• Plain Bearings are really no bearing at all - the wheel rides directly on the axle
  • Delrin is an acetal resin molded into a flange-type bearing and requires no lubrication
  • Ball Bearings feature a sealed, hardened inner and outer raceway, and hardened steel balls, press-fitted into the hub for high-load and higher speed capabilities
  • Roller Bearings have a split-sleeve hardened spring steel outer race combined with a hardened roller and cage assembly for higher load capacities and smoother rolling under heavy conditions
