Plastic Vs Steel

Lubrication Free: Steel bearings require lubrication to reduce friction, dissipate heat and prevent corrosion. Due to the design of plastic ball bearings, there is no metal to metal contact, which results in less friction. Many times the liquids the bearings are running in can dissipate heat and act as the lubricant.
