The invention relates to a pneumatic spring brake cylinder (4) for brake systems of vehicles, comprising a housing in which a spring brake piston (8) that is loaded by at least one accumulator spring (10) and is connected to a spring break piston tube (18) is guided in a movable manner and comprising an emergency release device (52) for the emergency release of the spring brake piston (8) in the event of a drop in pressure, said emergency release device containing a spindle (50) which can be rotated relative to the spring brake cylinder (4) and which can be screwed in a nut (56) that is held in a rotationally fixed manner in the spring brake piston tube (18) by means of a formfitting connection, said nut interacting with an axial stop (58) on the spring brake piston (8) in order to trigger a release movement of the spring brake piston (8) against the effect of the at least one accumulator spring (10). According to the invention, the formfitting connection is formed between an outer polygonal profiled section (60) which surrounds the outer circumference of the nut (56) in a circumferential direction and a complementary circumferential inner polygonal profiled section (62) on the inner circumference of an intermediate bushing (64) and between an outer polygonal profiled section (66) which surrounds the outer circumference of the intermediate bushing (64) in the circumferential direction and a complementary circumferential inner polygonal profiled section (68) on the inner circumference of the spring brake piston tube (18).
