Piston Service Kit with Low Friction Seals for Parker HMI & HMD Series Tie Rod Cylinders
Product Overview
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
A: Sure. Show us the drawing, we will quote for you soonest.
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.
1. Eliminate Stick-Slip for Precision Motion
Low-friction composite seals maintain steady sliding force at ultra-low piston speeds, avoiding jerky movement and positioning errors in precision automation, CNC clamping and synchronous lifting equipment.
2. Reduce System Energy Consumption
Lower sliding friction reduces hydraulic load loss, decreasing power draw from hydraulic power units and supporting energy-saving production line operation.
3. Suppress Heat Buildup & Extend Seal Lifespan
Friction heat is drastically reduced during high-cycle continuous operation, slowing elastomer aging, permanent compression set and seal hardening to extend maintenance intervals.
4. Stable Low Internal Cross-Chamber Leakage
Precision molded bidirectional sealing lips maintain consistent fluid blocking performance under variable pressure, ensuring stable cylinder thrust and repeatable positioning accuracy.
5. Optimized Side Load Adaptability
Matched low-friction PTFE wear rings evenly distribute radial side loads common in tie rod cylinder installations, preventing uneven seal lip wear and early failure.
- Bidirectional low-friction composite piston seals (core PTFE sliding surface + HNBR elastomer backing)
- Low-drag filled PTFE fabric wear guide rings, engineered to reduce radial friction between piston and honed cylinder tube
- Lightweight PEEK anti-extrusion backup rings to prevent seal edge deformation under pressure fluctuations
- Low-friction HNBR static O-rings for auxiliary piston end sealing
- Special low-viscosity assembly lubricant compatible with PTFE composite seals
- Official Parker operation manual covering disassembly, seal installation and torque standards for HMI/HMD tie rod cylinders
