For design F-One, Fersa has as bearing designations series F-16000 for ball bearings and series F-15000 for tapered roller bearings. F-One units are double-row angular contact ball bearings (F16000) and double-row tapered roller bearings (F15000) with two inner rings and one extended outer ring.

F-One bearing units have a defined and pre-set bearing clearance, lubrication for life and mounted sealing system. Double row angular contact ball bearings have a high moment for load capacity, meant to support the forces during cornering. F-One tapered roller bearing has a high load capacity through a space-saving construction

The axial clearance is pre-set and takes into consideration the adjustment during assembly in order to reach the optimum preload after mounting. Additionally, the mounting seals eliminate the necessity for automotive manufacturers to use extra seals during operation
