Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of synthetic and conventional base oils, plus some additives, for extra resistance to oxidation and excellent low-temperature properties. Synthetic blends make it easy for drivers to make the switch from conventional to synthetic oil, which is why this type of oil is becoming increasingly popular among today’s savviest drivers. It’s also a great middle ground for drivers who want the added protection and performance of a synthetic oil, but might not be ready to foot the bill for a total switch to full synthetic oil.

Silicone rubber (VMQ)
FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.
Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.

DIN
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.
