PMT CCC TYPE

PMT-316 CCC . PMT-625 CCC

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.

Les supports métalliques de base utilisés pour ces produits sont l’acier inoxydable AISI 316L et l’Inconel 625. Avec ce type de produit, il ne faut pas durcir thermiquement l’arbre It is not recommendable to use oil and grease with these bearings.
