130x230x150mm 197726 For Various Rail Transit Vehicles Subways And Light Rails
Product Description
Design features
Bearing steel Tapered roller bearing units were originally developed in the 1950s for American freight cars to substitute plain bearings. The Association of American Railroads (AAR) has standardized these bearings for adapter applications and requires case carburized steel for inner and outer rings as well as rollers. SKF offers a special assortment of inch size TBUs which comply exactly with the AAR specifications. For high-speed and very high-speed applications, both case carburized and through hardened steel is used, depending on the application requirements.

These bearings have tapered rollers which are guided by the thicker side of the cup. The design of the sliding surfaces of the cup and inner ring and the rolling elements when extended converge towards the same single point on the bearing axle. bearing tapered
Double-row and four-row taper roller bearings can bear the radial load and axial load in double directions.
