recieved a drawing today.
and there's some markings i don't recognize.
note：it's a shaft drawing.
here's the following marks i don't recognize.
this is a pic i found similar to the one i recieved
in mine FR is swapped with FG.
Ra 0.35 rcc/FG and Ra 0.20 ga/FG
what does rcc and FG stand for?and ga? i know Ra mean roughness extent.
any help would be appreciated.
and thanks in advance

Ra - Rotational Angle
Fg = Weight of load
Ga -Gravitational angle
Can't remember what the RCC was for?
