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 Sterling Instrument S9123A-SG050 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 Stober products, including obsoleted and phased-out Sti parts and systems, as well as the all-new for 2023 Sti 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 Stober such as the ES543235930000000010K202VG0125ES54 spares. Related to this we have added to our service line-up the 426780080 manufactured by Sti and we are pleased to be able to service most Sti systems and parts. Due to increased demand we now feature MSFS43CNTRLB2EAC1 by Manufacturer Sti as well.

York Scientific's New & Featured Automation Replacement Parts: Starting early January 2025 YORK has Sti Brand LCM100 in stock, original and quality replacement parts available for immediate dispatch to meet your requirement for spare replacements. Spare units by Stober such as K402WG0350MT20 equipment made by Stober have been added to our featured items. As a tip, you can find the entire Stober products line-up in our inventory by simply searching for "Stober" in the search box. Additionally we have now also available LCM130 made by Sti as well as the popular 170110030 original spares produced by Sti

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 MS4620350Q2X by Sti and K402WG0350MT20 spares by Stober are also now also our York Scientific's line-up of service offerings. This also includes the original MS4300B Spares made by industrial controls and automation manufacturer Sti.
