Yes.  However, standard OHLA units are configured for a horizontal mounting (shaft parallel with the ground).  Applications requiring a vertical shaft mounting orientation, or that are mounted at an angle or incline, will require special features to retain lubricant in the uppermost bearing and may require additional modifications as well.  These features vary depending on the model of the OHLA and the application’s operating parameters.  Please contact factory for details if you have a vertical or inclined mounting orientation.
