Casting Bronze Bearing


Lubricating Parts Material


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.

We specialize in manufacturing self-lubricating bearings



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.
