NTA / NTC / TC
Axial needle roller bearings, combination with axial bearing washers TWA,
Single direction, INCH sizes
|
|
CLI axial cylindrical roller bearings are designed to withstand heavy loads in the direction of the shaft. Depending on the bearing design, the load can occur from one or both sides. Axial cylindrical roller bearings are fundamentally different in design from cylindrical roller bearings and consist of roller rings, housing washers, shaft washers and can be dismantled.
Plese select the bearings in the following tables. Click " CLI BEARING NO. " or " DETAILS " to check the specifications...
