Parker LORD Announces New AS350 Main Rotor Spherical Bearing

 New Part Manufacturer Approval Also Offers Considerable Customer Savings 


CARY, NC., January 11, 2021 – The Parker LORD Noise, Vibration and Harshness Division of Parker Hannifin Corporation, the global leader in motion and control technologies, has received the Federal Aviation Administration’s (FAA) Parts Manufacturer Approval (PMA) for its enhanced Main Rotor Spherical Bearing for the AS350 helicopter. Customers using the Parker LORD PMA parts can reduce their aircraft-on-ground time and save on costs over a new purchase from the original manufacturer.  The PMA part (P/N 704A33-633-211LORD) is now available at and is available to ship immediately from Parker LORD and its preferred channel partners. 


“We are thrilled to offer this spherical stop PMA to the marketplace because it allows operators of AS350, H125, EC130 and H130 helicopters to reduce costs without compromising on safety,” said Rodolphe Leroy, Manager, Global Sales, Business Development and Marketing, Parker LORD. “With parts in stock and the availability to ship globally, there is minimal downtime for the customer.”


The new bearing is designed using Parker LORD’s SPE IIA elastomer, the newest generation of elastomers specifically formulated to withstand the rigors of helicopter flight. The specially formulated elastomer maintains mechanical properties with little to no degradation at elevated temperatures, as well as superior metal surface coatings for increased corrosion protection.

 “Once we fully reverse engineer the OEM part to determine geometry and performance, we can then apply our considerable elastomeric component design experience, analysis tools, and best practices in the new PMA, Repair, or STC design to incorporate improvements when possible to increase part life, improve safety, or reduce maintenance,” says Conor Marr, Staff Engineer. “Designing, manufacturing, and ensuring the safety of parts like these is what we do every day at Parker LORD. That’s one reason why we’re the first choice for both OEMs and the aftermarket.”


This PMA program meets or exceeds the Airbus Helicopters Component Repair and Overhaul Maintenance Program.
