Frequently Asked Questions
Rubber oil seal is used for pump, but the seal life is short. And the shaft has damage (made groove) due to contact with the lip. Does EBARA suggest any counter measure?
Use of a high-precision labyrinth structure for high sealing performance will make it possible to suppress the infiltration of dust from the exterior and scattering of oil, contributing to environmental improvements.
Also, since it has a non-contact structure, power loss can be prevented and wear on the shaft will not occur.
