According to Rodolphe Leroy, Sales Marketing and Business Development Manager, LORD Corporation, this approval is significant since it is estimated that very few B206 require the tail skid weight for this STC. Operators will benefit from lower maintenance costs, extended life and reduced vibration without affecting cabin load or needing to drill into the tail skid. The STC ensures a dynamically balanced tail rotor hub assembly throughout the life of the LORD tail rotor trunnion kit.
The tail skid weight, included in the LORD elastomer tail rotor trunnion bearing kit (P/N LB2-1010-20-1), is now an optional installation and only required as needed to assist in the dynamic balancing of the tail rotor hub assembly.
The wheel hub assembly plays a critical role in the overall performance of a car or a truck. Its main purpose is to hold the wheel and tire together by providing ample support all the time. This is very important to keep the vehicle moving continuously through the rotation of the wheel and the tire. Bearings are components that make a vehicle's motion possible, allowing moving parts to rotate with minimal friction and taking a load. Without bearings, the vehicle's parts would quickly wear out from friction. Typically, bearings in a vehicle have to deal with radial and thrust loading. Radial load makes the bearing rotate or roll as a result of tension. Thrust load, or axial load, is associated with the bearing's carrying capacity and is applied parallel to the bearing's axis. When it comes to the vehicle, its weight carry a radial load, however, when it goes around a turn, the bearings deal with a thrust load from the cornering forces.
“LORD has decades of experience working with Bell on the 206 as well as other platforms, all with the joint goal of keeping pilots safe, while also minimizing unscheduled maintenance and costs,” said Leroy. “This option further solidifies our offering to provide the long-term flexibility for operators to maintain a proper dynamically balanced tail rotor hub assembly throughout the life of the aircraft.”
