NG waterproof flange bearing F3 Ø30, 3-bolt, open cover

NG30F31

The NG30F31 is a compact and robust NG waterproof flange bearing, designed as a 2-bolt F3 flange unit to ensure stable support and precise alignment for Ø30 mm shafts. This bearing integrates seamlessly into medium-duty conveyor systems and processing equipment where hygiene, corrosion resistance, and consistent performance are essential.

It features a stainless steel bearing insert encased in a tough polyurethane housing, delivering excellent resistance to corrosion and harsh cleaning chemicals. Designed with an open cover and equipped with high-quality nitrile rubber (NBR) seals, it reliably protects against dust, water, and cleaning agents. Rated to IP66/67, the NG30F31 is purpose-built for installations that require frequent high-pressure washdowns, making it particularly well suited for food, beverage, and pharmaceutical applications. The eccentric locking collar ensures secure attachment on the shaft, minimizing slippage under load. Manufactured in Denmark under strict quality standards, this bearing offers long service life, low maintenance, and dependable, hygienic operation.
