High mechanical performance and long service life: Rolling bearings are made of bearing steel, which has undergone heat treatment and has high mechanical performance and a long service life.
The advantages and disadvantages of bearings can be analyzed in detail from two aspects: rolling bearings and sliding bearings:
Advantages and disadvantages of rolling bearings
Advantages:
Low friction coefficient and high transmission efficiency: The friction coefficient of rolling bearings is only 0.001-0.005, resulting in high transmission efficiency, low heat generation, and reduced
consumption of lubricating oil.
Standardization, serialization, and generalization: Rolling bearings have achieved standardization, serialization, and generalization, suitable for large-scale production and supply, and easy to use
and maintain.
High mechanical performance and long service life: Rolling bearings are made of bearing steel, which has undergone heat treatment and has high mechanical performance and a long service
life.
High operating accuracy: The internal clearance of the rolling bearing is small, and the machining accuracy of each part is high, resulting in high operating accuracy. The rigidity can be increased
by preloading.
Wide applicability: Some rolling bearings can withstand both radial and axial loads simultaneously, simplifying the structure of the bearing support.
Disadvantages:
Limited load-bearing capacity: Rolling bearings have a smaller load-bearing capacity than sliding bearings of the same volume, with larger radial dimensions, making them suitable for medium
and high-speed applications.
Vibration and noise are significant, especially in the later stages of use, and are not suitable for use in situations where high precision is required and vibration is not allowed.
Sensitive to foreign objects: Rolling bearings are particularly sensitive to foreign objects such as metal shavings and are prone to early damage.
Advantages and disadvantages of sliding bearings
Advantages:
Smooth and noiseless operation: Sliding bearings run smoothly and noiseless, suitable for low-speed and heavy-duty situations.
Simple structure: Sliding bearings do not have complex rolling element structures, and have a small installation space, making them suitable for situations with limited space.
Suitable for high loads: Sliding bearings are suitable for long-term high loads, with a simple structure and low cost.
Strong shock absorption ability: Sliding bearings have good shock absorption ability and are suitable for occasions that require shock absorption.
Disadvantages:
High friction coefficient: Sliding bearings have a high friction coefficient, low transmission efficiency, high heat generation, and require good cooling measures.
High driving torque required: High driving torque is required at high speeds and heavy loads.
High material requirements: The material selection of sliding bearings has a significant impact on their performance and usually requires special lubrication measures.

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.

Characteristics of tapered roller bearings
High temperature resistance: Made of high temperature resistant materials and lubricating grease, it can operate stably in high temperature environments and is suitable for hot rolling mills, hot forging machines, and heat treatment equipment.
