  • What types of bearing are very low friction?

    Bearings are designed to limit friction between moving parts. The rings and balls of these bearings are machined to fine tolerances and high levels of roundness to assist in the reduction of friction. Due to this specific design, turning resistance of bearings can be extremely low.
