Centrifugal fan bearing 6312

Centrifugal fan bearing 6312 is widely used in industry. Bearing 6312 is responsible for connecting the motor and the centrifugal fan. The bearing rotates in the same direction as the motor and drives the centrifugal fan to rotate.

General design of Centrifugal Fan Bearing 6312

The centrifugal fan bearing, also known as an oil-bath bearing, features a sturdy cast iron housing with a continuous drive shaft running through both ends of the bearing housing.

What is inside Centrifugal Fan Bearing 6312?

Centrifugal fan bearing 6312 is designed to support the fan shaft, ensuring stable rotation, reducing friction, and extending the lifespan of the entire system. Inside the bearing housing, it consists of the following main components:

• Bearing housing: Cast from heavy-duty cast iron or steel, featuring high rigidity to fix internal components and withstand vibrations during fan operation.
• Bearing (6312 ball bearing): The most critical component, helping the shaft rotate smoothly, reducing friction, and bearing radial loads as well as a portion of axial loads. This allows the fan to operate smoothly and minimizes wear.
• Bearing shaft: The shaft that transmits motion from the motor to the fan blades via a coupling or pulley. The shaft is precisely machined to ensure concentricity, allowing the fan to rotate stably and minimizing vibration.
• Oil and dust seals: Responsible for retaining lubricating oil or grease inside while preventing dust, water, and impurities from entering the bearing, helping to extend the lifespan of the bearing.
• End cap and retaining ring: Used to fix the bearing and shaft in the correct position, preventing shifting when the fan operates continuously at high speed.
• Lubricating grease or oil: Contained inside the bearing housing to lubricate the bearing, reduce temperature, and minimize wear throughout operation.

Application functions of Centrifugal Fan Bearing 6312

The air blower bearing above 3.7kW acts as an intermediary component, connecting the motor and the centrifugal fan. When the motor rotates, the bearing also rotates accordingly. Consequently, the centrifugal fan cools the motor as well as the surrounding environment.

• Industrial dust collection fan systems: Supports the fan shaft, helping the fan operate continuously and reducing vibration during the suction of wood, cement, metal dust, or production dust.
• Exhaust gas treatment systems: Installed on exhaust fans handling hot, toxic, and exhaust gases in factories, helping the shaft rotate stably when working with heavy loads and long operating hours.
• Factory ventilation systems: Used for supply and exhaust centrifugal fans in factories, warehouses, and commercial centers, ensuring smooth and durable fan operation.
• Indirect drive centrifugal fans: Combined with pulleys and V-belts to transmit motion from the motor to the fan blades while protecting the motor when working in high-temperature or dusty environments.
• Rotating shaft drive equipment: Besides centrifugal fans, bearing 6312 is also applied in conveyors, screw conveyors, crushers, and mechanical equipment with rotating shafts requiring high stability.

Instructions for using Centrifugal Fan Bearing 6312

To use the centrifugal fan bearing, note the following:

• Check the dimensions of the motor and centrifugal fan, and choose a bearing of suitable size.
• Select the installation location and connect the motor and centrifugal fan together via the bearing.
• Supply power to the motor and start operation.
