Cina Bushing silinder Produsen, Pemasok, Pabrik

The bushing on the hydraulic cylinder is a key mechanical component, which is mainly used to reduce the friction between the inner wall of the hydraulic cylinder and the piston rod, and also plays the role of sealing, supporting and guiding.

Why use a bushing instead of a bearing?

The use of bushings instead of bearings in hydraulic cylinders is mainly based on comprehensive considerations of the hydraulic cylinder's working characteristics, cost-effectiveness, and maintenance requirements. The following is an analysis by Qingdao Micro Precision Machinery Co., Ltd.:

(1) Working characteristics of hydraulic cylinders

Hydraulic cylinders are usually used in low-speed, high-load linear motion scenarios, and the relative movement speed between the internal piston rod and the cylinder barrel is low. Under such working conditions, the sliding friction characteristics of the bushing are more suitable for the operation requirements of the hydraulic cylinder, while the rolling friction characteristics of the bearing may cause unnecessary complexity and cost due to high-speed rotation.

(2) Cost and maintenance

The bushing has a simple structure, is easy to install and replace, and has a relatively low cost. In contrast, bearings usually require more precise installation and alignment, and have higher maintenance costs. The working environment of hydraulic cylinders is usually harsh, and the self-lubricating characteristics of the bushing enable it to operate stably without relying on external lubrication, reducing maintenance requirements.

(3) Sealing and wear resistance

Hydraulic cylinder bushings are usually made of wear-resistant and self-lubricating materials, which can not only reduce friction, but also effectively prevent hydraulic oil leakage and ensure sealing performance. In addition, the material properties of the bushing enable it to perform well in high temperature, high pressure and corrosive environments.
