What are common failure causes of excavator cylinders?

Stone scratch on rod surface, seal aging, overload leading to barrel deformation.

What' s the difference between our cylinder and ordinary cylinders?

Thicker barrel wall, reinforced welding, wear-resistant rod and high-grade seals for harsh construction sites.

Key features

Double-acting bidirectional hydraulic drive, powerful pushing & pulling force, perfectly matches boom, arm and bucket operation of excavators.

Made of thickened 27SiMn alloy seamless steel tube, strong compression resistance, resistant to deformation under heavy digging loads.

Piston rod adopts overall quenching + thick hard chrome plating, scratch-proof, wear-resistant against rocks and gravel on construction sites.

Imported wear-resistant sealing assembly, stable sealing performance under long-time high-pressure reciprocating work, effectively prevent oil leakage.

Built-in hydraulic buffer structure at both ends, reduce impact during rapid stretching and retracting, protect excavator arm and cylinder body.

Full penetration welding for mounting lugs and cylinder bottom, excellent anti-fatigue property against continuous vibration during excavation.

Strict 100% pressure leakage test and load fatigue test before delivery, stable performance for all-day construction work.

Complete OEM customization: bore size, stroke, installation hole size, oil port specification can be customized for all brand excavators.

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.
