Oil seals yɛ sealing components a ɛho hia wɔ drive shaft systems mu, a wɔn adwumayɛ nya nnwinnade no adwumayɛ so nkɛntɛnso tẽẽ. Wɔ dynamic friction ne oil contact tebea horow ase no, ɛsɛ sɛ aduru no da ngo a ɛko tia, nea ɛyɛ den a ɛko tia, friction coefficient a ɛba fam, ne thermal aging resistance adi.
