Hydraulic Lifting Cylinders

Cylinder Barrel: This is the main body of the cylinder, which houses the internal components and is subjected to hydraulic pressure.

Piston: The piston is located inside the cylinder barrel and moves back and forth as hydraulic fluid is pumped into and out of the cylinder.

Piston Rod: The piston rod extends from the piston and translates the movement of the piston into the movement of the boom, allowing it to be raised or lowered.

Seals: High-quality seals are essential for maintaining hydraulic pressure and preventing fluid leakage.

End Caps: They help contain hydraulic fluids and often have fluid inlet and outlet ports.

Bushings: These parts are usually located where the piston rod leaves the cylinder and reduces friction and wear.

Topa hydraulic lifting cylinders support loader lift-arm applications, with specifications reviewed against your drawing, equipment reference, or existing cylinder dimensions.

Description

Hydraulic lifting cylinders are responsible for the movement and control of the boom, allowing attachments or loads to be lifted, lowered and positioned. Cylinders work by converting hydraulic pressure into mechanical force to smoothly and precisely control the movement of the moving arm.

They are typically made from high-strength materials such as steel to ensure durability in a variety of operating conditions. The pressure ranges of these cylinders are calibrated to match Bobcat’s operational requirements. They are capable of handling significant loads and performing a variety of tasks efficiently.

Features

Mounting Geometry

Pin diameter, mounting width, and center-to-center dimensions determine how the cylinder fits the lift mechanism. Confirming these details helps identify installation differences before an order is placed.

Stroke and Travel Matching

Stroke and retracted length must work together with the machine’s linkage. A cylinder that fits between the mounts may still provide the wrong travel or interfere with the mechanism at either end of its movement.

Hydraulic Connection Planning

Port threads, orientation, and surrounding clearance affect hose installation. Reviewing these details helps avoid connection changes or hose-routing conflicts during assembly.

Sealing Requirements

Seal selection should reflect the hydraulic fluid, temperature range, pressure, and operating conditions. Rod exposure and contamination should also be considered when defining the sealing and wiper arrangement.

Hydraulic Lifting Cylinders for Bobcat

Topa’s production of Bobcat hydraulic moving arm lift cylinders begins with the selection of quality materials. Components such as cylinder barrels, pistons and piston rods are machined to precise specifications to ensure a perfect fit and smooth operation. Throughout the manufacturing process, each component is meticulously crafted and inspected to ensure compliance with the required standards.

Once assembled, each hydraulic boom lift cylinder undergoes a rigorous quality inspection process. This includes pressure testing, leakage testing. In addition, operational testing simulates the performance of the cylinder in the Bobcat to verify that it meets the precise controls of the machinery.

Topa's Customized Services

Hydraulic Cylinder parts Production Topa

Bore, Rod, and Stroke Review

Submit the required bore, rod diameter, and stroke, together with the application details. These dimensions are reviewed as part of the complete cylinder configuration.

Mounting Configuration

Provide drawings or measurements for the rod-end and base-end mounts. Include pin diameter, mounting width, bushings, and any alignment requirements.

Port Connections

Specify the port thread, size, location, and orientation. Photos of the installed cylinder can help explain hose-routing and access requirements.

Seals and Rod Protection

Share the hydraulic fluid, operating temperature, and external environment. Seal, wiper, and rod-surface requirements can then be discussed for the intended service conditions.

Identification and Finish

Provide your part number, marking requirements, and specified coating or color. Confirm which surfaces require protection or must remain uncoated.

Inspection and Packaging

Define critical inspection points, documentation, packing quantities, and transport protection. Record these requirements with the approved product specification.
