The difference between bearings and shaft sleeves
Release time:
2025-01-10
Bearings are widely used in various machinery, such as automobiles, engineering machinery, metallurgical equipment, etc., to support rotating shafts, reduce friction and wear.
Structural differences:
A bearing is an independent component typically composed of an outer ring, an inner ring, rolling elements, and a cage. Rolling bearings also include components such as seals and lubricating
oil.
The shaft sleeve is usually a part of a bearing, consisting of the outer and inner rings of the bearing. The outer ring is fixed on the body, and the inner ring is sleeved on the bearing.
Functional differences:
The main function of bearings is to support the shaft, reduce the coefficient of friction, ensure rotational accuracy, and withstand the load of the shaft.
The main function of the shaft sleeve is to support the outer ring, protect the bearing from excessive vibration, and reduce maintenance costs. The shaft sleeve extends the service life of the
equipment by reducing direct contact between the shaft and the bearing.
Application scenarios:
Bearings are widely used in various machinery, such as automobiles, engineering machinery, metallurgical equipment, etc., to support rotating shafts, reduce friction and wear.
Shaft sleeves are commonly used in applications that require high-precision rotation and reduced vibration, such as precision instruments and equipment, to protect bearings and extend their
service life.

Uniform force: During installation, avoid hitting only one side or using excessive force. Instead, apply even force to prevent tilting or cracking of the bearings.

The difference between tapered roller bearings and cylindrical roller bearings
Conical roller bearings: They can withstand both radial and axial loads, especially when subjected to larger radial loads, and their performance is superior to other thrust bearings. It can transmit unidirectional axial loads. If it is necessary to transmit axial loads in the opposite direction, another tapered roller bearing symmetrically installed with it is required.
