Key Technical Advantages (Applicable to Both Models)
1. High-Strength Tie-Rod Construction & Compact Design
The HMI Series features a robust four-tie-rod construction securing the head, cap, and barrel into a single rigid assembly. This proven design provides excellent shock and vibration resistance while maintaining a compact footprint. Tie rods feature rolled threads for significantly improved fatigue strength and anti-loosening performance.
2. Multiple Rod Size Options & Versatile Mounting
The HMI Series offers up to three rod diameter options per bore size, enabling precise selection based on thrust/pull force requirements and column strength considerations. A wide range of standard mounting styles (including SD, LA, LB, FA, FB, CA, CB, TC) accommodates applications from simple clevis mounting to complex flange fixation.
3. High-Performance Sealing System & Extended Service Life
Parker’s proprietary sealing technology features piston seals and rod seals manufactured from high-performance polyurethane and nitrile materials. The rod seal incorporates a multi-lip design with an integral wiper seal, effectively preventing external contaminant ingress while ensuring a clean, dry rod surface. Bi-directional piston seals deliver leak-free performance, reducing downtime and improving system efficiency.
4. Wide Temperature Range & Fluid Compatibility
Depending on seal material selection, HMI Series cylinders operate reliably across a broad temperature range from -20°C to +150°C. Seal materials are compatible with multiple hydraulic media, including standard mineral oils, water-glycol fire-resistant fluids, and synthetic hydraulic fluids, meeting diverse industry and application requirements.
5. Complete Drop-In Interchangeability & Standardized Interfaces
Strictly manufactured to original Parker HMI Series design specifications and ISO 6020/2 international standards. Mounting interface dimensions, port configurations, and rod end thread standards align flawlessly with original factory specifications. Field replacement requires zero piping modifications or foundation changes, dramatically minimizing equipment downtime.

Expert Maintenance Tips
1. Pre-Installation Inspection & Preparation
Before installation, verify that the model code matches the order requirements and inspect the cylinder barrel and rod surface for transportation damage. The piston rod surface should be smooth, free of scratches and corrosion. Drain the anti-rust oil from the cylinder interior and flush with clean hydraulic fluid before installation.
2. Mounting Concentricity & Side Load Control
Ensure the cylinder axis remains concentric with the load motion direction during installation to avoid excessive side loading. Excessive side loads accelerate wear on rod seals and guide bushings, shortening service life. Use alignment pins or adjustment shims to ensure installation precision.
3. Piping Connections & Air Bleeding
Ensure piping is clean and free of contaminants before connecting to the cylinder. Before first operation, purge all air from the cylinder interior through preset bleed ports (if available) or by slowly cycling the cylinder through full stroke multiple times. Inadequately purged cylinders will exhibit stick-slip behavior during operation, compromising control accuracy.
4. Fluid Cleanliness Management
Recommended system fluid cleanliness is ISO 18/16/13 or better. Install filters with minimum 10μm rating upstream of the cylinder inlet port to prevent contaminants from entering and damaging rod seals and cylinder bore surfaces.
5. Scheduled Inspection & Seal Replacement
Perform comprehensive performance inspections every 2000 operating hours or annually (whichever comes first), including external leakage inspection, rod surface inspection, and motion smoothness verification. Always use genuine Parker service kits when replacing seals, and verify that seal materials are compatible with the system fluid type.
