Special Ball Bearings
GRW not only develops and produces standard and high-precision ball bearings but also all required variants of miniature ball bearings.
Double-row deep groove radial bearing or angular contact ball bearing with divided inner or outer ring are called Superduplex bearings.
The raceways are on the one-piece ring. This reliably prevents any radial displacement during installation and ensures optimum running characteristics.
The divided rings (inner or outer rings) are paired in accordance with customer's wishes. This ensures that GRW bearings have the desired axial preload.
