MAINTENANCE
BRO-MAS® is a maintenance-heavy bushing, oil or grease lubrication is necessary. SBS designs lubrication grooves to reduce maintenance to a minimum.
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
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.
