Rolling bearings | SKF

Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.

iglide® Plastic Bushings: The Self-Lubriing Effect | igus®

The Self-Lubriing Effect. iglide® plastic bushing materials consist of base plastics, fibers and filling materials, and solid lubricants . These components are not applied in layers, but homogeneously compounded. The advantage of this construction becomes clear if you consider the following: 1. The coefficient of friction, determined by the

Full Ceramic and Ceramic Hybrid Bearings by Boca Bearings :: Ceramic Bearing …

Long life and the need for minimal lubriion make this material appropriate for extreme appliions. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.
