Some Key Uses of Kawasaki SX Hydraulic Motors!

Today, hydraulic motors in most industries play a secondary role. It’s pushed aside by electric motors. But the advantages of Kawasaki SX hydraulic motors clearly manifested in certain situations, provide a stable demand for hydraulic motors. For example, it’s advisable to buy a hydraulic motor if there is limited space or difficult access to the installation site. However, while choosing one, the dimensions of the hydraulic motor are three times less, and the weight is almost 15 times less than that of electric motors of the same power.

Hydraulic motors have a wider range for adjusting the speed. It’s also essential that the time required for starting and accelerating to the specified operating parameters for a hydraulic motor is only a few fractions of a second, in contrast to high-power electric units.

The movement of the shaft in the Kawasaki SX hydraulic motor is easily adjusted depending on the need using the means designed to regulate the hydraulic drive. For optimal control of the movement of the motor shaft, it’s recommended to select and buy a hydraulic valve of the same brand as the engine itself.

In the following, we discuss in detail the various uses of Kawasaki SX hydraulic motors.

Let’s have a look!

What is a Hydraulic Motor?

A hydraulic motor is a device that converts the energy of a fluid into mechanical energy that drives the working body of the machine. A working body is a shaft, which receives the converted energy, due to which the rotation of this shaft is carried out, which drives the machine.

Compared to electric motors, hydraulic motors have a number of advantages. They are more compact and lighter in weight while providing sufficient power. Another important advantage of hydraulic motors is their high efficiency and high starting speed. In addition, hydraulic motors are devices that are resistant to frequent starts and stops.

Application Area of ​​Hydraulic Motors

In various fields of activity, a wide variety of types of hydraulic motors are used. Each of which differs in its design and energy transmission mechanism. For certain types of machines, one or another type of engine is selected that meets the tasks and is optimal for their solution.

Hydraulic motors are used when it’s necessary to obtain high speeds of rotation of the shaft or low speeds of rotation in conditions of a large generated torque. An example of the latter would be the turning of the tower of a row of truck cranes. Kawasaki SX hydraulic motors are widely used in machine tool drives. 

Hydraulic motors are often used in relatively simple hydraulic systems that don’t have high requirements for shaft rotation uniformity. Quite often, hydraulic motors can be used in shunting and narrow-gauge diesel locomotives, providing the process of transferring energy from the engine to the wheels. Also, hydraulic motors are used in household water meters. Such hydraulic motors are small in size and power.

Benefits of Hydraulic Motors

Despite the fact that Kawasaki SX Hydraulic motors are still less common than electric motors, these are much more efficient and more successful than the latter. In comparison, hydraulic motors are much smaller in volume and weight, while they have a much wider range of speed control. They start and accelerate quickly enough, and all other technical characteristics of hydraulic motors are far ahead in comparison with the characteristics of electric motors. Especially in demand today are Kawasaki SX hydraulic motors designed to drive working units in a wide variety of hydraulic systems of agricultural, municipal, road, machines.

Another undoubted advantage of hydraulic motors is that they aren’t afraid of frequent stops, on-off procedures, frequent readjustment of travel and reverse. In this regard, the hydraulic motor is just as reliable, stable in operation and durable as a gear pump. They require standard routine preventive examinations for their full-fledged operation under “jerking” loads.

All the advantages of hydraulic motors today are often overridden by their shortcomings, which force constant control. It includes the viscosity of the working fluid, its leaks through gaps and seals at high pressure in the system, as well as its temperature and purity.

When choosing the type of motor, the main criteria should be a comparison of the pros and cons in their operation under specific operating conditions. For example, if a frequent shutdown of the unit or readjustment of its stroke is envisaged, the hydraulic motor will certainly be optimal.

There are various companies that produce a huge range of pneumatic and hydraulic equipment, including hydraulic motors. You can buy such products at a relatively inexpensive price in view of the price of a direct manufacturer. 

Such companies have their own research laboratory, which makes it possible to create unique product samples that sometimes have no analogues in terms of the breadth of application and functionality, as well as in terms of performance. And the undoubted advantage will be the availability of always the required amount of products from the company’s catalogue in the warehouse.

What Are the Features Of Hydraulic Motors

Axial Piston

The key element of the hydraulic unit is the crank mechanism where the cylinders move parallel to each other, and the pistons move with them. The design may include an internal reverse mechanism, so the unit is mounted at an angle of no more than 30 degrees. The advantages of this type of motors are in demand in the production of high-precision machine tools, aircraft construction, as well as for the assembly of bulldozers and excavators.


Gear motors are the cheapest segment. Functionally, such a motor is designed for reverse fluid flow. When it arrives, the gears are activated and torque is generated on the shaft. For long-term operation, the unit must operate at low speeds. Gear models have low efficiency, which in many cases is compensated by the ease of operation, unpretentious maintenance and the absence of strict requirements for the quality of the working fluid.

Radial Piston

Displacement motors are called radial piston motors where the cylinder block is installed perpendicular to the executive bodies. It forms an angle of 45 degrees with them. If the angle is less than the specified value, it belongs to the category of axial models. Radial piston models are divided into two types:

Radial-plunger assemblies create a large moment of force. Therefore they’re actively used in ports and on ships to rotate structures. In addition, they’re installed in mining and agricultural machinery.

Wrapping Up!

Whether it’s Kawasaki sb hydraulic motors or others, it’s important to choose a unit that is suitable for special equipment in size and performance. Today, it’s not particularly difficult to purchase a hydraulic motor of one type or another. However, when buying, you need to understand for which application you need the device, as well as know the basic parameters required to solve specific problems. At the same time, a variety of models, their design features and technical characteristics allow you to choose the right type of hydraulic motor for a specific field of application.

For selection or repair of a hydraulic motor, choose a reliable company. The professionals of such companies will identify compatible equipment models and help you buy them at a bargain price or repair them. In addition, they’re engaged in the maintenance and repair of hydraulic devices on a modern base equipped with everything necessary for diagnosing and eliminating breakdowns.
