Engineering Hydraulic Cylinder

Product Overview

This series of hydraulic cylinders is high-performance hydraulic transmission components designed for engineering machinery, lifting equipment, transportation machinery, and mining machinery. Key features include simple structure, reliable operation, easy assembly/disassembly, and maintenance-friendly design, with support for multiple installation types (external thread, internal spline, flange) and optional buffering devices, making them adaptable to complex working conditions.

Technical Specifications

1. Basic Performance

   • Working Pressure: 16 MPa

   • Cylinder Bore Range: 40-250 mm

   • Speed Ratio (φ): 1.33, 1.46, 2 (corresponding to different thrust and pull force combinations)

   • Thrust & Pull Force: Varies with cylinder bore (D) and rod diameter (d). Maximum thrust reaches 785.4 kN (250 mm bore), and maximum pull force is 378.25 kN.

2. Connection Methods

   • HSGL (External Thread), HSGK (Internal Spline), HSGF (Flange), meeting diverse installation requirements.

3. Piston Rod End Connections

   • Internal Thread with Single Eye Ring: Provides thread specifications from M14×1.5 to M105×3, suitable for various load capacities.

   • External Thread Connection: Includes thread specifications such as M16×1.5 to M105×3.5, ensuring high-precision installation.

   • Critical Dimensions: Mounting hole distance (H1), stroke (S), eye ring bore (φU), etc., comply with international standards to guarantee compatibility and safety.

Design Features

• Modular Design: Supports combinations of multiple speed ratios and connection methods for flexible adaptation to mechanical configurations.

• High-Strength Materials: Integral piston rod design (marked as "Integral Piston Rod" models) enhances fatigue resistance and service life.

• Compact Structure: Optimized dimensions (e.g., minimum stroke limits for flange connections) save installation space.

Applications

• Engineering Machinery: Hydraulic actuators for excavators and loaders.

• Lifting Equipment: Boom extension and hoisting systems.

• Mining Machinery: Power units for rock drills and hydraulic supports.

Notes

1. Connection Dimension Limits:

   • Dimensions marked with "A" apply only to specific speed ratios (e.g., φ=2 or φ=1.7).

   • Stroke for intermediate pins and flange connections must be ≥ the S value in the table to avoid mechanical interference.

2. Thread Compatibility:

   • M2 threads are compatible with speed ratios φ=1.46 and 2; M3 threads are for φ=1.33.
