Product Description

 

The correct installation of insert bearings is crucial for their performance and service life. The following are the detailed installation
steps:Preparation before Installation
Clean the components: Use a clean cloth and appropriate cleaning agent to carefully clean the bearing housing bore and the journal surface, removing impurities such as oil, rust, and dust to ensure the surfaces are clean. At the same time, check the surfaces of the bearing housing and the shaft for scratches, pits, and other defects. If there are minor defects, they can be repaired by sanding with fine - grit sandpaper. For serious defects, the components need to be replaced.

 

Check the fit dimensions: Use professional measuring tools, such as calipers and micrometers, to accurately measure the journal diameter and the bearing housing bore diameter to ensure they match the inner and outer diameter tolerances of the bearing. The tolerance range should strictly follow the design requirements. Generally, the journal tolerance is h6 or k6, and the bearing housing bore tolerance is H7.
Prepare installation tools: Get ready suitable installation tools, such as sleeves, hammers, and presses, ensuring they are clean, undamaged, and of the right size.

Structure and Components
Outer Ring: The outer ring has a spherical design, which provides an automatic self - aligning function.
Inner Ring: The inner ring mates with the shaft and is usually equipped with a locking device (such as a set screw or an eccentric sleeve) for easy installation and fixation.
Rolling Elements: Typically made of steel balls, they are used to bear loads and reduce friction.
Cage: It holds the rolling elements in place to ensure smooth operation of the bearing.
Sealing Device: It prevents contaminants such as dust and moisture from entering the inside of the bearing, thus extending its service life.Bearing Housing: Some insert bearings come with a housing (e.g., Pillow Block Bearings), which facilitates direct installation onto the equipment.
Main Features

 

Automatic Self - aligning Function: Thanks to the spherical design of the outer ring, it can automatically compensate for misalignment between the shaft and the bearing housing, adapting to shaft deflection and installation errors.
High Load - carrying Capacity: It can withstand relatively large radial loads and a certain amount of axial loads, making it suitable for complex working conditions.
Easy Installation: Insert bearings with a housing have a compact structure, which are easy to install and disassemble without complex alignment adjustments.
Excellent Sealing Performance: Equipped with high - efficiency sealing devices, they prevent contaminants from entering, thereby extending the bearing's service life.
High Durability: Made of high - quality steel and using advanced manufacturing processes, they have high strength and wear resistance.
Low Maintenance Cost: With a simple design and convenient lubrication, the maintenance cost is low.

Summary
Insert bearings, with their features of automatic self - alignment, high load - carrying capacity, easy installation, good sealing performance, and high durability, are an ideal choice for industrial equipment. Whether it is heavy - industry equipment or light - industry machinery, insert bearings can provide efficient, stable, and cost - effective solutions.
Design and Structural Advantages
Unique Spherical Outer Surface Design: The outer ring surface of insert bearings is spherical, which mates with the concave spherical surface of the bearing housing. It can automatically compensate for the misalignment of the axis caused by installation errors, shaft deflection, etc. The maximum self-aligning angle can reach ±2° - ±3°, effectively avoiding local overload and wear, and extending the service life of the bearings.
Compact and Integrated Structure: The bearing, bearing housing, and sealing device are integrated into one unit. It has a compact structure, occupies less space, and is simple and quick to install, reducing the installation cost and time. For example, in some mechanical equipment with limited space, the compact design of insert bearings can save a lot of space and make the overall layout of the equipment more reasonable.
Performance Advantages
High Load - Carrying Capacity: Through the optimized internal structure design and the selection of high - strength materials, insert bearings can withstand relatively large radial loads and a certain amount of axial loads. Taking the common UCP series insert bearings as an example, they can withstand radial forces of up to several thousand Newtons, meeting the working requirements of various industrial equipment.
Good Rotational Accuracy: Advanced processing technology and precision manufacturing equipment are adopted to ensure the rotational accuracy of insert bearings. During high - speed operation, they can maintain a stable rotation speed and low vibration, improving the operational stability and reliability of the equipment.
Low Friction Coefficient: Special materials and surface treatment processes result in a low friction coefficient during the operation of insert bearings, reducing energy consumption and improving transmission efficiency. At the same time, low friction can also reduce the heat generation of the bearings and extend the service life of the lubricant.
Environmental Adaptability Advantages
Good Sealing Performance: They are equipped with high - performance sealing devices, such as rubber seals or dust covers, which can effectively prevent dust, moisture, and impurities from entering the inside of the bearings, protecting the bearings from the erosion of the external environment and being suitable for various harsh working environments.
Strong Corrosion Resistance: Some insert bearings are made of corrosion - resistant materials or undergo special surface treatments, such as galvanizing or chrome plating, and have good corrosion resistance, enabling them to work normally in wet and chemically corrosive environments.
Maintenance and Cost Advantages
Easy to Maintain: The structural design of insert bearings makes their maintenance work simple and convenient. When it is necessary to replace the lubricant or conduct inspections, there is no need for a complex disassembly process, reducing the maintenance difficulty and cost.
High Cost - Effectiveness: Insert bearings have a relatively low price. At the same time, they have a long service life and good performance, providing users with high cost - effectiveness. On the premise of meeting the equipment performance requirements, they reduce the equipment procurement cost and operating cost.
