An innovative way of mounting the oscillating weight on the bearing


Oscrew

The Oscrew product is a new system for attaching oscillating weights to bearings. It is intended for rotors with a clean design, allows the oscillating weight to be removable and doesn't require additional components. The Oscrew oscillating weight has a threaded center diameter that allows it to be screwed directly onto the outer ring of the bearing.

The Oscrew system offers a clean aesthetic similar to that of the crimped rotors. It is removable and requires no additional components. The best of all current solutions is thus concentrated in the innovative Oscrew system for which a patent has been filed by MPS.

Laboratory tests have proven the reliability of this solution. Rotors were subjected to vibrations, repeated shocks and shocks of 5'000 g. The use of the Oscrew system is thus possible for all types of products, including sports watches exposed to the most difficult conditions.

Benefits

  • Pure aesthetics compatible with Haute Horlogerie
  • Removable, allowing the replacement of one of the two rotor components if necessary
  • Optimized supply chain with no additional components
  • Compatible with the MPS Flyfix nut, allowing one bearing reference to be assembled with both types of oscillating masses

An innovative mounting system

In recent movements, the rotation of the oscillating weight is generally ensured by a ball bearing, the whole forming the rotor of the automatic watch. There are several methods of fixing the bearing on the oscillating weight:

  • Crimping offers a nice, high-end look but is not removable if one of the two rotor components is replaced.
  • The locking blades offer interchangeability but unfortunately have a look that is not compatible with the most high-end timepieces.
  • The MPS Flyfix system, with its additional nut, is an aesthetic, removable and reliable solution, provided that the necessary volume is available for its integration.

In terms of aesthetics, Oscrew is similar to the crimped rotors. However, its innovative mounting system is far superior to crimping. Coupled with a clean appearance and the advantage of being removable, Oscrew therefore combines all the advantages of other solutions in a single system.


A team listening to your concerns

베어링에 웨이트를 조립하면 일부 고객에게 심각한 스크랩이 발생할 수 있음을 확인했습니다. 미세 조립 전문가인 당사 엔지니어의 반응은 압입 및 리벳팅이 베어링 작동에 미치는 영향을 예측하는 동시에 사용되는 다양한 재료를 고려하는 모델과 공정을 개발하는 것이었습니다. 따라서 MPS Watch는 작동으로 인한 스크랩을 생성하지 않고 안정적이고 반복 가능한 조립 프로세스를 보장할 수 있습니다. 마지막으로 최적화된 물류 관리는 응답성과 유연성을 제공합니다.
