6208 Deep Groove Ball Bearing 40*80*18 - China Factory Suppliers for Motors and Home Appliances

An inner ring, an outer ring, a steel ball, a cage (usually stamped steel or nylon) and a dust cover/seal ring (optional) are combined into a bearing. It is compact and easy to install.

It mainly bears radial loads and can also bear certain axial loads (bidirectional), but the axial load capacity is lower than the radial load capacity. It has high dynamic and static load capacity and is suitable for medium load scenarios.

Due to the low friction resistance, it is suitable for high-speed operation (high speed can be achieved under grease lubrication or oil lubrication).

The rolling element and the raceway are in point contact, with low friction, smooth operation and low noise, suitable for precision equipment.

Open (no seal), with dust cover (ZZ/2Z) or rubber seal (RS/2RS), can be selected according to dust and water requirements.

household appliances, industrial motors, etc.

gearboxes, wheels (some models), water pumps, etc.

pumps, fans, gearboxes, conveyor belts, etc.

washing machines, vacuum cleaners, power tools, etc.

agricultural equipment, textile machinery and other low to medium load rotating parts.

Avoid direct impact on the bearing, use special tools or apply force evenly. Ensure that the tolerances of the shaft and the bearing seat meet the standard (such as H7/g6).

Select grease (such as lithium grease) or lubricating oil according to the working conditions, and replenish or replace them regularly. High temperature resistant lubricants are required in high temperature or high speed environments.

Avoid overloading or excessive axial load, otherwise it will shorten the life. The speed must not exceed the bearing limit (refer to the manufacturer's manual).

It is recommended to use sealed bearings (such as 2RS) in dusty and humid environments and clean them regularly.

Check whether the bearing has abnormal noise, vibration or abnormal temperature rise (usually the operating temperature should be <80℃).

Generally, grease-lubricated bearings need to be relubricated after 2000~8000 hours of operation.

Replace when there is severe wear, rust, cage deformation or excessive clearance.

It may be due to insufficient lubrication, contamination or damage, and needs to be cleaned or replaced.

Check the lubrication status, alignment or overload.

Confirm whether the installation is correct and eliminate shaft bending or improper fit.
