CLL Series Lock Nut Hydraulic Cylinder

This versatile lifting tool uses pressurized hydraulic fluid to extend its ram and lift heavy loads. Its simple single-acting design means hydraulic pressure only powers the lifting stroke; a built-in spring return mechanism automatically retracts the ram when pressure is released. This results in a robust, compact, and cost-effective jack ideal for common lifting, positioning, and maintenance tasks across automotive, industrial, and construction applications. Its reliability and ease of use make it a fundamental tool for safely handling substantial weights.

Load capacity: 50-800 ton

Stroke: 42-155mm

Maximum working pressure: 70 MPa

Features:

  1. Single acting, load return.
  2. Painted surface has stronger corrosion resistance.
  3. Nut locking makes the load safer and can maintain the load absolutely safely for a long time.
  4. All models are equipped with NPT3/8″ quick connector and dust cap.
  5. Overflow hole and limited stroke function.
  6. Special guide ring design provides support for the pressure of offset center and effectively prevents direct friction between piston rod and inner wall to reduce wear and extend the service life of hydraulic cylinder.
  7. High hardness, easy to replace grooved top plate, durable.
  8. Double-acting mechanical self-locking can be customized according to customer needs.

Frequently Asked Questions – Hydraulic Cylinder

Our hydraulic cylinders cover a torque range from 100 ton to 1000 ton, suitable for various heavy industrial tasks.

Yes, but please use synchronous lifting system.

Ensure:

  • All jacks are same model & capacity.

  • Load is evenly distributed.

  • The lifting surface is level and stable.

The loading capacity and stroke are vey necessary. Besides, is it single acting or double acting, lock nut type or standard. Please provide as many information as possible.

Service intervals depend on usage:

  • Industrial daily use: Inspect oil/seals monthly; full service yearly.

  • Occasional use: Check oil level & function every 6 months.
    Always clean the ram after use and store in a dry place.

Use only ISO VG 32 or VG 46 hydraulic oil (AW or anti-wear grade preferred).
