Tapered roller bearings are used in the same way as cylindrical roller bearings in the axlebox bearing supports of all types of rail vehicles:
• two single-row tapered roller bearingsas a bearing set
• one double-row tapered roller bearingas a ready-to-mount unit
Ready-to-mount units have an integrated seal, are greased and the clearance is adjusted during manufacture. TAROL units (Tapered Roller Bearing Unit) are also double-row tapered roller bearing units but are available in either metric or imperial dimensions and are supplied with all the necessary retaining elements and fittings. They are mounted on the axle journal using a hydraulic press.
