Helicopter Swashplate

Product catalog summary

Introduction
The document discusses the critical role of Omniseal® rotary lip seals in helicopter main rotor swashplates, particularly in challenging environments like deserts or over the sea, where contaminants can cause significant damage.

Environment Challenge
The swashplate is connected to the main mast and requires a large rotary seal (up to 50 cm or 20 inches). The shaft operates at variable speeds, reaching up to 9 m/s (1,700 ft/min). The seal must prevent leakage and protect the bearing cage from environmental pollutants.

Solution
Omniseal® rotary lip seals are designed to accommodate large sizes and feature a wiper to protect mechanisms from debris. They can prevent leakage for over 1,000 hours and operate dry if necessary. The seals are trusted for their low friction and wear rate at high speeds.

OMNISEAL® ROTARY LIP SEALS Helicopter Main Rotor Swashplate Arnaud Verger AVIATION HIGH SPEED Environment Flying a helicopter in an unpredictable and changing environment such as the desert or above the sea can lead to the accumulation of several kind of potential, aggressive contaminants, which are not clearly visibly on the bearings of the main shaft of a helicopter rotor. These damaging substances may cause jamming, ultimately leading to crash. The sealing of the swashplate is critical as it protects this aviation equipment from dust, sand and debris.

Omniseal® rotary lip seals are able to accommodate very large sizes (more than 50 cm or 20 inches), featuring a wiper to protect the mechanisms below from any debris or pollutant. The design of the seal may help to retain the bearing cage and prevent any leakage for more than 1,000 hours. Should the oil level be not high enough, the seal has the ability to run dry for a considerable amount of time. Our customer trusts our polymer lip seals due to their low coefficient of friction and low wear rate at high rotary speed with improved sealing performance. • Acts as a rotary seal on the swashplate...
