What is Insert Bearings ?

Insert bearings are based on sealed deep groove ball bearings in 62 and 63 series, but they have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft. The outer ring has the intercepted surface which can adjust the center with the concave spherical bearing automatically.

What are advantages of insert bearings ?

01/

Easy to install

Intert bearings can be easily replaced when needed, which can save maintenance time and costs and reduce installation time and workload

02/

Long service life

The design of UCX bearing allows it to adjust to misalignments and provide uniform load distribution, which can prevent premature failure due to stress concentration.

Types of Insert bearings

1.Triple-Sealed Ball Bearings

The main function of the Triple-Sealed bearing is to prevent impurities such as dust and sewage from entering the interior of the bearing, prevent bearing failures caused by this, and extend the bearing life. The design of a Triple-Sealed can effectively isolate external dust and sewage, while preventing lubricating oil leakage, ensuring correct lubrication of bearings, and reducing noise and vibration.

2. UCX bearing

This kind of bearings are Medium Duty, Set Screw Locking Type with Wide Inner Ring Bearing,alsothey are available in free-spinning design and/or with black oxide finish

3. UK bearing

The UK series bearings have a spherical outer ring. The inner ring is tapered with the shaft (it can be installed directly on the tapered shaft or on the cylindrical shaft using a clamping sleeve). Due to the lubrication hole on the outer ring of the hole, the bearing can be relubricated during operation.

4.SB200 series

SB 200 series ball bearing is self-aligning for standard load capacity,we can Use SB Insert Bearings as replacement bearing for many Pillow Blocks, such as 2-Bolt Flanges, 3-Bolt Flanges, 4-Bolt Flanges, Take up units , etc.... Saving money for replacing the insert bearing instead of replacing the whole unit.

5. SER bearing

The SER insert bearings are fully sealed bearings and have a cylindrical OD with a snap ring.There are 2 sets screws at 120 degrees to allow tightening against the shaft once fitted. They are available in bore sizes ranging from 1/2" through 2-7/16".

6.Ball bearings with setscrew

This kind of bearings feature a set screw locking system which use screws to secure the inner ring to the shaft. This type of shaft locking mechanism is easy to use and does not require a collar. In addition, they are suitable for reversing direction applications.

Material of Insert bearings

Chrome steel

One of the most commonly used materials for bearings is chrome steel. This is due to its perfect combination of strength, durability, and wear resistance. Chrome steel bearings can withstand high temperatures and resist corrosion, so it is an ideal choice for various industrial environments.

Ceramic

Ceramic bearings are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

Stainless steel 304

AISI 304 stainless steel, widely used as corrosion- and heat-resistant steel and also as nonmagnetic steel, is most suitable in corrosive environments where AISI 440C stainless steel can not be used.AISI304 Stainless Steel bearings are particularly useful in industries such as food and beverage processing, medical equipment, and marine applications.

Stainless steel 420

420 stainless steel is a martensitic stainless steel that is recognized for its unique combination of strength, corrosion resistance, and impressive wear resistance.Stainless Steel Ball Bearings are ideal for many industries, including marine and food and washdown areas.

How to maintain insert bearing ？

Keep bearings clean and lubricated

The most important thing to maintain insert bearings is to keep them clean and lubricated. Cleaning the bearings is crucial for the normal operation of the machine.Ensure to remove any dirt or debris that may accumulate on the bearings.After cleaning the bearings, we need to apply appropriate lubricant to maintain their smooth operation.

Inspect the bearings regularly

Regular inspection of insert bearings is crucial for identifying potential problems before they become severe.If any problems (such as wear, corrosion or damage) are found, please replace the bearings immediately. In addition, make sure to inspect the shaft to ensure that it is in good condition and free from any defects that may cause bearing failure.

Correct installation of UC bearings

UC bearings mush be installed correctly to ensure the proper operation of insert bearings.Please follow the manufacturer's recommendations to install the bearings and use the correct tools.Additionally, please ensure proper alignment of the bearings to prevent premature failure.

Use the correct bearing housing

Choosing the correct bearing housing is crucial for the normal operation of the inserted bearing. Make sure to choose the housings that is suitable for your application. The housings should provide appropriate support for the bearings and protect them from contamination. Use the correct installation bolts and ensure that they are tightened according to the manufacturer's specifications.

Components of insert bearings

inner rings

The inner ring of the insert bearing is a component that rotates together with the shaft which it installed on. It has a tapered hole that matches the diameter of the shaft, as well as a fixing screw or eccentric locking ring that fastens it in place.

out rings

The outer ring is the fixed part of the bearing, which is used to accommodate ball bearings. It has a spherical profile that allows for misalignment between the shaft and the housing, that is particularly useful in applications where there may be shaft deflection or uneven loads.

balls

Balls are the core of insert bearings. They have various sizes and materials, such as chromes steel,stainless steel or ceramics, they are designed to handle radial and axial loads while providing smooth rotation.

seals

Seals are used to prevent contaminants from entering the bearings and retain lubricant inside the bearings. They are usually made of rubber or metal and come in various configurations such as single lip, double lip, or Triple-Sealed.

cages

Cage is a part of bearings that keeps the ball bearings evenly spaced and allows them to rotate without touching each other. It's typically made of a synthetic material that's resistant to wear and tear.

Process of insert bearings

Material selection

It is the first step in ensuring that a bearing will perform correctly and meet the operational requirements.

Cutting the steel pipe

The first step in producing ball bearings is cutting the steel pipe. Steel is an essential material for making ball bearings because it is strong and durable. The steel pipe is cut into small pieces known as blanks. These blanks will eventually become the spheres that are the most important part of a ball bearing.

Machining

It includes the processes of lathe and grinding. Lathes are used in the initial processing of the bearings by removing material from the object while grinding machines are used in the finishing process. We have the High precision machines to achieve tight tolerances and measurements which are required in producing quality bearings.

Heat treatment

After machining, the ring is heat-treated to improve its hardness, strength, and wear resistance. This is usually done through a process of quenching and tempering, which involves heating the ring to a high temperature and then rapidly cooling it.

Cleaning the rings

It is very important to clean the rings before assembling, as 1.Prolong the lifespan of the bearing.2.Prevent corrosion.3. Maintain the efficiency of the bearing 4. Reduce the risk of machine failure

Assemble bearings

When the rings are ready, we assemble with steel balls and a cage to form the complete bearing unit. The balls are between the two rings, to create a smooth and friction-free rotation.

Lubrication

Finally, the bearing is lubricated with grease or oil to reduce friction and wear

Testing

After finished bearings, we will do various quality control tests to ensure bearings’ performance and durability. These tests can include measuring vibration, noise, rotation speed, load capacity and so on.

Marking items and brand

When the bearings are tested, we will mark items and brand on the rings, both customers' brand or our CTS brand are ok. We do the brands according to our customers' need.

Compared with traditional insert bearings, our products brings a range of benefits, and it will be a wiser choice to meet your industrial needs.
