Is the dustproof structure suitable for construction sites?

Equipped with multi-stage mud-proof and dustproof wiper rings, which can block sediment and gravel from entering the cylinder interior.

What are the common causes of oil leakage for excavator cylinders?

Seal aging, piston rod surface scratch, long-term overpressure overload operation, poor cleanliness of hydraulic oil.

AI-Powered supplier vetting

SummaryXIAMEN ROCA IMP.& EXP. CO., LTD. is a China-based supplier in Xiamen, Fujian, described variously as a trading company, manufacturer/factory, and group corporation, while another record identifies it as a trading company. Its stated business covers hydraulic cylinders, excavator attachments, metal casting, and hydraulic components, with OEM/custom manufacturing claims. The supplier has 31 employees, valid import/export licensing, 13 years of export experience, and exports representing 71%–90% of total sales. It reports flexible customization and new products launched in the past year. However, it has no available SDK, no in-stock capacity, no overseas warehouse, and no overseas showroom. Certification approval is mentioned in the company description, but no specific certificates are identified. Financial records are referenced by year only, without substantive financial results. Traceability, environmental compliance, fire-drill status, manufacturing-capacity contracts, and customer cases are not...

Supplier typeThe supplier is located in Xiamen, China, and is identified as a trading company in one record and as a trading company/manufacturer/factory among its business-entity classifications. Its company description states that it owns a factory and manufactures hydraulic and metal products, indicating a mixed trading and manufacturing profile rather than a purely documented factory-only structure.

CertificationsThe company description states that its hydraulic cylinders, excavator attachments, metal castings, and hydraulic components have certification approval to meet custom or OEM requirements. Because no certification names, standards, or validity details are provided, the evidence supports a certification claim but does not establish the scope or currency of specific certificates.

R&D capabilityThe supplier reports launching new products during the past year, which is direct evidence of product-development activity. However, it explicitly has no available SDK, so its innovation-related support is not comprehensive across product development and technical integration.

Production capacityThe supplier describes itself as an owned-factory manufacturing enterprise covering hydraulic cylinders, excavator attachments, metal casting, and hydraulic components, and it reports a one-month average lead time in both peak and off-season periods. Conversely, it has no in-stock capacity and its valid manufacturing-capacity contract status is unknown, so production capability is supported but inventory and formal capacity evidence are limited.

Customization capabilityThe supplier explicitly offers flexible customization, and its company description states that its owned factory supports custom or OEM requirements. These two statements directly support its ability to provide customized products.

Product Q&A

Q:What kind of working conditions is this excavator hydraulic cylinder suitable for?

It is specially designed for excavation, crushing, loading and other heavy impact operations of excavators, adapting to muddy, dusty and rugged construction sites.

Q:Why choose double acting structure for excavator cylinders?

Both extension and retraction are hydraulically driven, providing stable bidirectional force to meet the frequent reciprocating movements of excavator boom and bucket.

Q:What is the treatment process of the piston rod?

Oversized thick piston rod, overall quenching treatment plus thick hard chrome plating, impact-resistant, wear-resistant and anti-rust.

Q:Does this cylinder come with built-in buffer function?

Standard double-end hydraulic buffer, which can effectively absorb instantaneous impact force during operation to protect the cylinder and excavator arm.

Q:What brand of sealing parts is equipped as standard?

Imported multi-layer combined high-pressure seals, strong fatigue resistance, low leakage rate under continuous heavy load work.
