- Labor Reduction Automation and advanced technology reduce the reliance on manual labor, an essential factor given the ongoing labor shortages in agriculture.
Acrylonitrile-buta-diene natural rubber (NBR - Nitrile)
These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
Replace the sump drain plug tightly and refill the engine with the right amount and grade of oil.
The rubber material used in the oil seal should be selected based on the operational temperature and substance to be sealed.
Table 5 lists the major rubber materials along with their operational temperature ranges.
Note that it is necessary to check the compatibility with fluids.
<N.B.>
Extreme pressure additives are compounds added to the lubricant. They are activated by heat and chemically react against rubber, which deteriorates rubber properties. For this reason, it is necessary to check for compatibility with rubber materials.

What materials are available?
Out of all of the elastomers, silicone offers you the widest range of working temperature ranges. Renowned for its flexibility and low compression set capabilities, silicone is the optimal choice for o rings and other moulded seals.
