Blowers / Fans

Fan support bearings require particular attention when devising a lubrication strategy. Because a broad range of bearing types can be employed it is important to understand the bearing and seal types before proceeding. This information is critical in order to understand the optimal grease delivery points, grease flow paths, the requirements for efficient grease exchange and the point(s) of grease exit from bearing housings.

During the implementation of perma STAR VARIO it is important to address the following items:

• Ensure that the bearing housing is correctly packed with grease in order to ensure efficient grease exchange. This is especially important for bearing types which must be re-lubricated from the side, rather than via a central re-lubrication groove.
• Where contact seals which are not free purging are in use, such as double lip seals, ensure that a suitable point for grease relief is introduced to the housing in order to avoid over-lubrication.
• Consider the use of high performance greases which can withstand the high rate of mechanical work which is applied by high speed rolling element bearings such as spherical roller bearings.

Mount a perma lubrication system at the lubrication point. Depending on the conditions prevailing at the lubrication point, the perma lubrication system can either be mounted directly or remotely.
