- The Spark Plug was a motion-controlled device that connected to the PlayStation 3 via USB. It consisted of two joysticks, each mounted on a flexible arm, which could be positioned in a variety of ways to mimic the movements of the player's hands. The device was designed to be used in conjunction with the PlayStation Move, Sony's motion-control system, but it also worked with a wide range of games that supported traditional controllers.
Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.


Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
With minor lip type Used for applications where there are contaminants, such as dust and foreign matter, on the air side face of the oil seal.
