Regal Beloit Corporation (Beloit, WI) has announced that its Sealmaster PN Gold mounted ball bearings have achieved third party IP69K certification. The IP69K rating is for high-pressure, high-temperature washdown applications; enclosures conforming to it must not only be dust-tight, but also able to withstand high pressure and steam cleaning.
The Sealmaster PN Gold mounted bearings now join the Leeson Extreme Duck Ultra motor and the Hub City Hera stainless steel gear drive as third party IP69K-certified products from Regal. Together, these three products provide a complete washdown solution for food and beverage, pharmaceutical and chemical processing applications. When compared to competing seal designs, the high-performance, triple-lip seal provides superior resistance to water ingress in laboratory testing. In addition, the high- phosphorous, nickel-coated raceways resist corrosion, and the 316 passivated stainless-steel housing or high-strength composite housing make it a robust washdown solution.
