Regal Beloit Corporation, a leading manufacturer of electric motors, electrical motion controls, power generation and power transmission components, announced that its Sealmaster PN Gold mounted ball bearings have achieved third party IP69K certification.

Ingress Protection (IP) Marking rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact and water. It is published by the International Electrotechnical Commission (IEC). 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.

“Traditionally, IP69K and IP69 ratings have been used for electronic components, but the industry is starting to recognize power transmission components such as bearings with this distinction,” said Ian Rubin, director of marketing - customer experience, Regal. “The Sealmaster PN Gold mounted bearings have been proven to outperform competitors’ washdown bearings and are often specified by end users because of their performance in washdown applications, and now they carry the formal IP69K certification."

“It should be noted the industry standards for IP69 and IP69K have been updated in recent years, with IP69K being phased out and a revised IP69 standard that includes the severity of the IP69K becoming standard. For this product, Regal will use the IP69K terminology in its communications based on the years of the industry knowing IP69K was more severe than IP69," Rubin added. 

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.

Sealmaster PN Gold mounted bearings are available in both setscrew and SKWEZLOC concentric locking collar designs.
