Graphite Plug
Graphite plug is a small cylindrical piece of graphite that is inserted into the surface of a bronze bearing. Graphite is a solid lubricant that reduces friction and wear between the bearing, shaft, or other moving parts.
Product Info
The benefits of graphite plugs include:
- Consistent lubrication throughout the service life of the bearing
- Ability to withstand temperatures up to 750°F (400°C) without melting or degrading
- Resistance to corrosion and chemical attack
- Ability to handle shock loads and vibrations without breaking or cracking
- Reduced maintenance costs and downtime by eliminating the need for frequent lubrication or bearing replacementThey are handy for applications that involve high temperatures, high loads, or corrosive environments where conventional liquid lubricants may not be effective or available. The graphite plugs release lubricating particles when the bearing is in relative motion. The graphite particles form a thin film on the contact surfaces, creating a smooth, slippery layer that minimizes metal-to-metal contact. This reduces the friction coefficient and heat generation, resulting in less wear and longer bearing service life.
Application
Graphite plugs are primarily used in applications that need continual lubrication in hard to reach areas. Graphite is mechanically forced into the holes/grooves under extreme pressure. A film of lubricant is transferred to the shaft as it begins to turn. These bearings offer continuous lubrication over long periods without maintenancel.
