Abstract: An in-transit mixing machine drive (2) having an output bearing (8) for supporting an output shaft for rotation relative to a drive housing, in which the output shaft is arranged inclined relative to a horizontal plane (5) at an angle (?) and the output bearing (8) is formed by a pendulum roller bearing (9) whose rolling bodies (13, 14) roll in two bearing rows (10, 11) at pressure angles (?, ?) about a bearing axis (12). The pressure angles (?, ?) of the two bearing rows (10, 11) differ from each other or the rolling bodies (13, 14) of the two bearing rows (10, 11) differ from each other.

Abstract: A multiple-row radial bearing with at least one bearing race and pertaining rolling bodies, with the bearing race having at least one central collar, is characterized in that the central collar of the bearing race is formed by a single-piece ring (11), which is provided with a slot (12) and has variable diameter, for insertion in a circumferential groove (10).

Abstract: The invention concerns a radial rolling bearing having cylindrical rolling elements which roll between an inner and an outer ring while individual spacers are disposed between every two adjacent rolling elements, the spacers comprising, on both sides of their central longitudinal plane, contact surfaces while being guided during rotation of the radial rolling bearing by one of their end sections on a raceway of the inner or the outer ring.

Abstract: A double-acting rotary drive for a control device having an end position fixed in the form of a stop, includes a motor, a torque-changing gear connected to the motor, a driver associated with the torque-changing gear for neutralizing a torque-increasing action of the torque-changing gear or switching on a torque-lowering action after the torque-changing gear rotates through a portion of a total given rotational path thereof, a return travel lock for locking the torque-changing gear in place being released before the driver becomes operative.
