Methods and Design of the Supporting Seats and Fixed Flange Discs

Due to the thin wall structure of the cross roller bearings, full consideration must be given to the rigidity of the supporting seats or flange discs. When the bearings are split types, they can not evenly fixate inner and outer rings if the supporting seat or flange disc is not rigid enough and if they bear moment loads, distortion will occur, resulting in significant degradation of bearing performance due to the contact conditions of the rollers becoming uneven. To prevent this from occurring, it is recommended to design the supporting seats and flange discs through the following methods:

♦ Supporting seat: it is advised to design the wall thickness of the seats based on more than 60% of the section height of bearings.



Alternatively, screw holes for removing bearings may be set up on the seats; when it is necessary to remove the bearings from seats, the screws may be locked into the threading holes and no damage will occur during the disassembly of bearings by using the screws to top the bearings from the seats.
