JFBB Metric Self-lubricating Oilless Graphite Flanged Bearings Bushings

JFBB self-lubricating bearings are oil-free graphite bearings made by embedding solid lubricants (usually graphite or MoS₂) in a high-strength metal matrix. This design ensures that the bearing can continuously provide lubrication during use without the need for additional oil or grease lubrication. The product is designed with metric specifications, suitable for standardized applications, and is widely used in bearing seats of various mechanical equipment.

Key Features
Self-lubricating performance
By embedding solid lubricants, this bearing can achieve continuous lubrication throughout its life cycle without the need for external lubricating media.

It can still maintain excellent operating performance in oil-free or low-oil environments.

High temperature resistance
Graphite lubricating materials are extremely stable under high temperature conditions and can work normally in environments of 250°C or even higher.

High load carrying capacity
The metal matrix provides extremely high mechanical strength and is suitable for heavy-load conditions.

Wear resistance
The ingenious combination of embedded graphite lubricating materials and metal matrix gives it excellent wear resistance and extends the service life of equipment.

Environmentally friendly
No need to use traditional lubricants, reducing lubricant consumption and potential leakage risks.

Application scenarios
JFBB self-lubricating bearings are widely used in the following fields due to their excellent performance:

Automotive industry
Used in high-temperature or high-load components such as engines, brake systems, and transmissions.

Metallurgical equipment
Including continuous casting machines, rolling mills, and other equipment in high-temperature environments.

Engineering machinery
Equipment such as excavators and cranes that need to withstand high loads and long-term operation.

Food processing equipment
Work in an environment where pollution is not allowed, replacing traditional oil-lubricated bearings.

Marine industry
Used in humid or underwater environments to reduce the impact of lubricant loss on the environment.

Product specifications and design
JFBB bearings are flanged, which makes them easier to install and fix. The product is manufactured according to international standard metric sizes and is compatible with a variety of mechanical equipment. The flange design can also provide additional axial positioning functions in certain applications to improve installation reliability.

Maintenance and Care
Although JFBB bearings are self-lubricating products, the following points should still be noted in actual use to extend the service life:

Regularly clean the bearings and their surroundings to prevent impurities from entering.

Ensure alignment during installation to avoid additional friction.

Check the equipment load to ensure that the maximum load capacity of the bearing design is not exceeded.
