3. Seal types and numbering system

  • Prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside
  • Rubber oil seals have to perform in extreme conditions. Therefore, we accommodate all relevant conditions (mechanical and thermo-chemical phase) to maintain the integrity of the rubber oil seal in these circumstances.

    ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).

    However, the report also notes that the oil seal market faces several challenges, including the need for increased research and development to develop more efficient and durable sealing solutions, as well as rising raw material prices and trade tensions that could impact the supply chain.

    Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

    Spare parts, as the name suggests, are replacement components kept on standby to replace worn-out or damaged parts. They are the lifeblood of a machine, ensuring minimal downtime and continuous operation. A well-stocked inventory of spare parts allows for swift repairs, reducing the risk of production halts and financial losses. The importance of having readily available spares cannot be overstated, especially for critical systems where a breakdown could lead to severe consequences.

    Before removing the cover, note the positions of any pipes and wires round it or fixed to it, which have to be removed before it can be freed.
