Page: Comparison between Sliding and Rolling Contact Bearing
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
