Air-Tight Bearing and Hub Solutions
Air-Tight LLC was founded in 2003, originally providing wheel bearing protection systems that were installed on recreational boat trailers. We later expanded our focus on additional applications and markets for bearing cavity protection technology. Our bearing cavity pressurization systems work by hermetically sealing the bearing cavity, pressurizing the cavity with low air or nitrogen, controlling and monitoring the bearing cavity 24/7 with the end results of eliminating ingress contamination period. “Protection by the Laws of Physics”.
