How to Measure Forklift Hydraulic Cylinder

Forklift Hydraulic Cylinder

The forklift hydraulic cylinder is an integral part of the forklift's lifting mechanism. It is responsible for lifting and lowering the load. In order to achieve optimal performance, it is essential to measure the hydraulic cylinder correctly. This article will guide you through the process of measuring forklift hydraulic cylinder.

1. Determine the Bore Size

The bore size is the diameter of the piston inside the cylinder. To measure the bore size, you need to remove the cylinder from the forklift. Measure the diameter of the piston with a caliper. Make sure to measure the piston at the widest point and record the measurement in millimeters.

2. Measure the Rod Size

The rod size is the diameter of the rod attached to the piston. To measure the rod size, measure the diameter of the rod with a caliper. Make sure to measure the rod at the widest point and record the measurement in millimeters.

3. Determine the Stroke Length

The stroke length is the distance the piston travels inside the cylinder. To measure the stroke length, place the cylinder on a flat surface and extend the rod to its maximum length. Measure the distance between the mounting surface and the end of the rod. Record the measurement in millimeters.

4. Calculate the Volume

Once you have measured the bore size, rod size, and stroke length, you can calculate the volume of the hydraulic cylinder. Use the formula:

Volume = (¦Ð/4) x bore2 x stroke length

where ¦Ð is the mathematical constant pi (3.14159) and bore is the diameter of the piston in meters.

By measuring the forklift hydraulic cylinder correctly, you can ensure optimal performance and prolong the life of the hydraulic system.

Forklift Hydraulic Cylinder in use


1. What is a forklift hydraulic cylinder?

A forklift hydraulic cylinder is a device that converts fluid power into mechanical force and motion. It consists of a piston and rod assembly inside a cylindrical housing.

2. Why is it important to measure the forklift hydraulic cylinder?

Measuring the forklift hydraulic cylinder is important to ensure that the cylinder is the correct size for the forklift's hydraulic system. An incorrect size cylinder can cause performance issues and premature failure.

3. Where can I purchase a forklift hydraulic cylinder?

You can purchase a forklift hydraulic cylinder from a hydraulic cylinder manufacturer or distributor. One such company is Boom Cylinders. For more information, visit
