Description
SAE 841 Powdered Metal Bronze, Sleeve Bearing | |||||||||
Specifications SAE841 SLEEVE Bearing Oil Impregnated Bronze | |||||||||
Material Powdered Metal / Oil Impregnated Bronze | |||||||||
Material Standard SAE 841 | |||||||||
Tolerances | |||||||||
Inner Diameter Tolerance +.000 -.001 in | |||||||||
Outside Diameter Tolerance+.000 -.001 in | |||||||||
Overall Length Tolerance .005 in | |||||||||
Chemical Composition- Copper (87-90%), Tin (8-9), Iron (1.0% Max) Carbon (0.1%), other elements less than 0.1% | |||||||||
MPIF: CT-1000-K26 | |||||||||
ASTM: B438 Grade 1, Type 2 Class A | |||||||||
SAE 841 - Bronze Mil-B-5687 Type 1, Grade 1 | |||||||||
Ideal for heavy loads at moderate speeds or light loads at high speeds - max Pv 50,000, P-Load 2,000, V-SFM-1,200 | |||||||||
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. | |||||||||
RoHS, REACH, DFARS compliant |
Cast Bronze Sleeve Bearing Standards
cast bronze standards are general-purpose bearings that provide the
best mix of functional properties, availability and economical
cost. They offer excellent load carrying capabilities with good
anti-frictional properties. They can perform over a broad range of
temperatures (up to 450 F°) and can readily be modified with grease
grooves, oil grooves or self-lubricating graphite plugs.
All standard stock sizes are also available in other materials such
as no-lead bronze, aluminum bronze, manganese bronze and cast iron.
Special requests are welcomed with flexible stocking arrangements
or just in time delivery schedules.
Characteristics
Sintered Bronze Bearings
Maintenance-free bearing for general engineering applications
Optimum performance under relatively light loads and high speeds
Produced by powder metallurgy process and therefore suitable for complex shapes
Availability
Bearing forms available in standard dimensions
Plain cylindrical bushes
Plain flanged bushes
Bearing forms made to order: cylindrical bushes and flanged bushes with non-standard dimensions, spherical bearings, tubes and rod blanks, customized bearing designs
Advantages Of Powder Metallurgy Process
· Do not need or only very little machining |
· High usage rate of material(more than 95%) |
· Parts size consistency is good and stable. The precision can reach 0.01mm. |
· The material composition can be adjusted according to the customers’requirement of the parts performance. |
· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness. |
· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do. |
· Because suitable for mass production, the production efficiency is high and the cost is lower than machining. |
