Our Standard Hydraulic Piston Rod Quality (HRQ) Bars represent the pinnacle of precision manufacturing, developed through advanced processes that ensure superior dimensional accuracy and mechanical properties. These components undergo specialized hardening, grinding, and hard chrome plating processes, resulting in products that exceed industry expectations for durability and performance.
Anwendungen
Standard Hydraulic Piston Rod Quality (HRQ) Bars serve critical functions across numerous industries. They are essential components in hydraulic systems for industrial machinery, construction equipment (including excavators and loaders), automotive manufacturing systems, material handling equipment (such as forklifts), agricultural machinery, and precision manufacturing systems. Their robust construction ensures reliable performance in high-pressure environments ranging from 16MPa to 70MPa.
Our Standard Hydraulic Piston Rod Quality (HRQ) Bars feature exceptional surface hardness reaching 850HV minimum through advanced hardening processes. The precision grinding achieves surface roughness values as low as Ra0.2μm, significantly reducing friction and wear on sealing components. Our proprietary chrome plating technology provides corrosion resistance and enhanced durability, with chrome thickness exceeding 25 microns. The manufacturing process includes roller burnishing treatment that improves fatigue strength by up to 25% and increases surface hardness by approximately 30%.
Technical Specifications
We produce Standard Hydraulic Piston Rod Quality (HRQ) Bars in diameters ranging from 6mm to 300mm with lengths up to 16 meters. Our products maintain exceptional straightness (0.2/1000mm) and comply with ISO f7 tolerance standards. Materials include high-grade carbon steels (CK45, SAE1045), alloy steels (42CrMo, 40Cr), and specialty materials for specific environmental conditions. The chrome plating thickness is meticulously controlled to ensure consistent performance across all products.
Variants Available
Our Standard Hydraulic Piston Rod Quality (HRQ) Bar product line includes solid construction rods, hollow piston rods, stainless steel variants, custom-length specimens, and specialty rods with unique end treatments (threaded ends, flanged designs). We also offer rods with advanced surface treatments including double-layer plating, composite nickel/chrome plating, and ceramic surface treatments for extreme operating conditions.
With decades of specialized experience, we have perfected the art of piston rod manufacturing. Our facilities incorporate state-of-the-art plating systems that reduce environmental impact while enhancing product quality. We maintain IATF 16949 quality management systems and offer comprehensive technical support throughout the design and specification process.
