PROPERTIES
Corrosion-free and maintenance-free material due to stainless steel and PTFE. Outstanding sliding and wear performance. NOX-MET is chemical resistant towards alkaline and acidic medias!
RANGE OF APPLICATION
Chemical and pharmaceutical industry, medical engineering, food industry, fittings
MAINTENANCE
NOX-MET® is maintenance-free bearing material with a PTFE sliding layer, therefore lubrication is not necessary but possible.
MOUNTING ADVISE
Housing: Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment
SBS advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.
CAPTION
* For higher requirements – e.g. higher temperature ranges – different materials are available in this category.
** The listed values in the material properties are valid for optimal operating conditions. By changing the conditions of application, e.g. an increase in the sliding speed or strain, these values could shift.
Special dimensions and imperial sizes are available on request
