Centrifugal Fan Bearing 22312

Centrifugal Fan Bearing 22312, also known as oil-bath bearing 22312, is an important component that helps support motors and centrifugal fans. The main function of this device is to reduce the temperature generated during operation. Let’s learn more details about this centrifugal fan bearing with Thanh Thai Motor!

Overall design of Centrifugal Fan Bearing 22312

The centrifugal blower bearing is designed with a cast iron housing, enhancing durability and corrosion resistance. Solid shafts connected at both ends of the bearing ensure stability and reduce friction during operation. This component is crucial in industrial air blowers, contributing to improved efficiency and extended equipment lifespan.

Internal structure of Centrifugal Fan Bearing 22312

Centrifugal Fan Bearing 22312 features a compact mechanical structure that delivers extremely high transmission efficiency. The main parts include:

• Bearing housing: Encloses the exterior, creates a lubricating oil chamber, and absolutely protects internal details from dust and moisture.
• Bearing shaft (1040mm long): Precisely machined, extending from one end to the other to ensure good dynamic balance and system stability.
• Bearings (Rolling bearings): Uses high-load-capacity bearings to help reduce friction, withstand radial and axial loads, thereby enhancing working efficiency.

Technical specifications of Centrifugal Fan Bearing 22312

Functions and applications of Centrifugal Fan Bearing 22312

Bearing 22312 is typically applied to air blower systems with a capacity of over 3.7kW. This device acts as an intermediate bridge for indirect transmission (via belt) or direct transmission (via coupling) between the motor and the fan blades.

Thanks to the bearing, the fan can operate flexibly, isolating heat sources from the motor without being restricted by installation location. When the motor rotates, the force transmitted to the bearing shaft makes the centrifugal fan blades rotate accordingly, generating a large air volume for ventilation, cooling, dust extraction, or exhaust gas suction for industrial workshops.

User guide for Centrifugal Fan Bearing 22312

To use Centrifugal Fan Bearing 22312 to achieve the highest performance and longevity, technicians should note:

• Compatibility: Ensure the bearing is compatible with the motor and fan pulley/coupling. Especially, the shaft journal diameter (55mm) must fit absolutely.
• Concentric alignment: Ensure the installation surface for the motor, bearing, and fan base is flat. Precisely adjust concentricity to avoid vibration and shaft breakage when running at high RPM.
• Maintenance and lubrication: As it is an oil-bath bearing type, regularly check the oil level sight glass. Fill with oil up to the specified level mark before turning on the power for operation.
