Material: Aluminium, polished. Coupling attachment assembled. Can only be supplied with revolving, cylindrical handle made from plastic with threaded steel bolt and with hub keyway. According to safety regulations, handwheels must be mounted on the shaft in such a way that they do not rotate along with the machine drive. Safety handwheels comply with this regulation. Procedure: Wheel disengaged if not used. By axial displacement of the wheel (pulling) the two serrated wheel rims are engaged. The wheel is now positively keyed to the shaft. When the wheel is released, it automatically disengages. The coupling elements are assembled together in an enclosed unit. Coupling attachment made from steel, nitrided, bearing surface ground and PTFE coated, for minimal friction between bearing surfaces and high wear resistance. An oil hole is provided, which serves to connected to a pressure oiler in the wheel hub. Frequent lubrication is an important precondition in guaranteeing the correct functioning of the plain-bearing coupling attachment. The range of application of these handwheels is limited to low shaft speeds, or to higher speeds of only short duration (e.g. feed screws for milling machine table with rapid feed). The coupling attachments can also be supplied separately, to be mounted with existing handwheels. Prices on request. We assume no liability for any consequential damage.
