As the most commonly used bearings, radial bearings keep machinery and products moving in industries the world over. BNL’s plastic radial bearings are popular alternatives to steel that: • Require less energy to operate • Are lightweight and low friction • Withstand chemical and corrosive environments • Do not need lubricants • Withstand magnetic and electrical interference Our product range includes full complement bearings, miniature bearings with flanges, keyways and shields. All our radial bearings are made in Acetal with stainless steel balls. They are also available in other materials such as Polypropylene, or with glass balls. For radial bearings that need to withstand high temperatures and exposure to harsh chemical environments, please see our Speciality Bearing section, which contains bearings made from UHMWPE or PEEK and with ceramic, glass or Polyethylene balls. If you require a specific material combination or you need advice on which type of bearing would be best for your application, please contact us.
