What is Tapered Roller Bearings?

Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearing have tapered raceways. According to the number of rows installed, this type of bearing is divided into single-row, double-row, and four-row tapered roller bearings. Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing handles the radial load, it will produce an axial component force. It needs another bearing that can bear the axial force in the opposite direction to balance it.

What is the Characteristic of a Taper Roller Bearing?

The tapered roller bearing type code is 30000, and the tapered roller bearing is separable. Under normal circumstances, especially in ISO 355: 2019 “Rolling bearings-Tapered roller bearings-Boundary dimensions and series designations,” the tapered roller bearing outer ring and inner components within the size range involved are 100% interchangeable. Change used.

The outer ring’s angle and the outer raceway’s diameter are the same as the external dimensions and standardized. It is not allowed to change during design and manufacturing. As a result, the tapered roller bearing’s outer ring and inner assembly can be interchanged worldwide.

Tapered roller bearings are mainly used to bear combined radial and axial loads, especially radial loads. Compared with angular contact ball bearings, the bearing capacity is large, and the limit speed is low. Tapered roller bearings can bear axial load in one direction. They can limit axial displacement of the shaft or housing in one order.

What is the Purpose of Taper Roller Bearing?

Single row tapered roller bearings are typically used in applications with combined loads. Single row tapered roller bearings can also be used in sets. Single row tapered roller bearings can be matched face-to-face, back-to-back, or in tandem to deliver specific advantages depending on operating conditions.
Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills, and machines in the mining industry.
Four-row tapered roller bearings are used almost exclusively in work roll applications such as rolling mills.
