Winter 2024 & 2025 Q1 Developments in Industrial Automation - expanded product offering and diagnostic and repair services at YORK

Winter 2025 Update: Since December 2022 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at YORK have been able to ramp up our service response times with expedited shipment schedules back to normal, providing replacement parts and services following normal response times. Our departments are now working on near-normal production levels and our delivery and service schedules back to regular operation levels. In addition to the Duff-norton 50110 28WW 5110 parts and service support, we have been able to add new lines of product and service:

Expanded Service and Repair Support for New Product Lines: We offer full support for discontinued Siemens products, including obsoleted and phased-out Dunkenmotoren parts and systems, as well as the all-new for 2025 Dynamics-Research product line-up. Starting Q1 2025 YORK is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader Siemens such as the CPU317F2PNDP3172FK130AB0 spares. Related to this we have added to our service line-up the GR80X80 manufactured by Dunkenmotoren and we are pleased to be able to service most Dunkenmotoren systems and parts.
