  • Overall, radial oil seals are an essential component in the operation of rotating machinery. Their ability to create a tight seal, adapt to variations in shaft speed and diameter, withstand high pressures and temperatures, and provide additional benefits make them an ideal choice for a wide range of applications. By selecting the right radial oil seal for your specific needs, you can help to ensure the long-term reliability and performance of your equipment.
  • Spark plugs play a pivotal role in the efficient functioning of internal combustion engines, whether they power our vehicles, power generators, or even small appliances like lawnmowers. These tiny components, often overlooked, are the heartbeat of an engine, igniting the air-fuel mixture to create the power necessary for operation.

  • Overall, twin spark plug technology has transformed the automotive industry, providing drivers with more powerful, efficient, and reliable engines. By incorporating dual spark plugs per cylinder, manufacturers have been able to optimize combustion efficiency, increase engine durability, and improve overall performance. With these advancements, drivers can enjoy a smoother, more responsive driving experience while also reducing their carbon footprint.

  • Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.

  • What is an oil seal and how does it work?

  • The dimensions 40x52x7 denote the outer diameter, inner diameter, and thickness of the oil seal respectively. The first number, 40, refers to the outer diameter, which is the measurement from one side of the seal to the other when it's placed on the outer surface of the component it seals. The middle number, 52, signifies the inner diameter, the size of the shaft or housing bore it fits around. Lastly, the 7mm thickness contributes to the seal's durability and ability to withstand pressure.
  • There are several factors to consider when selecting the right rotary shaft oil seal for a specific application. These include the type of fluid being sealed, the operating conditions, such as temperature and pressure, and the speed of the rotating shaft

  • These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.

  • In conclusion, spark plugs are small but mighty components that are critical to the proper functioning of your car's engine. By ensuring that your spark plugs are in good condition and replaced as needed, you can enjoy better performance, increased fuel efficiency, and reduced emissions. So next time you take your car for a tune-up, don't forget to give your spark plugs the attention they deserve.
  • There are several types of rubber materials used in manufacturing tube gaskets, each with its own set of properties tailored to specific industrial needs. For instance, Neoprene, known for its resistance to oil and ozone, is often utilized in automotive and chemical processing industries. Silicone rubber, on the other hand, with its excellent heat resistance, finds use in high-temperature environments. Viton, with its superior resistance to harsh chemicals and high temperatures, is a go-to choice for the oil and gas industry Viton, with its superior resistance to harsh chemicals and high temperatures, is a go-to choice for the oil and gas industry Viton, with its superior resistance to harsh chemicals and high temperatures, is a go-to choice for the oil and gas industry Viton, with its superior resistance to harsh chemicals and high temperatures, is a go-to choice for the oil and gas industryrubber tube gasket.

  • Unscrew the pulley bolt anticlockwise with a socket and bar. Start it turning with a sharp blow on the bar.

  • The '20' in the Oil Seal 20 34 7 refers to the inner diameter, which is the size of the shaft it will. The '34' denotes the outer diameter, determining the space it occupies in the housing. Lastly, the '7' signifies the thickness or cross-section of the seal, contributing to its durability and sealing effectiveness.
