BT4B 334031/HA4C1800 Bearing

rolling mill bearings BT4B 334031/HA4C1800 BT4B 334031/HA4C1800 four row tapered roller bearings


TQO bearings BT4B 334031/HA4C1800 is directly mounted and comprised of two double inner races, two single and one double outer race, with an inner race spacer and two outer race spacers. Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck.  

The inner race spacers are hardened to minimize face wear.
