Introducing our maintenance-free graphite plugged bronze bearings for valves, specifically designed for industrial applications requiring high durability and reliability. These bearings feature a unique steel/copper composite bushing that combines the strength of steel with the wear resistance of copper, ensuring long-lasting performance.
The graphite plugs within the bearings provide excellent lubrication and heat dissipation, minimizing friction and wear. This results in smoother operation and reduced maintenance requirements, making them ideal for valves and other rotating equipment in demanding industrial environments.
The steel/copper composite bushing offers superior mechanical properties compared to traditional materials, including higher strength, hardness, and corrosion resistance. This ensures that the bearings can withstand the rigorous demands of heavy-duty applications while maintaining precise fitment and optimal performance.
Our graphite plugged bronze bearings for valves are customized to meet specific application requirements, ensuring a perfect fit and maximum efficiency. Wh you need to replace worn-out bearings or upgrade your equipment with high-performance components, our steel/copper composite bushings are the perfect solution.

Maintenance-free plain bearings with lubricating plugs big size Reasons for Selecting Plug Graphite Self-Lubricating Products
The manufacturing process of sintered components is certified as ecological, because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.Plug graphite bearings 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 maintenance.

Structure Characteristics and Applications
VSB-50 Solid Lubricating Bearing is produced by strengthening brass that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion abitity in air, fresh water and sea water. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. The product is widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.

Characteristics
with Solid Graphite Lubrication. Various material specifications, standard and special shapes are also available
VSB-50 Solid lubricating bearings
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
VSB-50 SOLID LUBRICANT SLIDING BEARINGS material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
