Plastic Bearing can be highly wear resistance, with a low coefficient of friction and can replace more expensive alternatives in many applications. Plastic Bearings also do not typically need lubrication unless steel balls are used in combination with plastic races. Plastic bearings are designed to maintain a low coefficient of friction over the life of the bearing. Compared to steel bearings, which can become pitted and increase the coefficient of friction, plastic bearings many times last longer. And finally, Plastic Bearings can be used in wash-down applications, salt water and harsh chemicals without compromising performance. Water can even be considered as a lubricant for plastic bearings.
