Hydraulic Cylinder Types We Customize
Different machines require different hydraulic cyinder structures. ZHY manufactures custom hydraulic cyinders accordingto drawings, samples, installation requirements, and working conditions, helping you match the right cylinder type before production.
Double-Acting Hydraulic Cylinders
Double-acting hydraulic cylinders provide controlled movement in both extension and retraction directions, making them suitable for equipment that requires stable force and repeatable operation.
Telescopic Hydraulic Cylinders
Telescopic hydraulic cylinders are used when long stroke movement is required within limited installation length, such as dump trucks, lifting systems, trailers, and special machinery.
Welded Hydraulic Cylinders
Welded hydraulic cylinders are suitable for heavy-duty machinery, construction equipment, agricultural machines, sanitation vehicles, and compact installation spaces where strength and durability are important.
Tie Rod Hydraulic Cylinders
Tie rod hydraulic cylinders are often used in industrial equipment, automation systems, presses, lifting devices, and applications that require easier maintenance and stable structure.
Application-Based Custom Hydraulic Cylinder Solutions
Different hydraulic applications require different cylinder structures, sealing systems, pressure resistance, and surface protection. ZHY custom hydraulic cylinders can be engineered according to operating environments, movement direction, load conditions, and hydraulic system requirements across various industries.
Custom Hydraulic Cylinders for Excavator & Loader
Excavator hydraulic cylinders operate under heavy loads, shock, dust, and continuous digging cycles. Side loading, rod scoring, seal wear, and pressure loss can reduce equipment efficiency. ZHY manufactures rugged cylinders with precision machining, wear-resistant rods, reliable sealing systems, and stable performance for demanding construction applications.
Custom Cylinders for Aerial Work Platforms
AWP require smooth lifting, accurate positioning, and reliable presure holding performance at working height. Frequent extension, outdoor exposure, and continuous operation may cause leakage, instability, and premature wear. ZHY supplies high-quality cylinders with precision sealing, corrosion-resistant surfaces, and stable hydraulic performance for safe lifting operations.
Custom Cylinders for Agricultural Machinery
Agricultural machinery operates in mud, moisture, dust, and changing weather conditions. Corrosion, contamination, vibration, and seal damage can shorten cylinder service life. ZHY provides corrosion-resistant cylinders with durable sealing systems, precision machining, and reliable performance for tractors, harvesters, sprayers, and other farming equipment.
Custom Cylinders for Marine Applications
Marine hydraulic cylinders must withstand seawater, salt spray, humidity, and harsh offshore environments. Corrosion and seal failure can affect equipment reliability and maintenance costs. ZHY manufactures marine cylinders using corrosion-resistant materials, hard chrome plated rods, and dependable sealing systems for long-term service.
Custom Cylinders for Forklifts & Attachments
Forklifts and attachments require smooth lifting, tilting, clamping, and side-shifting under frequent operating cycles. Leakage, pressure loss, and seal wear may reduce handling efficiency. ZHY produces durable cylinders with precision machining, stable sealing performance, and long service life for forklifts and material handling attachments.
Custom Cylinders for Sanitation Vehicle
Sanitation vehicles perform continuous lifting, tipping, and compaction under heavy-duty outdoor conditions. Frequent operation, contamination, and vibration can accelerate seal wear and cylinder failure. ZHY manufactures heavy-duty cylinders with welded construction, corrosion-resistant protection, reliable sealing, and stable hydraulic performance for waste collection equipment.
We Help You Avoid These Problems
| Common Problem | Possible Cause | How ZHY Helps you Avoid It |
|---|---|---|
| Oil Leakage | Oil leakage may happen when the seal material, seal structure, piston rod surface, machining tolerance, or pressure rating is not properly matched to the actual working condition. | As a custom hydraulic cylinder manufacturer, ZHY reviews seal type, seal brand options, oil type, working pressure, temperature, rod surface treatment, and leakage testing requirements before production. |
| Weak Lifting or Pushing Force | If the bore size, rod diameter, wall thickness, or working pressure is not correctly selected, the cylinder may fail to provide enough force under real machine load. | ZHY helps confirm bore size, stroke length, rod diameter, pressure rating, load direction, and application environment to support more stable force output. |
| Installation Mismatch | Wrong closed length, extended length, mounting distance, oil port position, thread type, or rod end connection can cause installation failure. | As a custom hydraulic cylinder supplier, ZHY checks drawings, samples, mounting methods, clevis dimensions, flange structure, trunnion position, and oil port direction before manufacturing. |
| Rod Corrosion | Outdoor, marine, humid, dusty, or chemical environments can damage the piston rod surface and shorten cylinder service life. | ZHY recommends suitable piston rod material, chrome plating thickness, surface coating, and corrosion-resistant protection based on the working environment. |
| Dimensional Inconsistency | Poor dimensional tolerance and unstable machining quality often create assembly difficulties, abnormal wear, vibration, and sealing problems. | We apply strict inspection standards and precision manufacturing processes to help maintain consistent bore size, rod concentricity, and component compatibility for smoother hydraulic cylinder operation. |
| Unstable Movement | Unstable extension or retraction may be caused by poor internal matching, unsuitable seals, insufficient guiding support, incorrect oil flow, or machining inconsistency. | ZHY controls machining accuracy, assembly quality, seal matching, guide component selection, and stroke movement testing before shipment. |
| Early Cylinder Failure | Early failure may result from wrong material selection, weak welding, insufficient pressure testing, unsuitable coating, or ignoring the real operating frequency. | As a custom hydraulic cylinder factory, ZHY supports material review, welding control, dimensional inspection, pressure testing, and export packing for OEM and wholesale orders. |
| Short Service Life | A cylinder may wear out faster if pressure, working cycles, surface treatment, seal performance, and application conditions are not considered together. | ZHY helps you review the full working condition instead of only copying cylinder size, reducing the risk of repeated replacement and maintenance. |
