C86300 manganese bronze sleeve bushings are specifically designed to provide reliable and long-lasting performance in medium load applications. Their self-lubricating properties ensure smooth operation with minimal friction and wear, even under demanding conditions.
These bushings are manufactured from C86300 manganese bronze alloy, which is known for its excellent strength, wear resistance, and corrosion resistance. The alloy's composition allows it to withstand moderate to heavy loads while maintaining dimensional stability.
The self-lubricating feature of these bushings is achieved through the incorporation of lubricant-filled pores or particles within the bronze matrix. As the bushing rotates or slides, the lubricant is released to coat the contact surfaces, reducing friction and wear. This eliminates the need for external lubricants and reduces maintenance requirements.
The bushings are suitable for a wide range of medium load applications, including machinery, automotive components, and heavy-duty equipment. They can be customized to fit specific requirements, including different sizes, shapes, and mounting configurations.
In summary, C86300 manganese bronze sleeve bushings with self-lubricating properties offer reliable and long-lasting performance in medium load applications. Their superior material properties and self-lubricating feature ensure smooth operation and reduced maintenance requirements.

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.
