Oilless Bush Material Technical Data
* For higher requirement Oilless Bush Materia -e.g. higher temperature ranges – different materials are available in this category. Oilless Bearing | Oilless Brass Flange Bushing Graphite Plugged Bearing.
It is a maintenance-free oilless bearing material, but an initial greasing is mandatory for the “running-in”process. A lithium aging-resistant grease should be used.
