4713379 BRG TAPERED For HITACHI ZW310-7 QSM11

Tapered Roller Bearings, referred to as TRB, are a special type of bearings, mainly used to support the gear shaft of the shaft drive gear, which is easy to achieve a 90° direction change when transferring power. ‌ Such bearings are usually used in pairs to ensure smooth rotation and rigidity at the point of engagement of the gear ‌. Compact and lightweight, with high load carrying capacity and durability.Tapered Bearings are mainly used to bear radial and axial loads and are often used in pairs to balance the thrust loads caused by the conical geometry of the bearings. ‌ This bearing design includes a conical inner raceway (called a cone) and a conical outer raceway (called a cup), as well as a conical tapered roller. The bearing roller/cage assembly and the inner ring form an inseparable unit that can be mounted independently of the outer ring.
