We stock over 650 sizes of R-Con® (CDA 932 or SAE 660) cast bronze sleeve bearings on our shelves. These bearings are machined from continuous cast bronze to offer a consistent composition throughout the bearing. This process also eliminates the chance for porosity and other flaws found in similar casting methods.

R-Con® bearings can be taken from the shelf and grooved within 24 to 48 hours depending on quantity and availability.
