MESYS Calculation Software


Needle bearings can be calculated using the selection ‘Cylindrical roller bearing’, too. The type ‘needle bearing’ was only added so the types can be separated in the database.

Needle bearings do not support axial forces. Therefore ‘ux’ has to be selected as input instead of ‘Fx’. The axial clearance is not available as an input.

For drawn cup needle roller bearings the bm-factor for the dynamic load capacity should be set to 1.0 instead of 1.1 in case of machined bearing rings. The type can be selected under options for the bearing type using the all_img3-button behind the bearing type.
