40X68X10 R1 Metric Oil Seal

As the name indicates, this style of rotary shaft seal is fully enclosed! The main benefit of this style is the very stable construction which in turn offers a better protected sealing member in comparison to the open backed style.This style of seal is the hardest wearing as it seals with a reinforced metal case and is mainly used on larger shafts when the diameter is greater than 150mm, or when a small shaft requires extra strength. Fully enclosed seals are more commonly single lip but can be supplied with a double lip.
