 Machined
Parts
Key
Machined keys are used in slots milled into shafts to
provide a means of attachment and transmit power to
a hub. Keystock is divided into two categories. One
has a plus tolerance over the nominal width and is designed
to have an interference fit with the mating key slot.
The other is minus tolerance barstock which would have
a looser fit in the same key slot, but provide easier
assembly and disassembly.
In
corrosion resistant materials minus tolerance barstock
in 303 Stainless and 316 Stainless are generally the
only on the shelf options. Nickel Systems' shop can
provide finished keys in these materials as well as
Alloy C276 (Hastelloy C®), Alloy 20 (Carpenter 20®),
Alloy 400 (Monel®), and other Nickel-based alloys.
