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 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 Motori-Neri products, including obsoleted and phased-out Mrc parts and systems, as well as the all-new for 2025 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 Motori-Neri such as the T56AN4 spares. Related to this we have added to our service line-up the 5214KF manufactured by Mrc and we are pleased to be able to service most Mrc systems and parts. Due to increased demand we now feature DefaultIP192168127253 by Manufacturer Moxa as well.

York Scientific's New & Featured Automation Replacement Parts: Starting early January 2025 York has Motorola Brand FLN3552A in stock, original and quality replacement parts available for immediate dispatch to meet your requirement for spare replacements. Spare units by Motoman such as CACRIR44SFBP00B01 equipment made by Motoman have been added to our featured items. As a tip, you can find the entire Motoman products line-up in our inventory by simply searching for "Motoman" in the search box. Additionally we have now also available JARCRMSR01REVA01MSR016653054 made by Yaskawa as well as the popular CPIP5365 original spares produced by Motorola

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 3HAC36171DSQC50151469030A2 by Motorola and CACRIR44SFBP00B01 spares by Motoman are also now also our York Scientific's line-up of service offerings.
