Sewage and Wastewater Bearings

Sewage and wastewater can be a tough environment for bushings, to say the least. Traditional bushings that continuously operate in these dirty, abrasive laden liquid conditions, will often see premature wear leading to a short bearing life. This is not the case with Thordon bearings. As an ideal replacement for greased iron, greased bronze and phenolic bushings, as well as roller bearings, Thordon grease free bushings can be found in a number of applications including pumps, conveyors, screens, drums, flocculators, aerators and grit tanks. Thordon sewage and wastewater bearing grades were specifically developed and engineered to improve the reliability and performance of equipment operating in these harsh conditions. An improvement in bearing performance can significantly reduce maintenance costs and related down time compared to traditional bearing solutions.

Use the Material Selection Guide below to determine which Thordon bearing grade is best for your application.

  • Eliminate grease & associated maintenance costs
  • High abrasion resistance
  • Improved vibration/shock absorption
  • Easily machining and installation
