Completely Finished Bronze
A better process: A Better Product
Magnolia produces completely finished bronze bushings, sleeve bearings, flanged bushings, wear parts, rings, blanks, and custom shapes machined to your specifications. From one replacement component to repeat production quantities, we provide ready-to-install bronze parts that reduce the additional machining required at your facility.
Our steel-cast and continuous-cast bronze processes provide consistent material for industrial bearing and wear applications. We machine oil grooves, keyways, drilling, radii, windows, pockets, split configurations, matched halves, and other required features based on your print or finished dimensions.
Ready-to-use parts machined to your blueprints
Magnolia bronze bearings are all either cast continuously or cast in steel. No sand is used in manufacturing. This entirely eliminates patterns and core boxes with savings passed on to you. Because all your machining can be done by Magnolia, you are saved additional machine time in your own plant, resulting in lower costs. All castings are machined. No bronze is shipped in an “as cast” state.
Magnolia steel-cast bronze wears much longer and is far tougher and stronger than the best sand cast product. Being absolutely free of any hidden sand particles insures a longer life for your shaft.
The Magnolia crystal control method of centrifugal casting allows for a uniform or “isotropic” crystal structure, unlike that found in sand cast metals, while raising physical characteristics far above the requirements for similar formula sand castings.
Flanged Bronze Bushings and Bearings
Magnolia machines flanged bronze bushings, bronze flange bearings, and flanged sleeve bearings for applications that need both a bearing surface and an integral flange for axial location or thrust support. A flanged bushing combines a cylindrical sleeve with a machined flange, which can help position the part while providing a wear surface in the assembly.
We can manufacture bronze flange components to your blueprint, including finished inside diameter, outside diameter, flange diameter, length, oil grooves, drilling, keyways, and other required machining features. Flange components are available through 34 inches outside diameter of flange.

A better bronze: a better product CDA 936 Superior to CDA 932
Tests conducted in both a national laboratory and a major university confirm Magnolia CDA 936 consistenly outperforms CDA 932 (SAE 600) under the most difficult conditions in test after test.
CDA 936: Better because
- Higher lead content gives better lubricating properties and provides better co-efficient of friction. Bearings run cooler, last longer.
- One and a half times as resistant to pounding.
- Acid resisting to sulphite fluids due to lower zinc. CDA 936 can be used in areas where CDA 932 would corrode.
The best Bronze: Tested & Proven
Laboratory Tests Prove it!
Tests conducted by a national laboratory verify that Magnolia CDA 936 consistently out performs CDA 932 (SAE 660) under the most difficult conditions in test after test. The bearings were run with inadequate lubrication until temperatures exceeded 400ºF. Under these severe conditions, in some instances teh CDA 932 wore out three times faster than CDA 936. In no test did CDA 932 out perform CDA 936.
Newly completed tests by a major university also prove that Magnolia’s CDA 936 alloy has a significantly higher failure resistance than CDA 932. Despite extreme circumstances, operating without lubrication, CDA 936 ran an average of 78% longer than CDA 932, and with none of the incidents of severe shaft scoring found among the CDA 932 tests.
Finished Parts or Semi-Finished Bearings?
Choose completely finished bronze when you need a component machined to its final dimensions and ready for installation. This option is well suited for customers who want Magnolia to complete the turning, drilling, grooving, keyways, split configurations, and other specified features.
Choose semi-finished bronze bushings and bearings when your shop plans to complete final machining. Semi-finished parts are supplied with machining allowance above the requested finished size, giving your team material to clean up and finish to the final dimensions.
Magnolia Guarantees No Rejects
Magnolia Bronzes are guaranteed to be free from all defects. In Magnolia Bronze there are no blow-holes, no sand spots, no segregated elements, no flaws… no under-surface faults of any kind to cause rejection.
In accordance with industry practice, guarantee is limited to free placement of material returned. But why just “hope” to get a good casting? Magnolia’s quality control procedure has resulted in returns of less than 1/2 of 1% of all bronze shipped over the last 10 years. This standard of excellence combined with our special alloy and our unique casting process assures you of the best possible value in bearing bronze.
