Product Description

Graphite plug C86300 H7 bronze sleeve bushings are designed with self-lubrication properties that ensure smooth and reliable operation with minimal maintenance. These bushings are constructed from a high-quality bronze alloy (C86300) that offers excellent wear resistance and durability.

The graphite plugs integrated into the bushings provide a unique self-lubricating mechanism. As the bushing rotates or slides within its mating component, the graphite releases lubricating particles that coat the contact surfaces, reducing friction and wear. This self-lubricating feature eliminates the need for external lubricants, significantly simplifying maintenance requirements.

The H7 tolerance grade ensures precise fit and alignment, further enhancing the performance and durability of the bushings. The combination of C86300 bronze alloy, graphite plugs, and H7 tolerance grade makes these bushings ideal for a wide range of applications, including machinery, automotive, and heavy-duty equipment.

In summary, graphite plug C86300 H7 bronze sleeve bushings with self-lubrication properties offer superior wear resistance, durability, and low-maintenance requirements, making them a reliable choice for demanding applications.

C86300 PHOSPHOROUS BRONZE BUSHINGS SOLID BRONZE LUBRICATION | VSB-50

VSB-50 Solid Bronze Metallic Self-lubricating Bearings Cast Bronze Bearing with Graphite Plugs

MATERIAL:CuZn25AI5Mn4Fe3

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℃

Strusture

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.
