Advantages and Disadvantages of Square Bearing Seats


advantage:


Square bearing seat1. Excellent material: Square bearing seats are mostly made of high-quality cast iron materials, which have high hardness, strength and wear resistance, ensuring their long service life.


2. Reasonable structure: The structural design of the square bearing seat is relatively simple and easy to process, install and maintain. At the same time, it is highly tolerant and can be applied to different shaft diameters, axial loads and rotational speed requirements.


3. High stability: The square bearing seat has a compact structure, which can effectively reduce friction and wear between the bearing seat and the bearing, thereby ensuring smooth operation, low noise, and low vibration of the bearing seat.


4. Wide scope of application: Square bearing seats are suitable for various bearing forms, such as spherical, roller, etc., and can be used in many fields such as metallurgy, mining, electric power, and engineering machinery.


shortcoming:

1. High installation requirements: The installation accuracy and parallelism requirements of square bearing seats are relatively high. If installed improperly, air, moisture, pollutants, and foreign matter will enter between the bearing and the sliding bearing, causing damage to the bearing or even failure.


2. Temperature range limitation: The operating temperature range of square bearing seats is relatively strict. Some high-speed and heavy-load equipment must use centralized lubricating grease or cooling systems. Otherwise, the bearings will overheat, be damaged, and affect the service life.


3. Single lubrication method: Square bearing seats generally adopt centralized lubrication method, and excessive lubrication methods cannot be used, which limits its scope of use and effect to a certain extent.


The square bearing seat has the advantages of excellent material, reasonable structure, high stability, and wide application range, but its shortcomings such as high installation requirements, limited temperature range, and single lubrication method cannot be ignored. Therefore, when selecting a square bearing seat, it is necessary to comprehensively consider its quality, use environment, installation conditions and many other factors according to the actual situation to ensure its normal use and long-term operation.



What materials are square bearing seats made of?


Cast iron square bearing seat

Cast iron square bearing seat is a more common type with high strength, good wear resistance and strong load-bearing capacity. Cast iron square bearing seats have low manufacturing costs and are widely used in light-load and low-speed equipment, such as agricultural machinery, conveyor belts, etc. However, it also has some disadvantages, such as heavy weight and poor corrosion resistance.


Steel plate square bearing seat

The manufacturing cost of steel plate square bearing seats is slightly higher than that of cast iron seats, but they also have better steel and rigidity, and can be suitable for harsh working environments, such as high-speed rotating machinery and equipment and high-intensity loads. At the same time, the steel plate square bearing seat also has anti-corrosion, earthquake resistance, impact resistance and other properties, and can meet the performance needs of the bearing seat in various industries.


Aluminum alloy square bearing seat

The aluminum alloy square bearing seat has the characteristics of lightweight and good thermal conductivity. It has good corrosion resistance and can be used in humid or acid-base environments. At the same time, aluminum alloy square bearing seats are easy to process into various shapes and structures, which can meet the needs of different equipment sizes. However, the load-carrying capacity of aluminum alloy bearing seats is low and is generally only suitable for equipment with smaller loads and machines operating at low speeds.


Plastic square bearing seat

Plastic square bearing seats have low manufacturing cost, are highly lightweight, are not easy to rust, and are also waterproof and soundproof. However, the plastic seat has a low load-bearing capacity and is prone to wear and deformation under heavy loads or high-speed environments.


The selection of square bearing seat material should take into account the equipment working environment, load requirements, performance-price ratio and other factors. Cast iron, steel plate, aluminum alloy, plastic and other materials have their own advantages and disadvantages, and they need to be selected according to the actual situation.


How to install square bearing seat


UCF 640Preparation

1. Carefully read the technical documentation of the bearing seat to understand the structure, performance and installation requirements of the bearing seat.

2. Check whether the required tools and materials are complete, including bolts, nuts, washers, lubricants, etc.

3. Ensure that the installation surface is clean and free of debris to prevent impurities from entering the inside of the bearing seat.


Bearing seat installation

1. Place the bearing seat smoothly on the mounting surface and ensure it fully fits the mounting surface.

2. Use bolts to secure the bearing seat to the installation surface and ensure that the bolt tightening torque meets the requirements.

When installing the bearing seat, ensure that the bearing seat is parallel to the mounting surface 3 to avoid vibration and noise during operation.


Bearing hole dressing

1. Trim the bearing hole to achieve the specified size and geometric accuracy.

2. Use professional tools to trim the bearing hole to ensure that the surface roughness of the hole meets the requirements.

3. Clean the trimmed bearing hole to remove burrs and impurities.


Adjust the gap

1. According to the requirements of the technical documents, adjust the gap between the bearing seat and the bearing hole.

2. After the gap adjustment is completed, you should use tools such as feeler gauges to check to ensure that the gap meets the requirements.

3. For clearances that are too tight or too loose, they should be readjusted to ensure the normal operation of the bearing seat.


Fastening bolts

1. Use appropriate bolts to fasten the bearing housing to the mounting surface

2. When tightening bolts, tighten them diagonally to avoid stress on the bearing seat.

3. After tightening the bolts, check whether the bearing seat is loose and retighten if necessary.


Acceptance inspection

1. Inspect all parts of the bearing seat to ensure there are no obvious defects or problems.

2. Check whether the installation of the bearing seat is firm and reliable to prevent loosening or falling off during operation.

3. Check the lubrication maintenance of the bearing seat to ensure that the lubricant is sufficient and there is no leakage.

4. Check the operation monitoring of the bearing seat to ensure that sensors and other equipment are working properly.

5. If any problems are found, they should be dealt with immediately and re-acceptance inspected to ensure that the quality and performance of the bearing seat meet the requirements.


How to disassemble square bearing seat


1. Remove the fastening screws on the bearing seat. If there are multiple screws on the bearing housing, they will all need to be removed.


2. Use a rubber hammer to gently hit the side of the bearing seat to loosen it. If the bearing seat is relatively tight, you can use a hammer and wooden board combination to tap it.


3. Install a screw on each end of the bearing seat and fix them with nuts. Then, gently rotate the screw to apply force evenly to remove the bearing seat from the shaft.


4. If the bearing seat is very tight, you can use a special bearing seat remover to remove it. Insert the two claws of the puller into the bearing housing and secure them with nuts. Turn the nut so that the claws apply force evenly and remove the bearing housing from the shaft.


It should be noted that before disassembling the bearing seat, the bearing seat and the screws on the bearing seat need to be cleaned. At the same time, be careful not to damage the bearings and bearing seats when disassembling, so as not to affect the normal operation of the machine.
