GG keyless locking bushes connect the shaft to the hub without a keyway. The GG type has one of the most complete dimension ranges, which also includes less common intermediate sizes and bushes for large shafts.
GG keyless locking bushes - a wide range for non-standard shafts
The extensive range makes it easier to choose a bush for a non-standard shaft or an existing hub, without modifications. Before clamping, the bush slides freely on the shaft, so you can position the pulley precisely angularly and axially - this makes it easier to synchronise several pulleys on one shaft.
