Product Description

Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. There are 2 kinds of small cone angle and large cone angles. The small cone angle mainly bears the combined radial and axial loads dominated by radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately, and the radial and axial clearances can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial loads, which are mainly axial loads. Generally, it is not used to bear pure axial loads alone but can be used to bear pure radial loads when arranged in pairs (the ends with the same name are installed opposite to each other).

Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row, and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can bear radial loads and axial loads in 1 direction. When the bearing is subjected to radial load, an axial component force will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.

The cage or retainer holds the rollers in position, maintaining proper spacing and preventing them from coming into contact with each other. The cage material can vary, and its design may affect factors like friction and heat generation.

  • Conical Geometry:

The distinguishing feature of tapered roller bearings is their conical geometry. The conical angle is defined by the contact angle between the roller axis and the bearing axis. This angle facilitates effective load distribution and axial load support.

  • Load Distribution:

The conical shape of the rollers and raceways allows tapered roller bearings to handle both radial and axial loads. Radial loads are primarily supported by the larger diameter of the rollers at the large end of the cone, while axial loads are absorbed by the smaller diameter near the small end of the cone.

  • Adjustable Clearance and Preload:

Many tapered roller bearings allow for adjustable internal clearance or preload. This feature enables fine-tuning of the bearing’s internal play, optimizing performance and minimizing friction.

  • Thrust Capability:

Tapered roller bearings can handle thrust (axial) loads in one direction, making them suitable for applications where axial loads need to be managed along with radial loads.

  • Applications:

Tapered roller bearings find applications in various industries, including automotive, heavy machinery, aerospace, and more. They are used in scenarios that require efficient load distribution and handling of combined loads.

In summary, tapered roller bearings are designed with conical geometry to accommodate both radial and axial loads. Their specific components, such as tapered rollers and a cage, work together to ensure effective load distribution, making them suitable for a wide range of industrial applications.
