32038JR Tapered Roller Bearing
Classification :
PRODUCT DETAILS
A single row tapered roller bearing has an outer ring, an inner ring and an inner ring assembly consisting of a set of tapered rollers enclosed by a basket cage.
The conical Angle of the outer ring raceway of a single row tapered roller bearing is between 10° and 19°, which can withstand the combined action of axial load and radial load at the same time. The larger the cone Angle, the greater the ability to bear axial load. Bearings with large tapered angles, rear code plus B, cone Angle between 25°~29°, it can bear large axial load. In addition, single-row tapered roller bearings can be adjusted during installation.

Characteristics of tapered roller bearings:
1. High speed, high precision
2.High rigidity, impact resistance, vibration resistance
3.Can bear large axial load
4.With high rolling contact fatigue strength
5.With high hardness and high mechanical strength, high wear resistance
How to install tapered roller bearings?
Adjusting axial clearance For the installation of tapered roller bearing axial clearance can be adjusted by adjusting nuts on the journal, adjusting gaskets and threads in the bearing seat hole, or by pre-tightening springs and other methods. The size of axial clearance is related to the arrangement of bearing installation, the distance between bearings, the material of shaft and bearing seat, and can be determined according to working conditions.
For tapered roller bearings with high load and high speed, the influence of temperature rise on axial clearance must be considered when adjusting clearance, and the reduction of clearance caused by temperature rise must be estimated. That is to say, the axial clearance should be properly adjusted to a larger extent.
For bearings with low speed and bearing vibration, no-clearance installation should be adopted, or pre-load installation should be applied. The purpose is to make the tapered roller bearing roller and raceway have good contact, uniform load distribution, prevent the roller and raceway from vibration impact damage. After adjustment, the size of axial clearance is tested with a micrometer.
