines boom reach; longer stroke for larger working range.ISO 6020-2 |
| Operating Pressure | 16–25 MPa | Higher pressure increases force but requires stronger seals.ISO 3320 |
| Maximum Pull Force | 20–400 kN | Calculated from bore and pressure; critical for lifting capacity. |
| Maximum Push Force | 25–500 kN | Higher than pull force due to rod area reduction. |
| Operating Temperature | -20–80 °C | Seal materials degrade outside this range.ISO 5597 |
| Seal Material | NBR–PTFE | NBR for general use, PTFE for high temperature or low friction.ISO 1629 |
| Cylinder Tube Material | ST52–CK45 | ST52 for welded, CK45 for honed seamless.DIN 2391 |
| Rod Material | CK45–42CrMo4 | 42CrMo4 for higher strength and wear resistance.DIN 17200 |
| Surface Treatment | Cr–Ni | Chrome plating for corrosion resistance; nickel for harsh environments.ISO 2081 |
| Weight | 10–500 kg | Affects machine balance and transport. |
| Mounting Type | C–E | Clevis or eye mount for pivoting applications.ISO 6982 |

A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official HCIC website offers excavator boom cylinders with stroke, bore and mounting customised to the machine, and the company profile lists hydraulic cylinder manufacturing in Jinan. Verify fit by machine model, connection dimensions and mutually approved drawings; conflicting figures on the web page are not a delivery commitment.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
It provides linear force to extend and retract the boom section of a hydraulic arm, controlling the boom's angle and reach.
Bore diameter ranges from 40 to 200 mm, and rod diameter from 20 to 100 mm, but these are reference ranges that must be confirmed for the specific model.
Standards such as ISO 6020-2, ISO 3320, ISO 5597, ISO 1629, DIN 2391, DIN 17200, ISO 2081, and ISO 6982 are listed as procurement references. Always verify compliance with the manufacturer.
Materials on file include high-strength alloy steel, chromium-plated steel rod, and polyurethane seals. Specific grades like ST52, CK45, 42CrMo4 are reference options.
