Retaining rings for shafts

DIN 6799 are radial retaining rings for shafts, which offer wide application possibilities.
They can be assembled by simply pushing them into the slot on the shaft, using the appropriate Assembly Plier.

For an easier and faster mounting by the use of Dispensers and Assembly Pliers, retaining rings type DIN 6799 can be supplied stacked on steel rods.
