  • 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 bearing seals: Types, options, and applications

    2018-1-2 · I think the only reason ball bearings fail to win comparisons100% is that they do have a rubber seal and this can drag. If it existed, a low-friction sliding seal on linear ball bearings would be awesome. If you remove the seals from the linear bearings they will probably perform better until they get dirty.
