CJT70 & CJT140 Series Industrial Tie-Rod Hydraulic Cylinders

Product Overview:

The CJT series represents a premier line of tie-rod hydraulic cylinders engineered for 2026 high-frequency industrial applications, available in 7MPa (CJT70) and 14MPa (CJT140) pressure classes. This collection highlights specifications from the compact FA40 to the massive TC125. Known for exceptional sealing stability, low-friction startup, and versatile mounting, these cylinders are the ideal drive components for machine tools, injection molding machines, and industrial presses.

Core Model Specifications:

• CJT140-FA40B165-BD: 14MPa Class, $40\text{mm}$ Bore, $165\text{mm}$ Stroke. Features FA (Front Rectangular Flange) mounting, ideal for axial force fixed precision tasks.

• CJT140-TC125B240B/340B-ABD: 14MPa Class, $125\text{mm}$ Bore, $240\text{mm}/340\text{mm}$ Stroke. Features TC (Intermediate Trunnion) mounting to balance cylinder weight in long-stroke configurations.

• CJT70-FA40C405B-ABD: 7MPa Class, $40\text{mm}$ Bore, $405\text{mm}$ Stroke. Designed for medium-pressure long-reach actuation.

Key Technical Advantages:

• Dual Pressure Class Coverage: Offers both $7 \text{ MPa}$ and $14 \text{ MPa}$ nominal pressures to meet requirements from light automation to heavy-duty industrial drives.

• Versatile FA/TC Mounting:

  • FA (Front Flange): Ensures maximum rigidity at the rod end.

  • TC (Intermediate Trunnion): Pivoting design reduces lateral deflection of the piston rod during long-stroke extension.

• ABD Advanced Cushioning: The -ABD suffix indicates integrated adjustable terminal cushioning, which smoothly absorbs kinetic energy to minimize impact and extend seal life.

• Low-Friction Sealing: Utilizes wear-resistant composite seals to maintain ultra-low breakaway pressure, effectively eliminating “stick-slip” motion during intensive 2026 production cycles.

• Reinforced Tie-Rod Construction: Precision-tempered rods and barrels ensure zero fatigue deformation under high-pressure cycles, enhancing overall system stability.

Detailed Technical Specifications:

• Nominal Pressure: $7 \text{ MPa}$ (CJT70) / $14 \text{ MPa}$ (CJT140).

• Bore Sizes: $40 \text{ mm}$ to $125 \text{ mm}$.

• Stroke Range: $165\text{mm}, 240\text{mm}, 340\text{mm}, 405\text{mm}$.

• Cushioning: Adjustable on both ends (ABD).

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