Single-Acting Teleacopic Hydraulic Cylinders
Product Description
Product Detail
After decades in the hydraulic parts business, when HCIC built the S63MB-8-140 single-acting telescopic hydraulic cylinder, we had one goal: skip the fancy, meaningless specs—every dimension has to solve actual problems on construction sites, mines, and farm fields. Whether it’s mounted on an excavator’s mini arm or an agricultural lift arm, this cylinder’s parameters were tweaked to fit equipment’s installation space and working stroke down to the millimeter. Let’s break down how these specs match up with what you actually need on the job.
HCIC Telescopic Hydraulic Cylinder
High-strength industrial-grade telescopic cylinder for heavy-duty applications
Three-Stage Design: Big Stroke, Even in Tight Spaces
If you work in construction or mining, you know the frustration: equipment has tiny mounting spots, but you need a cylinder that extends far enough to get the job done. That’s exactly what we fixed with the S63MB-8-140:
• 6-inch stage outer diameter + 3 telescopic stages: We went with a 6-inch base outer diameter and a three-stage nested design to keep the cylinder from taking up extra radial space, while the multi-stage stretch gives you the long stroke you need. Think mining machinery telescopic booms or excavator mini arms—tight spaces where you can’t afford to compromise on stroke length or fit. This cylinder slides right in and delivers the reach without forcing you to rework the equipment’s frame.
• 140.35-inch stroke (A): This stroke length isn’t arbitrary. It’s perfect for light and medium-duty gear—long enough to handle lifting, pushing, and reaching tasks, but not so long that it’s a nightmare to install or wastes hydraulic power. Single-stage cylinders often miss this sweet spot, but our three-stage design hits it dead on for real job site needs.
Open/Closed Lengths: Built for How You Actually Use Your Equipment
A cylinder’s retracted and extended lengths aren’t just numbers on a sheet—they have to work with how your machine moves and stores. We set these dimensions for practicality, not just specs:
• 61.62-inch closed length (B) + 201.9-inch open length (C): When it’s retracted, it’s compact enough to keep your machine small for transport or storage—no more struggling to fit equipment on a trailer or in a shed. When fully extended, it reaches far enough to cover the working range of farm lift arms, logistics telescopic forks, and more. It’s not just about fitting the machine’s frame; it’s about fitting how you run your operations day in and day out.
Assembly Specs: Easy to Install, Built to Last
In custom hydraulic setups, small assembly details cause big headaches—misaligned pins, ill-fitting widths, and parts that wear out fast from poor alignment. We designed the S63MB-8-140’s assembly specs to make your life easier:
• 1.5-inch pin diameter (G) + 14.37-inch TR to PIN (J): These pin sizes match the hinge points on most industrial machinery, so you won’t need to machine custom brackets or pins to mount it. The precise pin spacing also makes sure the cylinder bears weight evenly when it moves, so you don’t get premature wear from off-kilter loading—no more replacing parts halfway through a project.
• 3.62-inch width (H) + 12.38-inch width (K) + 1.8-inch diameter (L) + 1.69-inch length (M): We added different width and auxiliary dimensions so the cylinder can mount to different parts of your machine, and pair with accessories like magnification frames and power units. It’s flexible enough to adapt to your existing setup, so you don’t have to redesign your hydraulic system around a single part.

🔧 Custom & Purchase
Q: What is a telescopic multi-stage hydraulic cylinder, and where is it used?
A: A telescopic multi-stage hydraulic cylinder is a long-stroke, compact-retract linear actuator, ideal for applications with limited installation space. It is widely used in dump trucks, garbage trucks, trailer lifts, construction machinery, agricultural equipment, and industrial lifting systems. Our models fit heavy-duty, medium-duty and light-duty working conditions.
Q: How to choose the right telescopic multi-stage hydraulic cylinder for my machine?
A: To select the perfect telescopic multi-stage hydraulic cylinder, provide key parameters: required total stroke, retracted length limit, working pressure, load capacity, mounting type, operating temperature and fluid type. Our engineering team offers free selection and sizing services to match your equipment perfectly.
Q: Can you customize telescopic multi-stage hydraulic cylinders for long stroke applications?
A: Yes, we specialize in custom long-stroke telescopic multi-stage hydraulic cylinders. We support 2-7 stage designs, with maximum stroke up to 8000mm. We optimize cylinder structure, material and sealing system to ensure stability and safety under full extension.
Q: What is the price range of telescopic multi-stage hydraulic cylinders?
A: Telescopic multi-stage hydraulic cylinder prices vary by specifications, stage count, material, customization level and order quantity. We provide detailed and competitive quotes after confirming your stroke, load, pressure, mounting and material requirements. Bulk orders enjoy discounted pricing.
Q: What is the MOQ for telescopic multi-stage hydraulic cylinders?
A: We support a 1-piece MOQ for telescopic multi-stage hydraulic cylinders. You can order single units for replacement, testing, prototype or small-batch projects. Flexible MOQ is available for long-term wholesale and OEM partners.
Q: How long is the lead time for custom telescopic multi-stage hydraulic cylinders?
A: Standard telescopic multi-stage cylinders lead time: 7-10 working days. Customized models: 15-25 working days after design confirmation and deposit. We offer expedited production services for urgent projects, with a lead time as short as 7-10 working days.
⚙️ Performance & After-Sales
Q: How to prevent oil leakage in telescopic multi-stage hydraulic cylinders?
A: We use high-quality imported seals and precision machining to minimize leakage. Regular maintenance includes using clean hydraulic oil, installing oil filters, cleaning piston rods before retraction, and replacing worn seals periodically. We provide complete seal kits for quick on-site replacement.
Q: Can telescopic multi-stage hydraulic cylinders handle high loads and eccentric loads?
A: Our heavy-duty telescopic multi-stage hydraulic cylinders are designed for maximum working pressure up to 350 bar, supporting high-load lifting and pushing. We add reinforced guide sleeves and wear rings to resist eccentric loads (up to 15% of axial load), ensuring stable performance in dump truck and lifting platform applications.
Q: What is the service life of telescopic multi-stage hydraulic cylinders?
A: Under normal operation and proper maintenance, our telescopic multi-stage hydraulic cylinders have a service life of 8-10 years or over 1,000,000 cycles. Service life depends on hydraulic oil quality, working environment, load conditions and regular maintenance.
