S.N.	Parameter	Journal bearing (Sliding Bearing)	Roller bearing
1	Speed	Operate efficiently in high speed	Operate efficiently in low speed
2	Friction	Power loss due to friction increase at high speeds which requires proper oil flow rate for heat rejection	Lower friction in lower speed but higher friction in high speed
3	Maintenance	Need maintenance, Permanent care about lubrication	Occasional attention required
4	Shocks	Bear the shocks and high loads	Doesn't withstand the shocks and high loads
5	Axial length	Very long to bear the shocks and high loads	Relatively less length
6	Bearing Life	Long life	Short life
7	Failure	Lower possibility of failure occur	Higher possibility to failure occurs
8	Application	Used in higher speed application like turbines and compressors etc	Used in lower speed application like gear box
