Designed to withstand high temperatures
Inboard boots fit on the gearbox or engine side of the driveshaft. They are close to the engine and the exhaust line, which means they withstand exposure to temperatures: 165°C pick and 140°C constant—to withstand rotation, even at high speeds and temperatures.
Retention force from a single part
Trilobe TPE boots have an enclosed retainer which exerts a retention force onto balls and rollers, preventing them from coming out of the tulip. This patented, state-of-the-art process adds reinforced ribs to ensure an excellent clamping force on the tulip, creating a tighter, more reliable, more durable seal.
The retainers for the balls and rollers reduce parts in the half shaft. This process also replaces two or three parts with one, delivering a unique thermoplastic elastomer that is more light-weight, compact, and recyclable at a lower cost. Additionally, the large and small diameter areas can be molded with special shapes to meet your exact requirements.
