The different rolling bearing types have specific characteristics due to their design. Depending on the type, they are suitable for widely differing applications. Ball roller bearings are designed such that they fulfil a range of technical and economic requirements to an excellent degree. This new type can be used to achieve optimum designs for new bearing arrangements and to replace existing bearing arrangements. The following overview shows comparable rolling bearing types and describes their suitability for the requirements placed on a bearing. In the application, the information in this TPI as well as in Catalogue HR 1, Rolling Bearings, must be observed.The bearings are available open as well as with gap seals or lip seals. Designs with gap seals have the suffix 2Z, bearings with lip seals have the suffix 2HRS or 2RSR. Other seal designs are available by agreement. Lubrication Open bearings can be lubricated with grease or oil. Bearings sealed on both sides are greased for life using a lithium soap grease with a mineral oil base.
