PROPERTIES
TEF-MET® is a maintenance-free material due to the PTFE sliding layer. Outstanding sliding and wear performance. High load capacity and very versatile bushing. Extended performance due to the bronze backing.
RANGE OF APPLICATION
hydraulic cylinders, cranes and construction machinery, all sorts of production machinery, pumps and medial devices
MAINTENANCE
TEF-MET®/B is maintenance-free with a PTFE sliding layer. It is not necessary to lubricate this material, but basically possible!*
MOUNTING ADVISE
Housing: Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment Shaft: Chamfer 5 mm x 15°, for easy insertion of the shaft
Gluing: Adhesive should not contact the sliding surface!
CAPTION
Special dimensions and imperial sizes are available on request
* 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.
