Project Information
Project Name: Compact Hydraulic Cylinder for Electrical Equipment
Applied Equipment: Clamping Machines
Order Code: CX 32x16x10-14MPa
Operating Pressure: 14MPa
Cylinder Type: Double-Acting Hydraulic Cylinder
Project Background & Requirements Overview
This was a new compact cylinder development project for electrical clamping equipment.
The customer required a very small hydraulic cylinder with a short stroke and stable pulling performance in limited installation space.
Initial Customer Request
- Cylinder volume target: very compact (reference size around 50 mm³ class)
- Stroke length: 10mm
- Pulling-focused application
- Back-mounted hydraulic inlets
- Desired pressure from customer side: 200 bar (200 kg/cm²)
- Need for either single-acting or double-acting structure
Engineering Goal
Our objective was to deliver a design that fully matched the customer’s installation and performance needs, while also optimizing key technical parameters from a professional hydraulic engineering perspective for better reliability and manufacturability.
II. Customer’s Special Requirements (Customization)
Based on communication with the customer, the main customization points were:
- Extremely compact cylinder envelope
- Short stroke (10mm) with stable output
- Back-mounted ports for tight machine layout
- Pressure optimization recommendation
- Customer initially requested 200 bar
- We recommended 140 bar (14MPa) to improve overall balance of compactness, sealing reliability, and service life
- Double-acting design to ensure controlled motion in both directions
III. Solution & Design Description
According to the project requirements, we provided a customized standard-based compact solution:
- Type: Double-acting hydraulic cylinder
- Bore: 32mm
- Rod: 16mm
- Stroke: 10mm
- Thread: M16
- Oil Port Layout: Back-mounted
- Working Pressure: 14MPa
Key Design Highlights
- Compact structure: suitable for limited mounting space in electrical clamping systems
- Back port configuration: simplifies pipeline routing in dense equipment layouts
- Optimized pressure level (14MPa): better sealing and durability in a micro-compact cylinder format
- Standardized architecture: helps reduce cost and improve lead time for batch production
IV. Project Result & Application Effect
After prototype production and validation, the cylinder achieved the expected performance in clamping machine operation:
- Stable bidirectional actuation
- Reliable pulling motion under target pressure
- Smooth integration into compact equipment structure
- Good manufacturability for production scaling
V. Customer Feedback
- Feedback Summary: Prototype/sample approval completed successfully, followed by batch purchase.
- The customer confirmed that the compact size and revised technical parameters matched the equipment requirements well.
