INA bolt roller bearings are structurally similar to single row and double row support roller needle bearings, except that the inner raceway is replaced by large section support bolts with fixed threads and lubrication holes. This type of INA bearing is suitable for applications such as cam drive, bed guide rail, and conveying equipment due to its thick outer ring and rolling element with a specific shape. The bolt type roller can bear high radial loads and also axial forces generated by slight misalignment and skew movements.
