NNK is committed to the best raw materials, and uses advanced technology and equipment to solve oil seal problems for customers. Our products not only ensure the sealing effect, but also minimize the friction force. The service life is longer than the average service life of oil seals. less loss.
Production processes also play a significant role in determining the price of oil seals. Advanced manufacturing techniques and quality control measures can increase production efficiency and reduce waste, leading to lower costs and potentially lower prices for consumers. However, these technologies may also require significant investments in equipment and training, which could initially increase the cost of producing oil seals.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).
Advantages:
– Good static sealing
– Compensation of different thermal expansion
– Reduced risk of fretting corrosion
– Higher bore surface roughness is allowed
– Installation in split-housings
– Modern lip design provides low radial forces
Installation techniques must be carefully selected and executed to ensure the seal functions correctly throughout its service life. Each technique addresses specific installation needs and ensures long-term reliablity.
