High-Pressure Hydraulic Cylinder | CDH1MT4/80/45/1000 | 101.6DB2HRLNS34M125 | Pull Rod Type

CDH1 Series High-Pressure Pull Rod Hydraulic Cylinder

Product Overview:

The CDH1 series stands as a high-performance pull-rod hydraulic cylinder engineered for the demanding heavy-duty industrial applications of 2026. This model, CDH1MT4/80/45/1000, combines high-strength materials with precision manufacturing, specifically designed for heavy machinery requiring a long $1000\text{mm}$ stroke with oscillating capabilities. Its robust pull-rod construction ensures stability under high-pressure pulse cycles, making it the ideal power core for metallurgy, presses, and construction equipment.

Core Featured Specifications:

• Main Model: CDH1MT4/80/45/1000 0A1X/B1HGDAWW

• Reference Code: 101.6DB2HRLNS34M125

• Mounting Style: MT4 (Intermediate Trunnion Mount)

Key Technical Advantages:

• $1000\text{mm}$ Precision Long Stroke: Engineered for large-span operations, the barrel is deep-honed to guarantee smooth piston movement across the entire stroke range.

• MT4 Trunnion Positioning: The intermediate trunnion mount effectively reduces rod deflection in long-stroke configurations and absorbs lateral forces generated by system oscillation.

• High-Pressure Pull-Rod Design: Secured by four high-strength tie-rods, sustaining nominal pressures of $25 \sim 35 \text{ MPa}$ with exceptional fatigue resistance in intensive 2026 industrial cycles.

• HGD Advanced Sealing: Equipped with the B1HGDAWW sealing group, offering ultra-low breakaway friction and superior wear resistance to maintain zero internal bypass during long-stroke cycles.

• $80/45 \text{ mm}$ Optimized Ratio: The golden ratio between bore and rod diameters provides massive thrust while maintaining efficient retraction speeds.

Detailed Technical Specifications:

• Piston Ø: $80 \text{ mm}$.

• Rod Ø: $45 \text{ mm}$.

• Stroke: $1000 \text{ mm}$.

• Design Series: A1X Series.

• Mounting Style: MT4 (Intermediate Trunnion).
