Product Description
Product Detail
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 angle. 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).
Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in material, but also are much stricter in process and precision control than ordinary bearings. During the working process, the stainless steel bearings work stably, have low noise, are corrosion-resistant, and are widely used.

Can you Explain the Design and Construction of Tapered Roller Bearings?
The design and construction of tapered roller bearings are characterized by their conical geometry and specific components that enable them to handle radial and axial loads simultaneously. Here’s an overview of their design and construction:
- Components:
Tapered roller bearings consist of the following components:
- Inner Ring:
The inner ring has a conical raceway on its inner surface, which matches the conical shape of the rollers. It serves as the raceway for the rollers and provides support to the rotating assembly.
- Outer Ring:
The outer ring also features a conical raceway on its inner surface that complements the shape of the rollers. The outer ring provides a rigid structure to house the entire bearing assembly.
- Tapered Rollers:
The rollers have a conical shape with varying diameters along their length. This design allows the rollers to make point contact with the inner and outer raceways, distributing loads efficiently.
- Cage:
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.
