What is Centrifugal Cast Bronze Bushing?
Centrifugal cast bronze bushing is a cylindrical plain bearing that uses copper-tin alloys and manufactured by centrifugal casting process.
Shata Machinery is a top cast bronze bushing supplier in China, producing non-standard centrifugal cast bushing, bearing, roller, sleeve, pipe and other castings.
Types of Bronze Bushings/Bearings
Types by material:
- Tin bronze bushing: Balanced strength, high wear resistance and corrosion resistance. Centrifugal casting makes it with denser grains and improved durability. Common tin bronze for bushing including C93200, C90700, C90500, CuSn10Pb10, ZCuSn5Pb5Zn5.
- Leaded bronze bushing (leaded tin bronze bushing): Adding lead to tin bronze, we can get leaded bronze. Leaded bronze inherits the good wear resistance of tin bronze and improves self-lubricating performance due to lead content. Common leaded bronze for bushing including C93200, C93800 (CuPb15Sn8), C93700 (ZCuPb10Sn10), Pb15Sn7, Pb20Sn5.
- Aluminum bronze bushing: High strength, high corrosion resistance. Common aluminum bronze for bushing including ZCuAl9Fe4Ni4Mn2 (C95500), QAl9-4 (C95400), QAl9-2, ZcuAl10Fe3 (C95200), CuAl10Fe5Ni (C63000).
Types by structure:
- Straight sleeve bushing (Cylindrical bushing): A cylindrical bushing that designed for reducing rotating wear for shaft.
- Flanged bushing (Sleeve with flange): One end is equipped with a flange for positioning and prevent movement.
- Wear sleeve (Thin-walled sleeve): The wall is very thin and mainly serves to protect the shaft. Centrifugal casting has obvious advantages in producing thin-walled parts.
- Tapered bushing (Taper sleeve): Taper with center hole or conical outer shape. The taper ensures good centering and locking.
- Step bushing (Multi-step sleeve): Step or steps on the center hole or outer diameter
- Double flange bushing: Flanges at both ends of the bushing, used for bidirectional positioning and anti-axial movement.
What is the Purpose of Bronze Bushings?
- Load supporting: providing stable surface for rotating or sliding, and ensuring heavy load uniformly distributed
- Reduce friction: Smooth surface of the bronze bushing can minimize the friction, reducing energy consumption and heat generation
- Wear resistance: Extending service life
- Noise reduction and vibration reduction
- Corrosion resistance
What Bronze is Good for Bushings?
It depends on the specific applications:
|
Bronze |
Applications |
Example |
|
Tin bronze |
High-load, low speed |
Machine tool shaft bushing, reducer gear bushing, drum bushing |
|
Leaded bronze |
High-speed that requires self-lubrication |
Mill roll bushing, hydraulic motor sleeve, compressor crankshaft bushing |
|
Aluminum bronze |
Marine, heavy-duty, damp, or corrosive environment |
Ship propeller shaft bushing, seawater pump bushing, heavy-duty excavator connecting rod bushing |
Is Brass or Bronze Better for Bushings?
Bronze bushings have better comprehensive performance than brass bushings, including strength, wear resistance, corrosion resistance, longer service life, and lower maintenance frequency.
Brass bushings are cheaper and cost-effective for light-load, low-speed and no corrosion industrial equipment, such as household sewing machines, small farm machines, simple conveying equipment.
