Stober has been cutting helical gear since the 1940s.

​Stober uses wide gearing with real helical toothing to achieve higher load capacity of root stress, pitting and has higher load rating of planetary bearing. This results in higher durability compared to their competitors.

Without preload at output, there is less heat generated during motion, resulting in higher lifetime and less leakage risk.

​Stober gearheads use cylinder roller bearings at output. This reduces rotational friction and support radial and axial loads. Compared to ball bearings, roller bearings can support heavy radial loads. They can operate at moderate to high speeds.

The selection of synthetic oil VG150 as part of the careful selection process during the design phase.


Stober's gearheads have been the gearheads of choice on Applied Materials CMP machines since 2003 when Reflexion LK systems were shipped. Subsequently, Stober's gearheads are also selected for legacy Applied Materials CMP Mirra and Reflexion systems.
​Alpha Engineering Solutions Pte. Ltd., in partnership with Stober, is the exclusive distributor of Stober's gearheads used on Applied Materials CMP systems.
