Tapered roller bearings, unlike other types of bearings, are equipped with a cone and a raceway. While the cup consists of an outer ring, the cone assembly is made up of rollers, a cage, and an inner ring. Thanks to them, the entire structure transfers combined loads while providing low friction during the operation of the machine in which the tapered bearing is mounted. They can be easily adapted to specific loads, operating speeds, temperatures, vibration conditions, and pollution levels. By fitting one tapered bearing to another tapered bearing, and applying preload, a rigid bearing is obtained as a result. In the offer of ROMBOR from Częstochowa, a metric tapered bearing is available 32004 P6 BBC-R from the manufacturer of parts for cars and agricultural and industrial machines BBC-R.
