CJT70 & CJT140 Series Industrial Tie-Rod Hydraulic Cylinders

Product Overview:

The CJT series represents a premier line of standardized tie-rod cylinders engineered for the high-frequency and high-precision automation requirements of 2026. This collection features various specifications from the 7MPa (CJT70L) long-reach series to the 14MPa (CJT140) heavy-duty series. Known for exceptional sealing stability, low breakaway friction, and ABD adjustable cushioning, these cylinders are the preferred drive components for machine tools, pressing equipment, and industrial power units.

Core Model Specifications:

• CJT140-FA50B200B-ABD-K-11: 14MPa Class, $50\text{mm}$ Bore, $200\text{mm}$ Stroke. Features FA (Front Flange) mounting and ABD (Dual Adjustable Cushioning) for smooth deceleration.

• CJT140-FF40A305N-ANC: 14MPa Class, $40\text{mm}$ Bore, $305\text{mm}$ Stroke. Features FF (Head Circular Flange) mounting, optimized for axially compact environments.

• CJT70L-TC80C290B-ABD-KX51: 7MPa Class, $80\text{mm}$ Bore, $290\text{mm}$ Stroke. Features TC (Intermediate Trunnion) mounting to compensate for cylinder deflection in long-stroke setups.

• CJT140-FA63B150B-ABD-K-11: 14MPa Class, $63\text{mm}$ Bore, $150\text{mm}$ Stroke. Heavy-duty Front Flange mount.

Key Technical Advantages:

• Dual Pressure Coverage: Available in $7 \text{ MPa}$ and $14 \text{ MPa}$ nominal pressures. CJT70L optimizes motion sensitivity at lower pressures, while CJT140 focuses on structural rigidity under heavy loads.

• ABD Cushioning Technology: Models with the ABD suffix include precision adjustable cushion valves that absorb kinetic energy at stroke ends, protecting molds and robotic arms from shock damage.

• Versatile Mounting Profiles:

  • FA/FF (Flange Mount): Delivers superior front-end connection rigidity.

  • TC (Trunnion Mount): Pivoting design balances radial forces on the piston rod during dynamic cycles.

• Premium K-Series Sealing: Utilizing wear-resistant composite seals to maintain zero leakage and zero “stick-slip” motion during intensive 2026 industrial operations.

• Precision Chromed Rods: Hard-chrome plated for superior surface hardness and corrosion resistance, significantly extending seal life.

Detailed Technical Specifications:

• Nominal Pressure: $7 \text{ MPa}$ / $14 \text{ MPa}$.

• Bore Sizes: $40 \text{ mm}, 50 \text{ mm}, 63 \text{ mm}, 80 \text{ mm}$.

• Stroke Range: $150\text{mm}$ to $305\text{mm}$.

• Cushioning: Adjustable on both ends (ABD) / Non-cushioned (ANC).

• Compatible Mediums: Mineral oils, anti-wear hydraulic fluids.
