Product Description

Oilless CuSn6-6-3 Self Lubricating Bronze Bearings Low Friction


Sintered Bronze Flange Bushing Bearing

Bronze sleeve bushings or bronze bearings are hard and strong, as opposed to brass bushings, which are softer and more easily deform. Thus, bronze bushings have longer lifespans than brass bushing sleeves. They resist shock and impact, wear and corrosion.They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear.


Bunting cast bronze lead-free bearings are machined from continuous cast CuSn6-6-3 CCVK 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. Our Bronze bearings have been independently tested and proven to be superior to other cast lead free materials.
