A robot is a programmable machine that can perform complex actions automatically. In production plants stationary robots can be used to process workpieces or carry out assembly work for example. Robots can thus automate the production process and large quantities can be produced efficiently and quickly.
Rolling bearings are used to fix axles or shafts and to ensure an optimal rotation of the mounted components. Rolling elements such as balls cylindrical or tapered rollers are used in the rolling bearing. These are guided between the inner ring and the outer ring. Lubricants are used to reduce the rolling friction. Rolling bearings are available in various sizes. For example relatively small needle roller bearings are used in electric motors while rolling bearings several meters in size are also used in wind farms.
