Bronze Brass Thrust Washers CuSn12 are thrust components that are crafted from CuSn12 alloy, a copper-based material containing a specific amount of tin (Sn) and other elements. CuSn12 is a type of bronze alloy that exhibits high strength, good hardness, excellent corrosion resistance, and good thermal conductivity. These properties make CuSn12 thrust washers suitable for applications where durability, wear resistance, and stability are crucial.
Thrust washers are used in various mechanical systems to provide a smooth and reliable interface between moving parts. They are often installed between rotating shafts and stationary components to reduce friction and wear, ensuring smooth operation and extending the service life of the system.
CuSn12 bronze brass thrust washers are widely used in industries such as manufacturing, automotive, aerospace, and heavy machinery. Their ability to withstand high loads and resist wear makes them ideal for applications involving high-speed rotation, heavy-duty operation, or exposure to harsh environments.
In summary, Bronze Brass Thrust Washers CuSn12 are thrust components crafted from CuSn12 alloy, a copper-based material with excellent mechanical and chemical properties. These washers provide a reliable and durable solution for reducing friction and wear in mechanical systems, enabling smooth operation and extending the service life of equipment.

For parts with high friction and deterioration; Heavily loaded
bearings, gears, bushings, worms, hydraulic high-pressure devices.
Parts subject to high friction (e.g. thrust bearing sectors,
electric pumps, plates subject to friction, etc.).
• Very marine corrosion resistance
• high resistance to friction, wear or pressure
• good mechanical strength
• expensive and heavy
Maintenance-free (self-lubricating)
The material of the oil-free thrust washer is made of sturdy cast
bronze based metal with special solid lubricants incorporated.
prelubrication under extremely high / low temperature conditions at
low speed. This material provides a maintenance free bearing
solution, especially for high loads, intermittent movement of
oscillations.
This type of bearing can be applied in dry, high temperature, high
pressure, corrosive environments, with water or other chemicals,
when no oil can be introduced.
It is now widely used in the automotive product line, hydraulic
engineering, dam gates, plastic industries, successive casting
machines, steel rollers in the metallurgical industry, mineral
machinery vessels, turbo generators, hydraulic turbines and
injection molding machines.
Oilless Bushing forms available in standard dimensions
Metric self-lubricating bearings and imperial oilless bushings made to order: standard bushing forms in special dimensions, half-bushings, special shapes obtained by stamping or deep drawing, customized bushing designs
Our material is made of strong cast bronze based metal with special
solid lubricants embedded. The base metal withstands high load and
the solid lubricants provide self-lubrication. The bearing shows
excellent performance without pre-lubrication under conditions of
extreme high/low temperature with low speed. This material provides
a maintenance-free bearing solution, particularly for highload,
intermittent of oscillating motion.
This type of bearing can be applied in dry, high temperature, high
pressure, corrosive environment, with water or other chemicals when
it is not possible to introduce oil. It is widely used in the
automotive product line, water engineering, dams, plastics
industries, later casting machines, steel rollers in the
metallurgical industry, mineral machinery, ships, turbo generators,
water turbines and injection molding machines. etc..
1. Can work without oil for a long time
2. Extremely high lifting capacity, good anti-wear properties and
less friction.
3. Especially suitable for low speed and high load.
4. Suitable for reciprocating, oscillating or intermittent motion
when the oil film is poorly formed.
5. Good chemical and anti-corrosion performance.
6. Can be used in a wide temperature range from -40 ℃ to + 300 ℃.
