Abstract

A rotational control apparatus is shown in its most preferred form as a clutch-brake including an improved housing having a cylindrical body portion and first and second circular shaped ends removably secured thereto. The body portion includes an axially extending annular member intersecting with a radially extending annular member. The radially extending annular member forms an interface surface and a surface for reciprocal receipt of a piston inside the axially extending annular member and forms a mounting flange outside the axially extending annular member for securing axially extending studs threadably received in the second housing end. The first housing end includes an axially extending projection having surfaces for receipt in the axially extending annular member and for reciprocal receipt of the piston. The first housing end includes first and second L-shaped, oppositely directed bushings having their first legs rotatably received but axially fixed on the output shaft and having their second legs capturing an annular shoulder formed in a circular opening of the first housing end.
