STANYL® PA46: A Reliable Choice for High-Speed Motors in New Energy Vehicles

Electric vehicle motors are generally more powerful than traditional internal combustion engines, with operating torque and speed far exceeding those of fuel engines. To achieve more compact and lightweight electric motor units, it is often necessary to further increase the motor speed to compensate for the loss of torque and power output caused by lightweight and compact designs. This undoubtedly places additional speed demands on the bearings used in these high power density motor units. The bearing cages in motor bearings must withstand high centrifugal forces and high operating temperatures. To ensure the reliable operation of the bearings, the cage materials are usually required to have excellent high-temperature mechanical properties and friction performance. Stanyl^®PA46 exhibits superior mechanical and frictional properties compared to its counterparts in high-temperature environments commonly found in high-speed bearing applications.

Compared with other high-performance polymers used for high-speed bearing cages, such as PEEK, Stanyl^®PA46 can usually meet the performance requirements of cages at significantly lower cost.

Stanyl^®PA46 provides high-performance solutions that help automotive bearing manufacturers address various application challenges in a cost-effective manner. This high-temperature thermoplastic material possesses:

Extensive testing and rigorous practical applications have confirmed that Stanyl^®The performance of PA46 often surpasses that of PA66 and many other engineering plastics. Its core advantages include:

Significantly reduce component deformation.At a speed of up to 30,000 revolutions per minute, Stanyl^®The deformation of bearings cages made of PA46 is reduced by 21% compared to PA66.

Excellent heat resistance and chemical aging resistance.Stanyl^®PA46 has undergone rigorous testing, demonstrating stable performance in high-temperature environments and effectively resisting chemical corrosion from commonly used automotive oils and greases, ensuring reliable and long-lasting performance in demanding automotive bearing applications.
