  • To increase the pressure around the shaft and maintain the seal’s integrity, certain lip seals have an extra spring looped into the flexible rubber part.

  • The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s. 

  • In addition to replacing the spark plug, it's also a good idea to inspect and clean the spark plug regularly to ensure that it's in good working condition. Check for signs of wear or damage, such as cracked porcelain or worn electrodes. If you notice any issues, it's best to replace the spark plug immediately to prevent further damage to your snowblower.

    It is recommended for use in oil which contains load bearing additives such as EP gear oils

  • This refers to the component of the oil seal that makes contact with the shaft.
    It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
