NG waterproof flange bearing F2 Ø40, 2-bolt, open cover

NG40F21

The NG40F21 is a robust, medium-sized NG waterproof flange bearing, constructed as a 2-bolt F2 flange unit, engineered to provide precise shaft support and reliable alignment for Ø40 mm shafts. With a bolt hole distance of 144 mm, it integrates seamlessly into conveyor systems and processing equipment where stable alignment and hygiene are essential.

This bearing combines a stainless steel bearing insert with a durable polyurethane housing, offering excellent resistance to corrosion and aggressive cleaning agents. Designed with an open cover and equipped with high-quality nitrile rubber (NBR) seals, it ensures dependable protection against dust, water, and cleaning chemicals. Certified to IP66/67, it is well-suited for environments that require frequent high-pressure washdowns, making it particularly valuable in food, beverage, and pharmaceutical production. The eccentric locking collar provides secure attachment to the shaft, minimizing the risk of slippage under load. Manufactured in Denmark under strict quality standards, the NG40F21 delivers long service life, reduced maintenance, and consistent, hygienic operation.
