  • Type B: An outer metal case generally used on shafts with diameters under 150mm and bore housing materials made of steel or cast iron. It provides a firm and accurate seal in the housing but may limit the static sealing on the outer diameter (O.D.).

  • Early engines used O-rings (also called packing rings or toric joints) as seals (first patented in 1896). These are just mechanical gaskets in the shape of a torus (a circular ring--like a lifesaver), seated in a groove and compressed during assembly between two or more parts. It creates a seal at the interface. However, O-rings require a fluid film to lubricate them. They have limited usefulness in vacuum application and at extremes of temperature. The modern oil seal represents a significant improvement over the simple O-ring because it effectively seals in lubrication and prevents contamination from outside under a wide range of pressures and temperatures.

  • Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.

  • 2. **Resisting Pressure** Oil seals are subjected to internal pressures that can cause them to fail if not properly dimensioned. Understanding the seal's dimensions helps ensure it can withstand these pressures without compromising its integrity.

  • 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.

  • Car oil gaskets, an often-overlooked component in the intricate machinery of a vehicle, play a pivotal role in ensuring the smooth and efficient operation of your engine. A gasket, simply put, is a thin, usually circular, seal that prevents leakage between two joined surfaces, in this case, the engine block and the oil pan. It's a small but crucial piece in the complex puzzle that is automotive engineering.
  • The front hub oil seal is an essential component of a vehicle's suspension system. Located at the front of the vehicle, the hub oil seal helps to prevent dirt, debris, and moisture from entering the wheel bearings and keep the lubricating oil inside.

  • In addition to sealing fluids, the oil seal 29x44x7 also helps to keep out contaminants such as dirt, dust, and water. These contaminants can cause abrasion and corrosion of the machinery parts, leading to premature wear and failure. By creating a barrier between the internal components and the external environment, the oil seal helps to prolong the lifespan of the machine and reduce maintenance costs.
