Factory Price Crusher Machine Spare Parts Tin Bronze Eccentric Bushing

Product description​ :

Copper bushing is a part of mechanical equipment, which is mainly used in mining machinery and equipment, and it is widely used. In the application process of mechanical equipment, copper bushing is an indispensable part.

This product is based on the excellent electrolytic copper, and mixed with tin ingot and lead ingot according to the national standard proportion to form the high wear-resistant self-lubricating copper alloy material. Under the condition of lacking lubricant and using water quality lubricant, it shows excellent sliding and self-lubricating performance. 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.

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.
