Woodruff key DIN 6888 6x10 Stainless steel
r1 chamfering (all sides), bevelled or rounding of manufacturer's choice
r2 rounding of groove bottom for shaft and hub
1 For connection dimensions, in particular of shaft ends, the allocation of the woodruff key cross-sections to the shaft nominal diameters must be maintained. Allocation I applies wherever the woodruff keys are used like parallel keys, i.e. to transmit the entire torque. Allocation II applies wherever the woodruff key is used only for fixing the position of the drive element and for transmitting the torque of other elements, e.g. cotter or taper.
2 The permissible differences for the groove widths apply only as a guideline. It is recommended to comply with ISO grade IT8 instead of IT9 for the widths of reamed grooves (i.e. P8 instead of P9. N8 instead of N9 and JS8 instead of JS9).
3 In the production drawings, the dimensions t1 and (d1 - t1) plus t2 and (d1 + t2) can be entered adjacently to one another, however in many cases the dimensions t1 and (d1 + t2) are sufficient. It may be necessary here to take into account the permissible differences and machining allowances of shaft and hub bore.
* Use row A (high hub groove) for preference, conforms to DIN 6885-1 (t2 with back clearance).
** Row B (low hub groove) for machine tools, conforms to DIN 6885-2.
*** With allocation II of the woodruff keys to the shaft diameters the tolerance field D10 can also be selected.
**** similar to DIN 6888
