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

Winter 2025 Update: Since December 2023 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at YORK XPS 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 Tyco Keystone 79U-003U-A000-A00 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 U.s.-Motors products, including obsoleted and phased-out U.s.-Motors parts and systems, as well as the all-new for 2023 U.s.-Motors 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 U.s.-Motors such as the D50P1DS spares. Related to this we have added to our service line-up the FF50E1DV manufactured by U.s.-Motors and we are pleased to be able to service most U.s.-Motors systems and parts. Due to increased demand we now feature H25P1GS by Manufacturer U.s.-Motors as well.

As a tip, you can find the entire U.s.-Motors products line-up in our inventory by simply searching for "U.s.-Motors" in the search box. Additionally we have now also available 7P1BC made by U.s.-Motors as well as the popular C30P2G original spares produced by U.s.-Motors

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.
