HISPIN® PDR RT HiSpin® PDR RT HiSpin® PDR RT optimizes the performance of rotary wing aircraft gearboxes by ensuring essential lubrication and simultaneously preventing leakage at high rotational speeds. Unique sealing design The unique design of the sealing lip in the HiSpin® PDR RT ensures effective lubrication on one side of the seal and a dry shaft on the other side. Withstanding extremely high speeds at high temperatures, with minimum friction and minimum power loss, it maintains lubrication within the gearbox while keeping the shaft dry. The superior high-speed sealing capability of the HiSpin® PDR RT, not only matches the needs for high speed rotary seals in helicopter gearboxes but also provides longer lifetime of the gearbox assembly, resulting in a better service life for the helicopter and ultimately it contributes to increased safety. Features and Benefits Capable of operational surface speeds up to 60 m/s and beyond Bi-directional sealing capability Compact design reduces assembly space requirement Wide temperature range, from -60 °C to +200 °C Ability to handle pressure Excellent sealing performance with and without lubrication Extremely low friction and heat development Wide media compatibility Negligible shaft wear Design optimized for durability and long service life
