Industry-Verified Manufacturing Data (2026)

Cylinder Body

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Cylinder Body used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Cylinder Body is characterized by the integration of Cylinder Tube and End Cap / Gland. In industrial production environments, manufacturers listed on CNFX commonly emphasize Aluminum Alloy construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The main structural housing of a soft-close damper that contains the piston and hydraulic fluid.

Technical details and manufacturing context for Cylinder Body

Definition
The cylinder body is the primary structural component of a soft-close damper, serving as the sealed chamber that houses the piston, hydraulic fluid, and internal valving. It provides the necessary containment for the controlled fluid displacement that enables the damper's smooth, decelerating closing action.
Working Principle
The cylinder body acts as a pressure vessel. As the damper's piston rod is compressed or extended, it forces hydraulic fluid through internal orifices and valves within the cylinder body. The resistance created by this fluid flow through the restricted passages generates the damping force, converting kinetic energy into heat and providing the soft-close functionality.
Common Materials
Aluminum Alloy, Stainless Steel
Technical Parameters
  • Inner diameter of the cylinder bore, critical for piston fit and fluid displacement volume. (mm) Customizable
Components / BOM
  • Cylinder Tube
    Forms the main bore for piston travel and fluid containment.
    Material: Aluminum Alloy
  • End Cap / Gland
    Seals the end of the cylinder and guides the piston rod.
    Material: Stainless Steel
  • Mounting Bracket
    Provides attachment points for installing the damper assembly.
    Material: Steel
Engineering Reasoning
0-25 bar hydraulic pressure, -20°C to 120°C temperature
35 bar internal pressure causing permanent deformation, 150°C causing seal degradation
Design Rationale: Yield strength exceedance at 35 bar (aluminum alloy 6061-T6: 276 MPa yield), thermal expansion mismatch at 150°C (aluminum: 23.1 μm/m·K vs seals: 150-200 μm/m·K)
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Piston scoring leading to internal leakage exceeding 5 cm³/min
Strategy: Integrate 10 μm absolute filtration with differential pressure monitoring at 0.5 bar threshold
Trigger Thermal cycling between -20°C and 120°C at 10 cycles/hour
Mode: Seal hardening and microcrack formation at 10⁴ cycles
Strategy: Implement nitrile rubber seals with 150°C continuous rating and 0.5 mm radial compression design

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Cylinder bore scoring
Cause: Contamination ingress (dust, metal particles) or inadequate lubrication leading to metal-to-metal contact and abrasive wear on the bore surface.
Rod seal leakage
Cause: Seal degradation from chemical incompatibility, excessive heat, or misalignment causing extrusion damage and hydraulic fluid loss.
Maintenance Indicators
  • Audible hissing or squealing during operation indicating seal failure or air ingress
  • Visible hydraulic fluid weeping around rod gland or cylinder mounting points
Engineering Tips
  • Implement proactive contamination control with proper filtration (ISO 4406 compliance) and regular fluid analysis
  • Ensure correct cylinder alignment during installation and use rod wipers to prevent external contaminant ingress

Compliance & Manufacturing Standards

Reference Standards
ISO 6020-1: Hydraulic fluid power - Mounting dimensions for single rod cylinders, 16 MPa series ANSI/NFPA T3.6.7 R1-2015: Fluid power cylinders - Bore and rod diameter and mounting dimensions DIN ISO 3320: Fluid power systems and components - Cylinder bores and piston rod diameters - Metric series
Manufacturing Precision
  • Bore diameter: +/-0.02 mm
  • Parallelism of mounting surfaces: 0.1 mm per 100 mm length
Quality Inspection
  • Pressure test: 1.5 times maximum working pressure for 2 minutes
  • Dimensional verification using CMM (Coordinate Measuring Machine)
