  • 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.

    Linear ball bearings are an especially efficient type of rolling element ball bearing. They use a hard-rolling ball element to separate two moving parts along a straight line. They seek to provide smooth, low friction linear motion in rotary applications. There are linear ball slide types: radial ball bearings and thrust ball bearings.
