High-strength graphite sleeve bearings paired with an H7 pulley bushing assembly offer a unique combination of durability, precision, and efficiency. Graphite, as a material, is known for its excellent wear resistance, self-lubricating properties, and high-temperature stability. These qualities make graphite sleeve bearings particularly suitable for demanding applications that require a high degree of reliability and longevity.
The H7 pulley bushing assembly complements the graphite sleeve bearings by providing a precise fit and ensuring smooth rotation. The H7 tolerance class specifies a relatively tight fit, which helps maintain stability and minimize vibration during operation. The assembly also allows for easy installation and disassembly, facilitating maintenance and repair.
When combined, the high-strength graphite sleeve bearings and H7 pulley bushing assembly create a robust and dependable bearing system. This system is capable of handling heavy loads, high speeds, and frequent starts and stops, making it suitable for a wide range of industrial applications.
Overall, the use of high-strength graphite sleeve bearings paired with an H7 pulley bushing assembly represents a smart choice for those seeking a bearing system that offers both superior performance and long-term reliability.

VSB-50 Solid Bronze Metallic Self-lubricating Bearings
Cast Bronze Bearing with Graphite Plugs
CuZn25AI5Mn4Fe3
VSB-50 Solid Lubricating Bearing is produced by streng thening 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.
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.
