Power steering is a system for reducing the steering effort on cars by using an external power source to assist in turning the wheels. It works by using a belt-driven pump to provide hydraulic pressure to the system. This hydraulic pressure is generated by a rotary vane pump, which is driven by the vehicles engine. As the speed of the engine increases, the pressure in the hydraulic fluid also increases.
Power steering seals are applied to many areas such as automobiles, and trucks. The power steering seals design can resist high pressure and form double protections. It is suitable for application in the power steering with reciprocating movement. It is adequately applicable in the rack and pinion structure.
