Large Cast Bronze Bushings SAE 841 with Self-Lubrication are
designed for heavy-duty applications that require exceptional wear
resistance and durability. These bushings are cast from
high-quality bronze alloy, SAE 841, which offers excellent
mechanical properties and corrosion resistance.
The self-lubrication feature of these bushings ensures smooth and
efficient operation even in high-load and high-speed conditions.
This eliminates the need for frequent lubrication and maintenance,
reducing downtime and operational costs.
The large size of these bushings allows them to be used in a wide
range of industrial applications, including machinery, equipment,
and vehicles. They can withstand extreme loads and temperatures,
making them ideal for use in demanding environments.
Overall, Large Cast Bronze Bushings SAE 841 with Self-Lubrication
are a reliable and cost-effective solution for heavy-duty
applications that require long-lasting and high-performance
bushings.
1: tin bronze is the lowest casting shrinkage rate of non-ferrous
metal alloy, can be used to produce complex shape, clear outline,
air tightness requirements are not high castings. 2: tin bronze is
very corrosion resistant in atmosphere, sea water, fresh water and
steam, widely used in steam boilers and sea ship parts.
3: phosphor tin bronze has good mechanical properties, can be used
as wear-resistant parts and elastic parts of high precision working
machine.
4: lead-bearing phosphor bronze is commonly used as wear-resistant
parts and sliding bearings.
5: zinc tin bronze can be used for high air tightness casting.
6: Aluminum bronze has good corrosion resistance, so it can be used
to make corrosion-resistant parts, such as propellers, valves, etc.
7: aluminum bronze under impact will not produce sparks, can be
used to manufacture spark free tool materials.
8: aluminum bronze has excellent thermal conductivity and stable
stiffness, as a mold material in tensile, calendering stainless
steel plate heat exchanger will not produce mucous membrane,
scratch the workpiece and other advantages, has become a new type
of mold material.
9: Aluminum bronze has high strength, good friction reduction and
good corrosion resistance, can be hot-machined, weldable, can be
used for high-strength, wear-resistant parts, such as bearings,
bushings, gears, turbines and so on. Has become a new type of mold
material.
10: Phosphor bronze is mainly used for wear-resistant parts and
elastic components.
11: phosphor bronze plates and strips are used for springs,
switches, lead frames, connectors, vibration plates, diaphragm
boxes, fuse clips, bushings, etc., especially for springs requiring
high performance and elasticity.

Taking high-strength copper alloy as the basic material, holes are
processed in its working face in a certain proportion according to
the working conditions and filled with solid lubricant. High-strength copper alloy provides a high bearing capacity while
solid lubricant can form a lower friction pair.Under the condition of dry friction, we design a pre-lubrication
film on the bearing surface to ensure that the solid lubricant can
be transferred to the dual member in the shortest time and form an
effective solid lubrication film.

Metal self-lubricating bearings can be used in dry friction, high
temperature, high pressure, corrosive environment, humidity and
occasions affected by chemicals. They are widely used in automobile
production line, water conservancy engineering, reservoir gate,
injection molding machine, continuous casting machine,
metallurgical machinery, mining machinery, turbine generator,
hydraulic generator and other fields.
Base material properties
1. Can be used for a long time without maintenance;
2. Designed for high static and dynamic load;
3. It has a very low and stable friction factor and no "adhesion"
phenomenon;
4. Dust resistance, corrosion resistance, impact resistance and
edge load resistance;
5. Metal substrate has good shock absorption capacity;
6. Can be used in a wide temperature range;
7. Suitable for reciprocating, rotating and swinging start
frequently and difficult to form oil film occasions.
