Low-Pressure Hydraulic Cylinder Rear Pin

In low-pressure hydraulic cylinders, the back pin refers to the pin or shaft located at the back end of the cylinder. This pin is a connection point or pivot for attaching or mounting the cylinder to other components or equipment. The following is some information about the low-pressure hydraulic cylinder rear pin:

Design and construction of the low-pressure hydraulic cylinder

Rear pin: The rear pin is usually a sturdy metal pin or shaft that extends through the rear end of the hydraulic cylinder. Its purpose is to provide a secure connection and pivot point for the cylinder.
Mounting hole: The rear pin is inserted through a mounting hole or bracket on the cylinder housing or rear flange. These mounting holes are aligned with the corresponding holes or brackets on the equipment or structure to which the cylinder is attached.
Retaining mechanism: The rear pin can be secured using retaining clips, bolts, or other fasteners to prevent accidental disconnection or movement.

Applications Of Low-Pressure Hydraulic Cylinder Rear Pin:

  • Low-pressure hydraulic cylinders with rear pins are used in a variety of industries and applications, especially in systems operating at lower hydraulic pressures.
  • They are commonly used in industrial machinery, mobile devices, and other systems where space limitations or specific installation requirements exist.
  • These cylinders are suitable for material handling, lifting mechanisms, conveying systems, and other equipment that requires linear force or movement.

Mounting and Connection Of Low-Pressure Hydraulic Cylinder Rear Pin:

  • Mounting the Cylinder: The rear pin allows for direct attachment of the hydraulic cylinder to other equipment or structural elements. The pin is inserted through the mounting holes or brackets on the cylinder and the mating holes or brackets on the equipment or structure.
  • Fastening the Rear Pin: Once the rear pin is inserted through the mounting points, it is typically secured in place using retaining clips, bolts, or other fasteners. These fasteners ensure a stable and rigid connection between the cylinder and the mating surface.

How To Rebuild Hydraulic Cylinder?

Rebuilding a hydraulic cylinder involves removing the cylinder, inspecting and replacing worn or damaged parts, reassembling the cylinder with new parts, and testing it for proper operation. Here is a general overview of the process:

  1. Gather Required Tools and Parts: Before starting the rebuild process, gather the necessary tools and replacement parts, including seals, o-rings, gaskets, and any other components specific to your hydraulic cylinder model.
  2. Cylinder Removal: Disconnect the hydraulic cylinder from the system or equipment it is installed in. Follow proper safety procedures and use appropriate lifting equipment if needed.
  3. Cylinder Disassembly: Carefully disassemble the cylinder, taking note of the order and orientation of the components as you remove them. This may involve removing the end caps, piston, piston rod, seals, and other internal components.
  4. Component Inspection: Inspect each component for wear, damage, or degradation signs. Pay close attention to seals, o-rings, and other rubber components, as they are commonly replaced during a rebuild. Replace any worn or damaged parts with new ones.
  5. Cylinder Cleaning: Thoroughly clean all components using an appropriate cleaning agent to remove dirt, debris, and hydraulic fluid residue. Ensure that all ingredients are dehydrated before reassembly.
  6. Seal Installation: Install new seals, o-rings, and gaskets in their respective positions within the cylinder. Ensure proper alignment and orientation according to the manufacturer’s specifications.
  7. Reassembly: Begin reassembling the cylinder, following the reverse order of disassembly. Lubricate the seals and o-rings with a compatible hydraulic fluid or assembly lubricant as you reassemble the components.
  8. Torque and Tighten: Use the manufacturer’s recommended torque values to tighten bolts, nuts, and fittings to the appropriate specifications. Ensure that all connections are secure but avoid over-tightening, which can damage components.
  9. Testing: Re reconnect the cylinder to the hydraulic system or equipment once the cylinder is reassembled. Test the cylinder for proper operation, including extension, retraction, and pressure-holding capabilities. Check for any leaks and address them if necessary.
  10. System Fluid Replacement: If required, replace the hydraulic fluid in the system with clean, compatible fluid following the manufacturer’s guidelines.
