Frequently Asked Questions (FAQ)

PRODUCT & SPECIFICATIONS

Q1: What are the main differences between the front and rear support seats?

A: The front support seats are manufactured using precision investment casting, which allows for complex geometries, better surface finish, and dimensional accuracy for proper cylinder alignment. The rear support seats are produced via hot forging, providing superior grain structure, higher impact resistance, and optimal strength for handling primary thrust loads. Both components are engineered as a complementary set to distribute operational stresses effectively.

Q2: What materials are typically used? Can I request alternative materials?

A: Our standard materials are:

• Cast Components: ASTM A148 Grade 80-50 Cast Steel

• Forged Components: ASTM A668 Class E Forged Steel

• Yes, we offer material alternatives including ductile iron, stainless steel (304/316), and alloy steels (4140, 4340) for specific requirements such as corrosion resistance, extreme temperatures, or enhanced strength-to-weight ratios. Please discuss your application environment during inquiry.

Q3: Are these support seats compatible with international cylinder standards?

A: Absolutely. Our standard designs are compatible with:

• NFPA (National Fluid Power Association) tie-rod cylinder dimensions

• ISO 6020/6022 (Hydraulic fluid power – Mounting dimensions)

• Common European (DIN/ CETOP) and Asian (JIS) standards
  Custom mounting patterns can be manufactured to match any OEM specification.

PERFORMANCE & APPLICATION

Q4: What is the expected service life?

A: Under normal operating conditions within specified load limits, our support seats typically last 2-3 times longer than conventional single-process (e.g., fully machined or standard cast) components. Actual lifespan depends on factors like load cycles, shock loading, alignment maintenance, and environmental conditions. We provide FEA-based life estimation for your specific application upon request.

Q5: What are the temperature and environmental limits?

A: Standard units are rated for continuous operation from -40°C to +200°C. For extreme environments, we offer:

• Low-temperature variants with certified impact toughness for arctic applications

• Corrosion-resistant versions with specialized coatings or stainless materials

• High-temperature treatments for applications near engines or furnaces

Q6: Can these support seats be used with both hydraulic and pneumatic cylinders?

A: Yes. The design is optimized for high-pressure hydraulic systems (up to 350 Bar/5000 PSI for standard units), but they are equally suitable for heavy-duty pneumatic applications where vibration, side loads, or long stroke lengths are concerns. Please specify your operating pressure during selection.

ORDERING & CUSTOMIZATION

Q7: Are these sold as individual pieces or as a complete set?

A: We typically recommend and supply them as a matched Front & Rear Set to ensure optimal performance and load distribution. However, individual components (front only or rear only) can be ordered as replacement parts, provided the mating component’s specifications are supplied for compatibility verification.

Q8: What level of customization is available?

A: We offer extensive customization:

• Dimensional Modifications: Bore sizes, mounting hole patterns, pilot diameters

• Material & Finish: Alternative materials, hardness, plating, painting

• Features: Addition of lubrication ports, sensor mounts, alignment aids

• Branding: Laser etching or casting of part numbers, logos
  Send us your drawings or CAD models for a quotation.

Q9: What information do you need to provide a quotation or recommendation?

A: To serve you best, please provide:

1. Cylinder make, model, and bore/rod diameters

2. Operating pressure and type (hydraulic/pneumatic)

3. Load details (static, dynamic, shock loads)

4. Mounting style and interface drawings (if available)

5. Application environment (indoor, outdoor, corrosive, temperature)

6. Annual quantity requirements

Q10: What quality certifications do you hold?

A: Our manufacturing is certified under ISO 9001:2015. We provide Material Test Certificates per EN 10204 3.1 as standard. Additional testing and certifications (CE marking, specific NDT reports) are available upon request.
