These characteristics have to be somehow controlled to make everything working properly. Shaft keyseat dimensions and tolerances were given in ISO R I Googled “Standard Metric Keys” and the first hit I got told me that for a 75mm diameter shaft the “standard key size” is 22mm wide x 14mm high.
The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits isl metric bores and keyways.

SCOPE This standard presents metric dimensions, tolerances, sizes and fits for straight bores, tapered bores, keys and keyways for unmounted industrial flexible couplings. To fully and unambiguously define a rectilinear key you need: Download Now White Paper: Bores are to be measured prior to cutting the keyway.
Hardened keys shall be alloy steel through hardened f773 a Vickers hardness of to HV.
Red Flag This Post Please let us know here why this post is inappropriate. In terms of dimensioning and tolerancing of keys and keyways the standards focus solely on aspect of size of features, without paying any attention to other important geometric characteristics, like orientation and location of a keyway relative to axis of shaft and housing.

is One of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the same. I don’t have either standard. Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: When other materials and properties are required, these shall be as agreed upon by the supplier and customer.
Inspection methods for straight and tapered bores and keyways are included in the annexes.
Suggestions for improvement of this standard will be welcome. I figure that a clerical level person should able to take your parts list and order the parts on it such that you can assemble r77 system and it will work. It is not clear from your second post what may be included in the “certain companies number”.
