Rexroth CHM Cylinder | CHM/63/45/240 | CHM/50/28/50 | Compact Hydraulic 100bar

CHM Series Compact Industrial Hydraulic Cylinders

Product Overview:

The CHM series represents a premier line of heavy-duty compact cylinders engineered for the streamlined automated machinery of 2026. While maintaining a robust $10 \text{ MPa}$ ($100 \text{ bar}$) power rating, it offers a significantly reduced installation footprint compared to standard tie-rod cylinders. This collection features both the high-capacity $63\text{mm}$ Bore and the versatile $50\text{mm}$ Bore specifications, ideal for mold core pulling, part positioning, and clamping systems.

Core Model Specifications:

• CHM/63/45/240/OI/10AIKPN2: $63\text{mm}$ Bore, $45\text{mm}$ Rod, $240\text{mm}$ Stroke. Features OI (Low-friction) sealing and AIK reinforced configuration, optimized for long-stroke and high-frequency cycles.

• CHM/50/28/50/CS/00AKPN1: $50\text{mm}$ Bore, $28\text{mm}$ Rod, $50\text{mm}$ Stroke. Features CS (Standard) construction with an ultra-compact body, perfect for short-stroke rapid clamping tasks.

Key Technical Advantages:

• Ultra-Compact Footprint: The tie-rod-less design ensures minimal overall length, allowing seamless integration into the high-density modular production lines of 2026.

• 100bar Consistent Power: Rated at $10 \text{ MPa}$. The precision-honed cylinder bore guarantees rapid response times during high-pressure startups.

• AIK/AKPN Sealing Technology: Equipped with the latest PN series composite seals for extreme wear resistance. It prevents internal bypass and eliminates “stick-slip” motion during continuous operations.

• 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 a high-gloss finish, providing superior corrosion resistance and protection against mechanical scratches from machining debris.

Detailed Technical Specifications:

• Nominal Pressure: $10 \text{ MPa}$ ($100 \text{ bar}$).

• Bore Sizes: $50 \text{ mm}$ / $63 \text{ mm}$.

• Rod Sizes: $28 \text{ mm}$ / $45 \text{ mm}$.

• Stroke Range: $50 \text{ mm}$ / $240 \text{ mm}$.

• Seal Material: High-grade Nitrile (NBR) or Viton (FKM).
