  • Ball vs. Sleeve: A Comparison In Bearing Performance

    2015-6-12 · Ball vs. Sleeve: A Comparison in Bearing Performance Point of Contact – continued This system generates a good deal of friction. Ball bearings are point contact bearings, which generate minimal friction. Previously, opponents of ball bearing fans argued that the ball bearing system could lead to brinelling or indentations in the raceway.

  • Ball vs. Sleeve A Comparison in Bearing Performance

    A sleeve bearing has a single internal rotating cylinder present in a metallic groove or sleeve. It is porous and self-lubricating. Its design has just two moving parts, the outer sleeve and the inner rotating cylinder, unlike ball bearings, which have a number of spherical metal balls lined up on its inside.
