The excavator swing hydraulic cylinder produced by Qingdao Micro Precision Machinery Co., Ltd. has 18 series sizes, with a standard working pressure of 21MPa and a maximum of 32MPa. Each series size has 4 rotation angles: 90 degrees, 180 degrees, 270 degrees, 360 degrees. Torque 500~5000N.m accepts customer customized torque. The maximum rotation angle is 1104 degrees. Double seal on drive shaft with double key or splined shaft (DIN 5482).

The cylinder body material of the excavator swing hydraulic cylinder is made of high-strength alloy steel pipe, which has high strength, corrosion resistance and wear resistance. These materials can withstand extreme temperature and humidity, microorganisms and chemical substances in harsh environments, ensuring that the swing cylinder will last for a long time. Stable operation.

The excavator swing hydraulic cylinder is a kind of hydraulic drive that converts the linear motion of the piston into the rotational motion of the shaft.

It has large bearing capacity, large driving torque, can rotate up to 360 degrees, has a compact structure and small size, and can be used in complex and harsh environments.

excavator swing hydraulic cylinders are widely used in: engineering machinery, mining equipment, agricultural machinery, special vehicles, and water conservancy equipment.

Main features of excavator swing hydraulic cylinder: internal spiral structure, small size and large output torque.

Advantages of the excavator swing hydraulic cylinder produced by Qingdao Micro Precision Machinery Co., Ltd.:

1. The key component of the swing cylinder is the spiral spline used to rotate and transmit torque. It has the characteristics of precise precision, uniform force, and smooth transmission. Furthermore, low-friction axial bearings and a unique sealing system layout are used. A multi-pronged approach enables the swing cylinder to have a lower friction coefficient during transmission.

2. Higher output torque:

We continue to innovate and verify the structural design. The compact design adopted by the swing cylinder can make full use of the existing internal space and generate sufficient torque under the action of fluid pressure. Therefore, compared with similar products, its output torque is increased by 10%-20% under the same specifications and dimensions.

3. Longer service life:

Each specification of the swing cylinder has been comprehensively analyzed and calculated by FEA engineers, and is continuously optimized to ensure that each specification of product can meet high standards of service life requirements. In addition, we are also equipped with two durability test benches dedicated to swing cylinders. Each product must pass in-factory verification to effectively ensure its durability performance and longer service life.

4. Flexible customer customization:

Extremely fast response time, accept any model and output torque and swing angle specified by customers.

5. All specifications of cylinders are designed by professional engineers

6. We use high-quality sealing kits purchased from American MPI, Japanese NOK and Swedish SKF.

7. All materials are processed by skilled workers and advanced CNC lathes

8. All hydraulic cylinders are 100% tested before leaving the factory to ensure that each cylinder meets the requirements

9. The hydraulic cylinder is packed in wooden boxes to ensure that the goods reach the customer safely

10. The product has a one-year warranty and provides lifelong tracking service to solve any problems you encounter during use.
