plain bronze bushing are maintenancefree, self-lubricating constructional elements of high reliability and performance. The material has microscopic pores which are filled with liquid (approx. 30 percent by volume oil) or solid (MOS 2) lubricant, depending on the requirements. Main feature of sintered bearings: High frictional speed at low load The bearings – cylindrical as well as collar bearings – are available in many dimensions and are supplied ready for installation from stock. Furthermore, we supply solid sintered and graphite bronze pieces up to a diameter and a length of 80 mm for further processing – special dimensions on request – as well as silencers made from sintered bronze.
| Material Standard SINT A50, MPIF: CT-1000-K26, SAE 841 - Bronze Mil-B-5687 Type 1, Grade 1, ASTM: B438 Grade 1, Type 2 Class A |
| Tolerances |
| Inner Diameter Tolerance +.000 -.001 in |
| Outside Diameter Tolerance+.000 -.001 in |
| Chemical Composition- Copper (87-90%), Tin (8-9), Iron (1.0% Max) Carbon (0.1%), other elements less than 0.1% |
| Oil Centent: 18-22% (V) |
| Density: 6.4-6.8 g/cm³ |
| Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest. |
| After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation. |
| Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F. |
| Maintenance-free bearing for general engineering applications |
