Automatic transmission is one of the most important yet complicated mechanical components within the automobile system. Automatic transmission is consisted of mechanical, hydraulic, electrical, and computer system all working side by side to produce driving forces to the vehicles.

WINTEK’s AC compressor seals are composed of metal cases with adhesion of rubber sealing primary lip (HNBR) and assembled with a high performance PTFE lip.

Since R-12 refrigerant is environmentally harmful and is now substituted by R-134a hydro fluorocarbon HFC refrigerant which it requires to operate in specific lubrication and higher temperature. Our AC compressor seals with HNBR rubber material designs are compatible with R-134a refrigerant in high temperature and new lubricant environment.

WINTEK undergoes testing process to stimulate the AC compressor seals while operating within the system to make sure that we provide customers with higher and excellent functionality, performance and long lasting seals. Wide ranges of AC compressor seals types are also available in WINTEK.

Power steering system helps drivers steer wheels while operating vehicles by adding energy to the steering mechanism. Energy added to the system by power steering helps drivers to reduce physical strength needed when turning the wheel whether when the vehicle is moving at high speed, low speed, or static.

Types of adding power to the steering system are hydraulic power steering system, electronic power steering system, and electro-hydraulic power steering system (Hybrid). Hydraulic power steering system uses pressurized hydraulic fluids to generate power to the machinery whereas electronic power steering system generates power to the machine by using electric motor. Electro-hydraulic power steering system utilizes the same hydraulic technology but only the hydraulic pressure is generated by a pump driven by an electric motor.

The use of power steering seals is to prevent leakage and retain hydraulic fluids within the system and provide low friction. Mainly, design of power steering seals are for application of reciprocating rack shaft and rotary steering shaft in an automobile steering system. Power steering seals with inserted backup ring have high endurance of pressure to prevent deformation of the seals caused by the pressure.

Within the business operation, logistics management plays an important role in increasing efficiency and effectiveness of the flow whether it is based on physical goods or abstract items such as information. In our case, we discuss transportation of physical goods that include raw materials, equipment, finished goods, and other related items. The use of trucking not only appears on regular pathways of the road, it is also commonly use in various places such as construction site and mining field.

One of the major transportation of choice, truck, has been widely used to transport items from point to point in the business operation. The environmental condition may be demanding and truckers may face extreme weather or road condition when transporting goods.

Thus, the design of hub seals are to focus on maintaining truck’s operating ability when facing extreme weather and road condition. Hub seals help isolating outside dirt or any other mediums from entering into the wheel hub causing damages to the system. Hub seal’s multiple layers and lips design provides effective sealing solution to wheel hubs and ensures the driver’s safety while transporting items.

The metal scraper contains scraper lips of two different materials. One is a thin metallic lip whereas the other one is a rubber lip. The metal scraper lip removes firmly adhering dirts and ice particles. The secondary lip of elastomer material enhances the overall scraping function, such us fine sand grains, water and similar foreign matter are reliably scraped off. Both scraper lips have a smaller diameter than the nominal diameter of the piston rod, thus ensuring a tight fit of the scraper lips. The metallic lip is guided flexibly in radial direction and can easily follow any possible deflections of the piston rod.
