Rolling Machines Casting Bronze Copper Bushings With Oil Groove
Product description
The machining and casting of bronze bushing provides a technically and economically advantageous bearing solution. High bearing capacity, light weight and good corrosion resistance. We can provide different types of bronze alloy according to the service life. Its tolerance is much higher than that of bronze shaft sleeve. Our precision bronze shaft sleeve is made of various materials.
We can make the oil grooves according to customer’s requirements, or make the bronze bushing according to the drawings from our customers.
