Bronze bushings play a huge role in reducing friction.
Types of Bronze Bushings, crankshaft bearing
In the realm of mechanical press machines, the demand for reliable and efficient bearing solutions is paramount. Heavy-duty crankshafts, a critical component in these machines, face significant challenges due to high impact and speed. A key concern has been the warming of CuSn12 bronze bearings during operation. This blog post explores how integrating solid lubricants like graphite into CuSn12 bronze bearings can effectively address these issues, enhancing performance and longevity in mechanical press machines.

Addressing Warming Causes and Solutions
In addition to using graphite-impregnated bearings, it’s essential to ensure the correct type and amount of lubricant is used. In some cases, upgrading the lubricant or increasing its quantity can provide immediate relief from warming issues. Additionally, installing heat exchangers or radiators can be an effective method to dissipate heat from the bearing surface, further preventing overheating.
Understanding the Challenge: CuSn12 Bearings and Warming Issues
Choosing the Right Bronze Bushing for Your Needs
CuSn12, a high-quality bronze material, is widely used for bearings in mechanical presses due to its excellent wear resistance and mechanical properties. However, one persistent issue with CuSn12 bearings is their tendency to warm up during high-speed operations. This warming can lead to reduced efficiency, increased wear and tear, and potentially costly downtimes.
The Graphite Solution: Enhanced Self-Lubrication, Bronze Bearings & Bronze Sleeve Bushings
The integration of graphite as a solid lubricant in CuSn12 bearings presents a transformative solution. Graphite is renowned for its self-lubricating properties, which can significantly reduce friction between the bronze bushing and the crankshaft. This reduction in friction directly addresses the warming issue by minimizing heat generation during operation.
Improved Lubrication Conditions
The self-lubricating nature of graphite ensures consistent lubrication, even under high-load conditions. This continuous lubrication is crucial in preventing the bronze sleeve from overheating and reduces the reliance on external lubricants.
Enhanced Heat Conductivity
CuSn12 alloy, combined with graphite, improves heat dissipation. The efficient transfer of heat away from the bearing surface helps in maintaining optimal operating temperatures.
Durability and Impact Resistance
CuSn12 material, known for its high tensile strength, coupled with graphite’s lubricating properties, makes these bearings highly durable and resistant to the impacts and stresses typical in mechanical press operations.
