Duff-Norton offers the traditional style Type 1 & 3 journal end screws with and without keyed drive ends. These traditional styled journals coordinate well with the Duff-Norton End Blocks and can be delivered quickly. Additionally, Duff-Norton does have the machining capability to provide custom journal ends. Download "Journals and End Blocks" PDF above for more information.
Duff-Norton's End Blocks and Screw End Journals are the key to assembling a complete screw and nut system from the Drive End all the way through to Control End. Our End Blocks follow the conventional style, and together with a special journal design allow the user to integrate the following Duff-Norton components; Motor Flanges (Servo, IEC, NEMA frame motors), Gearmotors (brake, non-brake, IEC, NEMA gearmotors closely coupled with Duff-Norton Motor Flanges), Ring Kit Encoders (coupled between Duff-Norton motor flanges and motors or gear motors Limit Switches and Potentiometers, Control panels - custom designed for each application.)
How does this work? Simply remove the bolts from the End Block's face plate, and use the longer bolts provided in the Duff-Norton kit for that drive or control component for mounting that component to the block face. All mounting holes and surfaces have been designed for proper fit. Duff-Norton specialty screw end journals have also been specifically designed to properly mate with each of these control and drive components.
