Municipalities around the country rely on waste water treatment facilities to treat sewage and provide reclaimed water. Bearings used in the aeration ponds at these facilities are constantly exposed to water and contamination and must be able to withstand these harsh conditions. Downtime on these ponds can be very costly and create hazards to both the environment and local constituents.

NTN’s SPAW heavy-duty mounted bearing units offer a superior one-piece solid ductile housing design and robust seals which allow them to withstand the severely contaminated and corrosive environments of waste water treatment plants better than the often-used SAF style bearing units.

Our products can handle your most extreme.

NTN precision-engineered bearings are proven to be durable and dependable. Plus they’re readily available in a wide variety of fittings and come with hands-on support from experienced field engineers, all working to help you boost production like never before.
