Insert bearings:Application,Types and disadvantages

Insert bearings are a type of bearing that is used to support rotating shafts and house the bearing components within a housing. They are also known as housed bearings and are often used when replacing a bearing in an existing housing or when permanent mounting is required. Insert bearings are available in two main types: radial insert bearings and angular contact insert bearings.

Radial insert bearings are the most common type of insert bearing, and are typically used for moderate radial loads at relatively low speeds. These bearings have an inner ring with a cylindrical outside diameter and a convex inner surface that is seated in the housing bore. An outer ring with a cylindrical and a concave inner surface is then snapped into the housing bore and placed over the inner ring.

The inner and outer rings have deep grooves that fit together to form a ball or roller bearing that is pre-lubricated and sealed. Angular contact insert bearings are used for higher radial loads and speeds, and are designed to support the combined loads of radial and axial forces. These bearings have an inner ring with a cylindrical outside diameter and a conical inner surface that is seated in the housing bore. An outer ring with a cylindrical and a concave inner surface is then snapped into the housing bore and placed over the inner ring.

The inner and outer rings also have deep grooves that fit together to form a ball or roller bearing that is pre-lubricated and sealed. Insert bearings are used in a wide range of applications, from industrial equipment to consumer goods. They are often used in the automotive and agricultural industries, as well as in the aerospace and medical industries. Insert bearings are typically used to support rotating shafts and reduce friction and wear, as well as to improve the performance of the machine or device.

Benefits and drawbacks of insert bearings

Benefits:

1. Insert bearings have a low-friction design that reduces the need for frequent lubrication, which can help reduce operating costs.

2. They are easy to install and require little maintenance, making them a cost-effective option for many applications.

3. Insert bearings can accommodate high radial loads, making them a good choice for applications that require heavy loads.

4. They offer superior sealing qualities to protect against dust and other contaminants.

Drawbacks:

1. Insert bearings can be expensive compared to other bearing types due to their specialized design.

2. They are not suitable for applications that require extreme temperatures or frequent shock loads.

3. Insert bearings are not as durable as other bearing types, so they may need to be replaced more frequently.

Uses of Insert bearings

Insert bearings are used in a variety of industrial applications, such as conveyor rollers, agricultural equipment, pumps, and electric motors. They are also used in automotive components, such as wheel hubs, transmissions, and power steering systems. Insert bearings are ideal for applications where the bearing is exposed to large amounts of shock and vibration, as they are constructed with a solid inner and outer ring, as well as a bearing insert that is designed to absorb shock.

Structure of Insert bearings

Insert bearings typically consist of two components, an outer or housing race and an inner or shaft race, with a spherical bearing element pre-assembled between them. The bearing elements are usually made of steel, but can also be made of a polymer material. The bearing elements may be pressed into the housing and/or shaft race, or may be secured with a snap ring or set screw. The inner and outer races are usually made of steel, but may also be made of a polymer material. Insert bearings are typically used in agricultural, automotive, and industrial applications.

Types of Insert bearings

1. Radial Insert Ball Bearings: These bearings are used to support rotating shafts and are often found in applications such as pumps and electric motors.

2. Angular Contact Insert Ball Bearings: These bearings are designed with a contact angle to accommodate axial loads in both directions.

3. Thrust Insert Ball Bearings: These bearings are typically used in applications such as compressors, pumps and turbines.

4. Groove Ball Insert Bearings: These bearings are used to support rotating shafts and are commonly found in agricultural machinery, fans and pumps.

5. Spherical Roller Insert Bearings: These bearings feature a spherical roller design and are often used in applications such as conveyors and paper machines.

6. Cylindrical Roller Insert Bearings: These bearings are designed to support radial loads and are commonly used in applications such as paper machines and conveyors.

The bottom line for insert bearings is that they are a cost-effective and reliable solution for many applications. They are easy to install and maintain, and can be designed for a variety of applications. They offer a great deal of flexibility, allowing for customization to fit the individual needs of each application.
