Mining Hydraulic Crusher Machine Spare Parts Eccentric Bronze Bushing And Socket Liner
Product description :
Tapered copper bushing, high lead tin bronze bushing, wear-resistant bowl type bushing, environmental friendly recyclable copper bushing. This product is based on excellent electrolytic copper, matching tin ingot and lead ingot according to the proportion of national standard. Under the condition of lacking lubricant and using water quality lubricant, it shows sliding and self-lubricating properties. Under the load of high-speed rotation and swing motion, the impact load resistance is up to 50MPa, showing excellent flexibility, which is the first choice of high-speed running mechanical equipment.
The copper bush of crusher plays the role of bearing, which belongs to the sliding bearing category. It is a bearing working under the sliding friction. The relative shaft is rotating, and generally needs to be assisted by a lubrication system. Stable, reliable and noiseless operation. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has certain vibration absorption capacity, such as lubrication, heat dissipation, friction reduction and life extension. Copper sleeve is mainly used in machinery, printing and dyeing, papermaking, chemical industry, aerospace, coal, petroleum, automobile, engineering machinery, gold treatment and other industries.

Instructions for inquiry:
1. Drawing: you only need to provide one of the drawing, drawing number, sketch and sample. (these are the premise of our service to you, and also the important standard to facilitate your acceptance of the workpiece after we do it well, so you must provide.)
2. Quantity: you need to customize the number of artifacts. (the more quantity, the more favorable price
3. Material: the material requirements of the workpiece; (is it a national standard or an enterprise standard or an export American Standard, please indicate that these will affect the price to a great extent!)
4.Duration: This is also an important information. If you need it urgently, it will increase the manufacturing cost. Generally, the manufacturing cycle of castings is 8 days.
