Boston Gear stocks a wide selection of plain cylindrical, flanged, and roll-end bearings in four different materials:

• Nylon, which offers good chemical and corrosion resistance, excellent abrasion resistance, and low surface friction for long wear without lubrication.
• Delrin® and Celcon®, the trademarks for equivalent Acetal resins, which are produced by DuPont^TM and Celanese^TM, respectively, and which possess high moisture resistance characteristics.
• Nylatron® GS, which is a trademark for molybdenum disulfide-filled nylon produced by the Polymer Corp, and which offers superior abrasion resistance.
• Teflon®-filled Acetal, a material with first-rate abrasion and corrosion resistance and high lubricity against steel.
