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 Union Semiconductor UM851 UM851A 11-95070617 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 Carrier products, including obsoleted and phased-out Unitrol-Electronics parts and systems, as well as the all-new for 2025 Universal 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 Carrier such as the HK05ZG002 spares. Related to this we have added to our service line-up the 9280B3 manufactured by Unitrol-Electronics and we are pleased to be able to service most Unitrol-Electronics systems and parts. Due to increased demand we now feature SHCSB1GM415009A2WR by Manufacturer Universal as well.

Additionally we have now also available EM100100816245000 made by Fibro as well as the popular US1B original spares produced by Us-Motor

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 E36WL50 by United-Electric and Unimount125E438 spares by Us-Motor are also now also our York Scientific's line-up of service offerings.
