2 Bearing Selection and Shaft and Housing Design
Technical Data Bearing accuracy Accuracies of rolling bearings that is dimensional accuracy and running accuracy of rolling bearings are defined by applicable ISO standards and JIS B 1514 standard (Rolling bearings - Tolerances) (Tables 2 4 and 2 5) The dimensional accuracy governs the tolerances that must be satisfied when mounting a
Interactive bearing selection
"Plain bearings" and "Seals" are other self-contained sections The CD also includes calculation routines with automatic input from the bearing tables Full technical data are presented for more than 16 000 products both in table and drawing form DXF files of the cross sections of most common bearing types can be exported to CAD systems
Maximum Speed
For example precision angular contact bearings should be limited to around 850 000 dN Deep groove radial ball bearings with standard metal retainers should not exceed around 250 000 dN Of course with modifications to materials and design these values can be exceeded such as improved retainer design ceramic hybrids and improved lubrication
