Hi; i have a problem about the life time calculation of a bearing in a system. the system includes a shaft and a spiral bevel gear, a double row angular contact ball bearing and a clutch on this shaft. DRACB bearing carry radial, axial, tangential loads and moments. how can i calculate the life...

Thanks Englishmuffin the cage made of steel and it fails from the rivet holes or the radiuses where the ball pocket starts.. what kind of computer prog. did you mention? is there a spesific program about these problem?

Thank you CESSNA1, i think the vibration on the cage depends on the angular velocity.. and if i give an angular acceleration to the or approximately 160 G force occurs on the ball..(so the cage) i think the failure of the cage depends on vibrational fatique.. what is your opinion? Regards

? try to analyse the vibration effects on bearing cage, under the vibration the cage fails after some time,(i think because of fatique= does anybody recomend me a source to understand what happens on yhe cage? and which fea prog. do you recomen to analyse this?

Im looking for nbr and viton material test datas or mooney rivlin constants.. I also checked polymerfem but there is only uniaxial compression test datas for the materials and when i apply these on Msc.Marc i got not very good results.. i would be greatful if you help me..
