Product catalog summary

Introduction
The document introduces the OneWay bearing clutch system developed by MPS Micro Precision Systems AG, highlighting its innovative features and applications in the watchmaking industry.

Specifications

Miniaturization of the freewheel system.
Very low unlock torque.
Backlash angle below 7°.
Lubrication-free system using ceramic balls.

System Description
The OneWay system is a radial ball clutch that operates with a plate gripping mechanism. The ball separator, or cage, is segmented, allowing the balls to jam between the outer ring and cage segments, functioning as brake pads against the inner ring.

Applications and Advantages
The OneWay bearing is utilized in self-winding systems, acting as a reverser. It combines two unidirectional bearings with an oscillating mass bearing, enabling a bi-directional self-winding system in a compact space. This high-performance system is favored by leading watch manufacturers.

Patent Information
The OneWay system is protected under European patent no. EP1134626A1, marking it as an exclusive MPS product.

Innovations
MPS has miniaturized the unidirectional bearing concept, offering new possibilities for timekeeping design. The system includes a three raceways bearing with an integrated freewheel system on the lower stages, supporting both declutching and clutching modes of operation.
