BRONZE BEARINGS

          Bronze bushings, bronze bearings and bronze continuous cast bars are manufactured by SANBURG BEARING INT'L LTD in Muncie, Indiana. Our foundry provides our customers with the highest quality bronze bars and tubes.

          Bronze is a copper alloy whose strength and lubricity make it well-suited for use as a bearing material. Manufacturers use bronze bearings to support spinning shafts in machinery. Hardened steel ball bearings and needle bearings have replaced bronze in applications that are subjected to high speed and heavy loading, but bronze bearings are still common in other applications because of their lower cost.

           These bearings are a lot tighter tolerance, but still very smooth movement. They are oil impregnated, so as there is movement, it creates a layer of lubricant of sorts. Another big benefit is that they are press fit, so no more set screws, and the alignment is much, much better. So the end assembly will be much easier for the kit form. Another benefit is that the pieces that they fit into can be significantly smaller, so that lowers the weight and material usage as well as potentially making the mechanism that much more compact.
We are a long time certified supplier to original equipment manufacturers (OEM’s) in the hydraulic, pump, diesel engine and compressor industries. We specialize in precision-machined bronze parts such as valve guides, hydraulic packing glands, thrust washers, seal rings, power transmission parts, sleeves and gear blanks.

           Continuous cast bar stock and finished parts materials commonly include: C93200 (SAE660), C93700 (SAE64), C95400 (Aluminum Bronze), C86300 (Manganese Bronze), C90300 "G", C90500 "Gun Metal", C91600 & C91700 "Gear Bronze", C83600 "Red Brass". We are particularly competitive on special shapes and special alloys both in producing cast bronze parts or continuous cast bars and tubes.
