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 Mostek 450-00861-00 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 Motoriduttori products, including obsoleted and phased-out Motorola parts and systems, as well as the all-new for 2023 Moxa 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 Motoriduttori such as the MRV40F1 spares. Related to this we have added to our service line-up the 64W4709B01 manufactured by Motorola and we are pleased to be able to service most Motorola systems and parts. Due to increased demand we now feature UC3111 by Manufacturer Moxa as well.

York Scientific's New & Featured Automation Replacement Parts: Starting early January 2025 YORK has Motion-Controls Brand D49SENCSL6RA1SSMFMGMH in stock, original and quality replacement parts available for immediate dispatch to meet your requirement for spare replacements. Spare units by Motortronics such as CSD2P5E equipment made by Motortronics have been added to our featured items. As a tip, you can find the entire Motortronics products line-up in our inventory by simply searching for "Motortronics" in the search box. Additionally we have now also available 5718L03P12 made by Lin-Engineering as well as the popular MS4800S301440XampR original spares produced by Omron

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 XPE00U3S2H000100 by Ultimax and CSD2P5E spares by Motortronics are also now also our York Scientific's line-up of service offerings.
