Winter 2022 & 2023 Q1 Developments in Industrial Automation - expanded product offering and diagnostic and repair services at York MRO

Winter 2023 Update: Since December 2022 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at York MRO 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 Koyo SR-21-EX 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 Lenze products, including obsoleted and phased-out Limitorque parts and systems, as well as the all-new for 2023 Mistubishi product line-up. Starting Q1 2023 York MRO is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader Lenze such as the ESV113N04TXB spares. Related to this we have added to our service line-up the L12010 manufactured by Limitorque and we are pleased to be able to service most Limitorque systems and parts. Due to increased demand we now feature MRJ2S45KB4QN140 by Manufacturer Mistubishi as well.

York Scientific's New & Featured Automation Replacement Parts: Starting early January 2023 York has Mistubishi Brand MRS11200E01 in stock, original and quality replacement parts available for immediate dispatch to meet your requirement for spare replacements. Spare units by Mistubishi such as FRA24075KAW equipment made by Mistubishi have been added to our featured items. As a tip, you can find the entire Mistubishi products line-up in our inventory by simply searching for "Mistubishi" in the search box. Additionally we have now also available MRS380BBE01 made by Mistubishi as well as the popular CIMRG3U4037 original spares produced by Magnetek

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 FRA240E075KUL by Mistubishi and FRA24075KAW spares by Mistubishi are also now also our York Scientific's line-up of service offerings. This also includes the original A74GA11B Spares made by industrial controls and automation manufacturer Mistubishi.
