Bronze 863 Round Bar 15" diameter Retail Price

About 863|Sintered bronze, oil-impregnated (SAE 863 specification). Made by compacting bronze powder and sintering it into a porous structure, then vacuum-impregnating with oil. The porosity acts as an oil reservoir — the bearing self-lubricates under load. This is the standard for small, low-speed bearings in motors, appliances, power tools, and office equipment. Not a machining material. Bushings are pressed to net shape from powder and rarely see secondary machining. If they do, use light cuts at low speed to avoid collapsing the porous structure. Compare to C932 (cast bearing bronze, higher load capacity) and SAE 841 (iron-based sintered bearing, higher strength).
