Product Description
| Bronze Bushings - Detailed Technical Specifications | ||||
| Grade / UNS | Common Name | Fabrication Method | Key Characteristics | Typical Applications |
| Grade / UNS | SAE 660 / High-Leaded Tin Bronze | Continuous Cast / Centrifugal Cast | General-purpose bearing alloy; good anti-frictional properties; moderate load capacity; excellent machinability; contains lead for embeddability | General bushings, sleeve bearings, washers, low-to-medium load sliding components |
| C93200 | Aluminum Bronze | Continuous Cast / Centrifugal Cast | Non-lead "green" alloy; high strength and hardness; excellent abrasion and corrosion resistance; retains properties at elevated temperatures; requires hardened steel shafts and lubrication | Heavy-load bearings, earth-moving equipment, roll neck bearings, machine tool bearings, marine hardware |
| C95400 | Sintered Bronze (Powdered Metal) | Powder Metallurgy | Oil-impregnated, self-lubricating; porous structure for oil retention; maintenance-free operation | Standard off-the-shelf sleeve bearings, flange bearings, moderate-speed applications |
| SAE 841 | Phosphor Bronze | Wrought / Machined | High wear resistance; high compressive strength; excellent anti-galling properties; low coefficient of friction | Articulation joints, heavy-duty wear sleeves, construction equipment linkages |
| Phosphor Bronze (CuSn8P) | High-Leaded Tin Bronze | Centrifugal Cast | High lead content (9-11%) for superior anti-seize properties; acts as "sacrificial fuse" to protect mating components | Cone crusher eccentric bushings, heavy industrial wear components |
| C93700 | High-Leaded Tin Bronze | Centrifugal Cast | High lead content (9-11%) for superior anti-seize properties; acts as "sacrificial fuse" to protect mating components | Cone crusher eccentric bushings, heavy industrial wear components |
