Technical Characteristics

Technical
Procedure

1. Seal  sheet

2. Support thrust ring

3. Pivot

4. Outer ring

5. Cylindrical rollers

6. Seal sheet


The main characteristic of this series of rollers is the high thickness of the outer ring, which is suitable to bear specific high pressures and the impacts that characterize the use of these bearings (ex. cam followers).


Other important features of these bearings are:

Outer ring with double border of the rollers obtained entirely on the outer ring and accurately grinded to allow the roller to bear loads with axial components. The ring is usually cambered on the outer part, in order to improve working condition with heavy loads and to prevent the concentration of load onto side bands of the raceway. Rollers with cylindrical outer surface can be supplied on request.Pivot with threaded shank, one guide border of rollers obtained entirely and tempered rolling raceway.


On the front part, a seat for hexagon wrench or for corkscrew (on request) can be foreseen.

Sealing steel sheets forced on the outer diameter to form a safe labyrinth protection system.

Full complement of grinded flat-head cylindrical rollers.

Lubrication channels and holes in the pivot.

Tolerance of execution according to normal class, possibility of special execution according to class P5 (DIN 620).
