Structure Characteristics and Applications
Bronze Bearings is based on the copper alloy. It offers technically and economically favorable bearings solutions. It is of high load capability, low weight and good corrosion resistance. Bronze Bearings can offer different types of bronze alloys according to the required life time, service etc. The tolerance is much tighter than wrapped bronze bushes. This kind of products are widely used in machine-tool, agricultural machinery, crane electro motor, spring pin, steering shaft and transmission, etc. We can use different copper alloy material as per customer’s requirements.
Our Cast Bronze Bushings are machined from continuous cast bronze CuSn6Pb6Zn3 for superior quality and performance. The continuous casting process assures a uniform bronze structure throughout the bearing, free from porosity and hard particle inclusions commonly found in other cast processes.

Cast bronze bushing grease groove:
cast bronze bushing is a very key part of the copper castings in cone crusher. Its role is: a, reduce the sliding friction of equipment in operation, reduce power loss; b, greatly increase the wear-resistant parts of cone crusher. Service life, reduce maintenance and maintenance costs, strive for higher equipment utilization rate; C. Effective protection of steel parts in contact with them from wear, when copper parts wear easily replaced. The upper circular plate is installed at the lower top of the main shaft of the cone crusher and above the middle friction disc. The pressure is very large, and his material and size requirements are relatively high. Especially the clearance between him and the middle friction disc is the most important technical difficulty. Because of the errors in manufacturing and installation, it is easy to cause malignant equipment accidents such as bronze bushing cracks or even comminuted fracture or excessive friction resistance in operation. The burning of tiles occurs in the equipment. Therefore, the key to the normal operation of the equipment is to select the cast bronze bushing with guaranteed material and processing size. The wear frequency of cast bronze bushing is higher.

Bronze Bushings Assembly
Also known as the bronze bushings, the bronze bushings is used in sliding and rotating machinery to reduce friction while driving thrust and supporting fixation. The bronze bushings needs oil to lubricate the bearing. Bronze bushings is a variety of brass alloy production for mechanical parts lubrication. Self – lubricating bronze bushings, self lubrication is required. Graphite bronze bushings no need for oil lubrication. Bronze bushing can be used on a variety of large, heavy machinery, is an important component of machinery.
- Housing: Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment
- Shaft: Chamfer 5 mm x 15°, for easy insertion of the shaft
- VIIPLUS advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.
- Freeze fitting is suitable for diameter > 130mm, dry ice or liquid nitrogen can be used.
