NTN Bower 30314HD is a tapered roller bearing set with bearing designation 30314. It has a 70 mm inside diameter, a 150 mm outside diameter and a 38 mm assembled width, with a 35 mm wide cone and a 30 mm wide cup. Dynamic load rating is 230 kN and static load rating is 272 kN, and the tolerance class is ABEC-1; RBEC-1; JIS-0; ISO-Normal.

Tapered rollers ride on angled races, which lets one bearing handle radial and axial load at the same time. A worn or poorly lubricated tapered bearing shows pitting and abrasion on the rollers and races, and it can be picked up as vibration.
