CHM Series Compact Industrial Hydraulic Cylinders

Product Overview:

The CHM series represents a line of heavy-duty compact cylinders engineered for space-constrained environments in 2026 automated machinery. Compared to traditional tie-rod cylinders, it offers a significantly reduced installation footprint. This collection highlights the $50\text{mm}$ Bore specifications, including both standard and short-stroke versions. With a steady $10 \text{ MPa}$ ($100 \text{ bar}$) output, these cylinders are widely utilized in machine tool fixturing, mold clamping, and automated workstations.

Core Model Specifications:

• CHM/50/28/120/CS/00AKPN2: $50\text{mm}$ Bore, $28\text{mm}$ Rod, $120\text{mm}$ Stroke. Features CS (Basic Type) mounting, ideal for compact thrust mechanisms requiring moderate displacement.

• CHM/50/28/50/CS/00AKPN1: $50\text{mm}$ Bore, $28\text{mm}$ Rod, $50\text{mm}$ Stroke. Ultra-short stroke design, perfect for rapid-cycle clamping and positioning tasks.

• Reference Number: TRK02001-1.

Key Technical Advantages:

• Extreme Space Efficiency: The tie-rod-less compact body design ensures a minimal installation footprint, allowing seamless integration into the increasingly precise modular machinery of 2026.

• 100bar Precision Power: Rated at $10 \text{ MPa}$. High-precision honed barrels ensure minimal heat generation and rapid response times during high-frequency operation.

• AKPN Advanced Sealing: Equipped with the latest composite seal components for extreme wear resistance and dust protection. It prevents internal bypass and eliminates “stick-slip” motion at low speeds.

• Double-Acting Reliability: The piston design is pressure-compensated to ensure uniform thrust and retraction forces, extending rod life under asymmetrical load conditions.

• Precision Chromed Rods: Induction-hardened and hard-chrome plated for superior surface hardness, providing excellent corrosion resistance and protection against mechanical scratches from industrial debris.
