Abstract: An arrangement for force-free retention of a bearing system having an axis of rotation comprises a cylindrical hollow axle for concentrically receiving and holding the bearing system. By way of a hold-down and release mechanism, a bearing shell can be fastened to the hollow axle in such a manner that, when the bearing system is not acted upon by a load, all lateral and axial forces applied to the arrangement can be transmitted via the cylindrical hollow axle into axle receiving devices.

Abstract: Bearing arrangement for a shaft rotatable around an axis of rotation comprising a bearing including an inner bearing part for coupling to an end of the shaft and an outer bearing part for coupling to a mounting structure, and a retaining and pivoting element, which is connectable to the inner bearing part or the outer bearing part, wherein the retaining and pivoting element is designed for securing the end of the shaft against movement in a direction in parallel with the axis of rotation (4) in relation to the bearing and for permitting the end of the shaft to be pivoted with respect to the axis of rotation, and an arrangement comprising the bearing arrangement and the shaft, as well as an oscillator comprising said arrangement.

Abstract: Improved serviceability of cold metal cutting machines is accomplished in a modified gearbox structure enabling several annular components that are conventionally attached by press-fit to be attached instead by slide-fit for easy removal and replacement, eliminating hammering and/or heating required conventionally to release press-fit components. Press-fitting of a motor shaft coupling is eliminated by introduction of clamping slide-fit structure. Press-fits of two thrust bearings to the housing are eliminated by introduction of slide-fit adaptors. Instead of the conventional practice of making the saw rotor integral with the low speed shaft, a separate saw rotor bolted to the shaft enables easy replacement of the oil seal.

Abstract: Roller bearing for a roller in a printing unit of a printing machine having a receptacle for a tang formed on an end of a roller, and a hold-down device movable for respectively locking and releasing the tang on the end of the roller, includes a device for fastening, with spring loading, the receptacle and the hold-down device radially to one another with the roller tang formlockingly received therebetween, the fastening device having a longitudinal axis, and the hold-down device being swivelable, with a force overcoming the spring loading, about the longitudinal axis of the fastening device and away from the roller tang.

Abstract: A quick-opening bearing block containing a set of bearings to support a rotating shaft comprising a block base, mountable to a supporting surface, containing the lower bearing, a cover hinged to the base, containing the upper bearing, where the hinge is spaced apart from the bearings, and a T-shaped fastener mounted on the base between the bearings and the hinge, adapted to pass through a slot formed in the cover, to permit the cover to be opened and closed quickly, and thereafter locked down in closed position on top of the base to support the shaft in the bearings by simply twisting the fastener out of alignment with the slot.
