RG7 Tin Bronze Bushing – C93200 Bearing Bronze

C93200 Tin Bronze Bushing has excellent machining properties, good hardness, as well as strength and wear resistance with excellent antifriction qualities.

What Is Tin Bronze?

Tin bronze is an alloy primarily made up of copper and tin, with the addition of other elements such as zinc, lead, or phosphorus to enhance specific properties. The typical copper content in tin bronze ranges from 80-95%, while it accounts for 5-20%. The remaining elements are present in trace amounts.
Tin bronze bushings are versatile and reliable components used in various industries due to their unique combination of properties. These bushings are made from a copper-tin alloy known as tin bronze, which offers excellent strength, durability, wear resistance, and corrosion resistance.

Tin Bronze Bushing for Hydraulic Cylinders: A Durable Solution for Smooth Operations

Tin Bronze Bushing for Hydraulic CylindersHydraulic cylinders are essential components in various mechanical systems, efficiently converting hydraulic energy into mechanical force through linear or oscillating motion. With their simple yet reliable design, they find widespread use in hydraulic systems across industries. The inner lining of the cylinder, known as the bushing, plays a critical role in protecting the cylinder and reducing friction between the cylinder and the piston. Moreover, the use of bushings simplifies the cylinder’s construction and manufacturing process, allowing for easy maintenance by simply replacing worn-out bushings instead of the entire cylinder.

Tin Bronze: An Ideal Alloy for Hydraulic Cylinder Bushings

Hydraulic cylinders are prone to failures caused by worn-out seals, cylinder barrel erosion, internal surface scratches, corrosion, and piston or piston rod damage. The sealing performance of the hydraulic cylinder significantly affects the equipment’s overall performance. Therefore, the material choice for the cylinder bushing must meet essential criteria, such as wear resistance and corrosion resistance, making tin bronze a suitable candidate.

Tin bronze, an alloy with high mechanical strength, anti-wear properties, and corrosion resistance, offers excellent machinability and performs well in brazing and welding processes. Its low coefficient of thermal expansion and non-magnetic properties make it an attractive choice for hydraulic cylinder applications. The combination of high strength and excellent castability further enhances its suitability for use as a copper bushing in hydraulic cylinders.

Role and Benefits of Tin Bronze Bushings in Hydraulic Cylinders:

Protecting the Cylinder Barrel and Reducing Wear:

The primary purpose of using a tin bronze bushing is to safeguard the cylinder barrel from direct wear and damage. The bushing acts as a sacrificial layer, absorbing friction and preventing it from affecting the critical components of the hydraulic cylinder. This protective feature significantly extends the lifespan of the cylinder and reduces maintenance requirements.

Simplifying Cylinder Structure and Manufacturing:

Incorporating tin bronze bushings simplifies the design and manufacturing process of hydraulic cylinders. The bushing can be readily inserted into the cylinder barrel, streamlining production and assembly. Moreover, this approach reduces the complexity of the cylinder’s construction, leading to cost-effective manufacturing and increased productivity.

Facilitating Easy Maintenance:

Hydraulic cylinders are subject to wear and tear over time, and regular maintenance becomes necessary. By using tin bronze bushings, maintenance becomes more convenient and cost-effective. When the bushing wears out, it can be easily replaced without the need to replace the entire cylinder. This not only reduces downtime but also saves on replacement costs.

Tin bronze bushings have proven to be a reliable and durable solution for hydraulic cylinders. Their high mechanical performance, anti-wear properties, corrosion resistance, and ease of manufacturing and maintenance make them an excellent choice for protecting cylinder barrels and ensuring smooth and efficient operations in hydraulic systems. The use of tin bronze bushings in hydraulic cylinders continues to contribute to the reliability and longevity of various machinery across industries.

C93500 Tin Bronze Bushing For Sale

C93500 High Leaded Tin Bronze, SAE 66

C93500 High Leaded Tin Bronze is used in a variety of applications. Typical uses for Small bearings and bushings and bronze backing for babbitt-lined automotive bearings。

C93500 high-lead tin bronze is similar to C93200 and C93400, but has a lower tin content and a higher lead content. Tensile strength is reduced due to the lower tin content, but the alloy has greater ductility. The higher lead content reduces the coefficient of friction and aids in backsealing in the event of lubrication failure. It is suitable for general purpose high-speed bearings with low loads. It is available in alternative specifications SAE 66, SAE J461/J462, QQ-C-390B, QQ-B-1005 Comp14, Mil-B-11553 Comp14, AS 1565, BS 1400 LB4, and EN 1982:2008 GC CC494K.

Manufacturing Processes For Tin Bronze Bushings

  • Casting: Casting is a common method used in the production of tin bronze bushings. Molten metal is poured into a mold and allowed to solidify, taking on the desired shape of the bushing. This process allows for the creation of complex shapes and sizes, making it suitable for a wide range of applications.
  • Powder metallurgy: Powder metallurgy is another technique utilized for manufacturing tin bronze bushings. In this process, metal powders are combined, compacted, and sintered to form a solid part. This method offers high precision, dimensional accuracy, and excellent material properties.
