CJT70L Series Heavy-Duty Industrial Hydraulic Cylinders

Product Overview:

The CJT70L series is a $7\text{MPa}$ class tie-rod hydraulic cylinder engineered for the high-frequency industrial production lines of 2026. This range covers core specifications from the compact CJT70L-CB40 to the heavy-duty CJT70L-TC80. Known for exceptional sealing stability, ultra-low breakaway pressure, and long-life design, it is widely utilized in injection molding, die-casting, and automated assembly systems.

Core Model Specifications:

• CJT70L-TC80C290B-ABD-KX51: $80\text{mm}$ Bore, $290\text{mm}$ Stroke. Features TC (Intermediate Trunnion Mount) for superior pivoting stability.

• CJT70L-CB40C100B-ABD-EFKMX52-20: $40\text{mm}$ Bore, $100\text{mm}$ Stroke. Features CB (Rear Clevis Mount) for flexible articulated power transmission.

Key Technical Advantages:

• 7MPa Class Precision Power: Optimized for medium-pressure cycles. The robust tie-rod structure maintains extreme fatigue strength during intensive 2026 reciprocating operations.

• Versatile TC/CB Mounting Styles:

  • TC (Trunnion Mount): Reduces rod-end deflection in medium-to-long stroke applications.

  • CB (Clevis Mount): Simplifies integration within oscillating mechanisms and pivots.

• ABD Advanced Cushioning: Integrated adjustable terminal cushioning absorbs kinetic energy at the stroke ends, significantly reducing vibration and extending seal life.

• KX51/X52 Low-Friction Engineering: Optimized for high-performance control, reducing initial resistance and ensuring smooth, “stick-slip” free motion even at ultra-low speeds.

• Precision Chromed Rods: Rods are induction-hardened and hard-chrome plated, providing excellent corrosion resistance and mechanical impact protection.

Detailed Technical Specifications:

• Bore Sizes: $40 \text{ mm}, 80 \text{ mm}$.

• Stroke Range: From $100 \text{ mm}$ to $290 \text{ mm}$.

• Rated Pressure: $7 \text{ MPa}$.

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

• Compatible Mediums: Mineral oils, water-glycols, and synthetic lubricants.
