Products Application for Automobile steering systems Description
In automobile steering gear systems, FFKM (perfluoroelastomer) O-ring material can be used for the following key accessories
Steering column seal
The steering column is the component that connects the steering wheel and the steering mechanism. FFKM O-rings are used at the steering column connection joints to provide sealing properties to prevent leakage of liquid or gas.
Power steering pump seal
The power steering pump is a device that provides steering assistance. FFKM O-rings can be applied to the sealing of power steering pumps, including the connection between the pump body and the pump shaft, to ensure that the liquid does not leak.
Steering mechanism seal
The steering mechanism is a key component that controls wheel steering. FFKM O-rings can be used in connection joints of steering mechanisms and seals on rotating shafts to prevent leakage of liquids or lubricants.
Steering rod seal
The steering rod is a key component that transmits steering commands to the wheels. Use FFKM O-rings on the connecting joints of steering tie rods and piston rods to ensure liquid or gas sealing performance.
Steering column adjuster seal
The steering column adjuster is a device used to adjust the height and tilt angle of the steering column. FFKM O-rings can be used to seal steering column adjusters to prevent leakage of liquid or gas.
The application of FFKM O-ring material in these accessories is mainly based on its excellent high-temperature tolerance, chemical corrosion resistance and good sealing performance. They ensure proper operation of the steering gear system, prevent leakage of fluids and gases, and provide long-term reliability and durability. It should be noted that the specific material of the O-ring used depends on the vehicle manufacturer's design requirements and specifications.
What is DIN 3771?
DIN 3771 is a standard developed by the German Industrial Standardization Organization (DIN) that specifies the dimensions and marking system for rubber O-rings. This standard defines parameters such as diameter, section thickness, and tolerances for O-rings of different sizes and provides a marking system for them for use in industry and engineering.
According to the DIN 3771 standard, the size of O-rings is expressed in terms of inner diameter and cross-sectional diameter, and specific codes and numbers are used to mark O-rings of different sizes. For example, an O-ring marked "12 × 2" means it has an inner diameter of 12 mm and a cross-sectional diameter of 2 mm.
