In modern automotive engineering, the use of high-performance materials is essential to meet the demands of efficiency, durability, and cost-effectiveness. Aiglidur® engineering plastic sliding bearings have emerged as a revolutionary solution in various automotive systems due to their unique properties. These bearings are designed to handle high loads, extreme temperatures, and harsh environments, making them ideal for critical components such as chassis, transmission, steering, and braking systems.
**Chassis Applications**
The chassis is one of the most crucial parts of a vehicle, directly affecting ride comfort and driving safety. Aiglidur® Z material is specifically engineered to perform under high pressure (up to 150 MPa) and temperatures reaching 250°C. Its low elastic modulus ensures excellent shock absorption, reducing vibrations and enhancing overall performance.
**Transmission Systems**
In the transmission system, Aiglidur® H4 bearings are increasingly replacing traditional metal sliding and rolling bearings. These plastic bearings offer superior wear resistance and can be used with cast aluminum substrates without causing surface damage. They are also resistant to engine oil and can operate at temperatures up to 200°C, making them a reliable choice for long-term use.
**Steering System**
For steering applications, Aiglidur® J bearings are preferred for their low friction coefficient and high hardness. These properties are especially important in the steering column assembly, where smooth operation and minimal friction are critical. The design allows for gap compensation, ensuring consistent dynamic and static friction levels, which improves steering response and control.
**Butterfly Valves**
In butterfly valves, Aiglidur® H4 bearings are often used due to their low friction and wear characteristics. These bearings can work effectively with shafts made of PA or PPS materials while maintaining a very low friction coefficient. Additionally, they support plastic spray processing, making them suitable for compact and space-efficient designs.
**Brake Components**
Brake systems require bearings that can withstand high temperatures, heavy loads, and corrosive conditions. Aiglidur® H2/H4 bearings are designed for these demanding environments. Their excellent resistance to wear and twisting ensures a remarkably long service life. This durability is achieved through the inclusion of fine particles and reinforcing fibers within the material structure.
**Cost-Effective and Efficient**
Beyond their mechanical advantages, Aiglidur® bearings are also more economical compared to traditional metal bearings. Their low cost, combined with excellent dry-running capabilities, makes them an attractive option for automotive manufacturers looking to reduce production costs without compromising performance.
**Conclusion**
The integration of Aiglidur® engineering plastic sliding bearings into automotive systems represents a significant advancement in materials technology. With their ability to perform under extreme conditions, reduce maintenance needs, and lower overall costs, these bearings are becoming a standard in modern vehicle design.
**Related Bearing Knowledge**
Choosing the right bearing material is crucial for optimal performance. Ceramic bearings, for example, combine the strength of needle roller bearings with advanced manufacturing techniques. When selecting bearing materials, it's important to consider factors like load capacity, temperature resistance, and compatibility with other components.

Single Lever Bath-Shower Mixer
1. Bathtub faucet: It is installed above the side of the bathtub and is used to open hot and cold mixed water. Those that can connect two hot and cold pipes are called duplex; The structure of opening and closing water flow includes spiral lifting type, metal ball valve type, ceramic valve core type, etc. At present, there are more ceramic valve spool single-handle bathtub faucets on the market. It uses a single handle to adjust the water temperature and is easy to use: the ceramic spool makes the faucet more durable and watertight. The valve body of the bathtub faucet is mostly made of brass, and the appearance is chrome plating, gold plating and various metal paint.
