Kartiorullajärjestelmät

Kartiorullajärjestelmät, also known as tapered roller bearing systems, are a type of rolling-element bearing designed to handle both radial and axial loads simultaneously. They are characterized by their conical raceways and rollers, which are tapered to match the angles of the raceways. This design allows the bearing to effectively distribute forces along the length of the rollers, providing high load-carrying capacity in both directions.

The tapered design is crucial for their functionality. The inner and outer races have conical raceways, and the rollers are also cone-shaped. When assembled, the geometry ensures that the roller contact occurs at a point along its tapered surface. This specific contact geometry allows the system to resist forces that would tend to push the shaft and housing apart (axial load) as well as forces that would try to push them together (radial load).

Kartiorullajärjestelmät are widely used in applications where heavy loads and combined forces are prevalent. Common examples include automotive wheel bearings, gearboxes, heavy machinery, and industrial equipment. Their ability to handle significant axial thrust makes them particularly suitable for applications like railway axle boxes and large industrial shafts. Maintenance typically involves lubrication, and proper sealing is important to protect the bearing from contaminants. The precise alignment of kartiorullajärjestelmät is critical for optimal performance and longevity.
