BASE TYPE
ZX-750V5T
High speed and heat are his speciality
ZX-750V5T - is a thermoplastic material with antifriction characteristics based on polyimide (PI).
The latest development in the field of materials for high speeds and high temperatures. Particularly suitable for sliding speeds beyond 200 m/min and temperatures exceeding 300 °C.
Plain bearings slideways made of polymers ZX-750 should be applied if the use temperature exceeds +100°C, and the durability and dimensional stability need some improvement.
