Plain CuSn5Pb5Zn5 Solid Lubricant Bearings are renowned for their wear resistance, offering exceptional durability and performance. These bearings are crafted from a unique CuSn5Pb5Zn5 alloy, which incorporates a solid lubricant to significantly reduce friction and wear.
The wear resistance of these bearings stems from the synergistic combination of their alloy composition and the solid lubricant. The CuSn5Pb5Zn5 alloy exhibits excellent lubrication properties and mechanical strength, while the solid lubricant continuously releases lubricating substances during operation, creating a lubricating film that minimizes metal-to-metal contact and subsequently wear.
Moreover, Plain CuSn5Pb5Zn5 Solid Lubricant Bearings boast high load-bearing capacity and impressive impact resistance, enabling them to thrive in various challenging industrial environments. Wh under high loads, high speeds, or elevated temperatures, these bearings maintain stable performance, ensuring the smooth operation of machinery and equipment.
Due to their remarkable wear resistance and reliability, Plain CuSn5Pb5Zn5 Solid Lubricant Bearings are widely used in numerous industrial applications. They not only enhance the durability and reliability of equipment but also contribute to reducing maintenance costs and downtime, thereby generating significant economic benefits for businesses.

Advantages of oil-free self-lubricating bearings
1. No oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used in no maintenance or less maintenance;
2. Good wear resistance, small friction coefficient and long service life;
3. There is an appropriate amount of elastoplastic, can distribute the stress on a wider contact surface, improve the bearing capacity;
4. The static and dynamic friction coefficient is similar, which can eliminate the creep at low speed, so as to ensure the working accuracy of the machine;
5. It can reduce the vibration, noise and pollution of machinery;
6. Transfer film can be formed in the operation process to protect the grinding shaft, without shaft biting phenomenon;
7. For grinding shaft hardness requirements are low, the shaft without conditioning can be used, reduce the processing difficulty of related parts;
8. Thin wall structure, light weight;
9. Bushing can be used in corrosive media.
The arrangement of these solid lubricant deposits is adapted to the intended sliding movement. They serve, on the one hand, to deliver the lubricant to the sliding partner and, on the other hand, to absorb dirt particles in the bearing.
The standard material for plain bearings with solid lubricant For special parts, however, other copper alloys are also possible on request, e.g.
The solid lubricant used, based on graphite and additives, is ideally suited for general use and normal atmospheres.
For applications in which the bearings are exposed to water or seawater, there is a special solid lubricant based on MoS2 and as well as other additives.
