The advantages of the mps OneWay bearing:
Miniaturisation of the freewheel system for compact design;
Very small space set aside for self-winding system;
Optimized cage segment design (brake pads) for the minimum backdash (dead angle);
The various interfaces of the couplings are calculated to enable the system to tolerate high loads;
The operating clearance is totally controlled and tested to 100% to minimize axial play;
Lubrication free system using myrox ceramic balls developed by mps

OneWay-the new ball bearing radial clutch generation
The mps OneWay system is a radial ball clutch class product. The coupling is of the plate gripping type. The cage (also called the ball separator) is divided into several segments. The coupling between the respectively inner and outer rings inside the bearing is in one direction when the balls are stopped by jamming between the outer ring and the segments of the cage used as brake pads against the cone (inner ring).
mps's great complication
The unidirectional OneWay bearing is used in the self-winding system and acts as a reverser too. mps has succeeded in coupling together two unidirectional bearings to the oscillating mass bearing. A major advantage of this device is that the bi-directional self-winding system is concentrated into a very small space. Its high level performance has led to its adoption by many of the leading watch-making manufacturers.
OneWay-an exclusive product developed by mps
The OneWay is covered by the CH 694 025 A5 patent. It is produced by mps under exclusive license.
