Self-Lube Graphite Plugged Bronze Bushings are sliding components that incorporate graphite plugs for self-lubrication purposes. These bushings, also known as slide plates, are designed to operate without the need for external oil or lubrication, as the graphite plugs provide the necessary lubrication during operation. The bronze material, combined with the graphite plugs, offers excellent wear resistance and low friction, making these bushings suitable for a wide range of applications where oil-free sliding is desired.

Essential advantages of maintenance-free plain bearings with lubricating plugs are:
Suitable for corrosive environments
High load capacity
Maintenance-free
Suitable for impact loads and vibrations
Suitable for high temperatures
Excellent performance under high-load, Iow-speed circumstances
The VIIPLUS bronze graphite bushings are made of cast high-strength copper as the matrix, which functions as Ioad bearers.Besides, BRONZE GRAPHITE BUSHINGS SERIES use specially formulated graphite as Iubricant, ensuing excellent self-lubrication. Combining the advantages of both the matrix and Lubricant, BRONZE GRAPHITE BUSHINGS are capable of exert their wonderfuI performance in circumstances with high load and low speed
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-50P Sliding Block 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.
