Ring – Oil Feed – Precision Oil Distributor Ring for Jet Engines

The Ring – Oil Feed is a critical component in modern turbofan and turbojet engines, supplying a controlled and consistent flow of lubricating oil to bearings, rotating shafts, gear trains, and turbine stages.

Jetsys Defence indigenously engineers high-reliability Oil Feed Rings / Jet Engine Oil Feed Rings / Oil Distributor Rings designed to operate in extreme temperatures, vibration zones, and demanding pressure conditions.

Built with aerospace-grade metallurgy and exacting tolerances, our Oil Feed Rings deliver uniform lubrication, prevent dry-spots in rotating assemblies, and support long-life engine health — making them essential in civil and military aircraft.

What is a Ring – Oil Feed?

A Ring – Oil Feed is an annular precision component that distributes oil from the lubrication supply line into rotating engine parts. Inside a jet engine, it directs oil through drilled passages and spray nozzles, ensuring a stable oil film across high-speed bearings and gear sets.

Why Oil Feed Rings Matter in Jet Engines

Prevent bearing seizure and metal-to-metal contact
Reduce frictional heat and rotor wear
Maintain correct oil pressure and spray distribution
Protect engine during high-RPM conditions
Increase engine lifecycle and overhaul intervals
