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 SK-9005-1X 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 Durant products, including obsoleted and phased-out Honeywell parts and systems, as well as the all-new for 2025 Dukane 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 Durant such as the Model5D11R spares. Related to this we have added to our service line-up the DISOE51402625175 manufactured by Honeywell and we are pleased to be able to service most Honeywell systems and parts. Due to increased demand we now feature MCS250A609RevH by Manufacturer Dukane as well.

York Scientific's New & Featured Automation Replacement Parts: Starting early January 2025 York has Dynapar Brand 62502566341 in stock, original and quality replacement parts available for immediate dispatch to meet your requirement for spare replacements. Spare units by Siemens such as W77441PRO6GK57441AA602AB0 equipment made by Siemens have been added to our featured items. As a tip, you can find the entire Siemens products line-up in our inventory by simply searching for "Siemens" in the search box. Additionally we have now also available 51305072100 made by Honeywell as well as the popular 20HB1201ES1 original spares produced by Dukane

Servo Motors, Spindles, and Electric Motors Rewinding and Rebuilding. We have expanded capacity at our service centers to do complete overhauls of industrial electric motors and spindles. Refurbishment processes are held to stringent QA standards to adhere to or exceed manufacturer's specifications. Overhauls include motor bearing replacement, stator rewinding, and rebalancing. Additional overhaul and rebuilding capabilities of products such as the SB957500P by Dynamic and W77441PRO6GK57441AA602AB0 spares by Siemens are also now also our York Scientific's line-up of service offerings. This also includes the original EcoHTE03240006E03240006 Spares made by industrial controls and automation manufacturer Durr.
