Tell [us the types of motors you are using,the approximate weight of your equipment,the average life you are receiving from yourpresent gearing, and let us make some sugges-tions toward increased life and lower cost formotor gearing. Ball bearing trolleysfor long life and minimumwear on wheels and overhead The sensitive action of the Nuttall ballbearing trolley bases will show sav-ings which at first may not be appar-ent to you. The alleviation of all friction andbinding at the base swivel allows thetrolley wheel to easily follow the slight-est curvatures in the trolley wire. The base swivels equally well with the pole at any angle between vertical and horizontal. The ball bearing base not only lasts longer than an ordinary base, but also increasesthe life of trolley wheels and overhead construction.
