PMT STE TYPE
PMT-316 STE . PMT-625 STE
This product identifies a new generation of Sliding Bearings for applications in low and high temperature, thanks to a special coating performed with a system similar to the PVD process. This coating confers to the material an excellent resistance to extreme temperatures while maintaining a good coefficient of static friction even with a dynamic heavy load.
Die hierfür verwendeten metallischen Trägerschichten Produkt sind Aisi 316L und Inconel 625. Mit diesem Art des Produkts, sollte die Welle nicht wärmebehandelt eingereicht werden. It is not recommendable to use oil and grease with these bearings.
