Product Details

The CuSn8 Wrapped Bronze Bushing is a type of bronze bushing that is constructed using CuSn8, a specific alloy of copper and tin. This alloy, known for its exceptional wear resistance, corrosion resistance, and good strength, is ideal for applications requiring durable and reliable bushings.

The "wrapped" design of the bushing refers to the fact that the CuSn8 bronze material is wrapped or formed around a central core or mandrel. This construction technique allows for precise shaping and sizing of the bushing, ensuring a tight and secure fit within the application.

CuSn8 Wrapped Bronze Bushings are commonly used in a variety of industrial applications, including pumps, motors, compressors, and other rotating machinery. Their durability and reliability make them a trusted choice for maintaining smooth and efficient operation in demanding environments.

The CuSn8 alloy provides superior wear resistance, ensuring that the bushing can withstand repeated friction and abrasion without excessive wear or damage. Additionally, the corrosion resistance of the alloy helps protect the bushing from rust and corrosion, extending its service life.

Overall, the CuSn8 Wrapped Bronze Bushing is a high-performance bushing solution that offers excellent wear resistance, corrosion resistance, and precise fit, making it suitable for a wide range of industrial applications.

These bronze bearings have been developed to for slow speed, high load applications, especially suited for oscillating motion and are perfect for the construction, mining/quarrying, agriculture and automotive industries.

Our Viiplus range of plain bearings are avialble with lubrication pockets, thru-holes and grooves. This range is available in metric sizes only.

Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.

Wrapped bronze bushing is made of tin-bronze CuSn8P with its surface punched with diamond oil sockets which are preserved for oil saving. It has good anti-fatigue, anti-erosion anti-abrasion and load capacity.

Materials

 

lagerbuchse are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.

 

Lubrication

 

Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft. For heavily contaminated applications, we recommend sealing off the bearing. This will protect both the bearing and the lubricant.

6. Chemical resistance.
Initial pre-lubrication at assembly required... Chemical Compositions lagerbuchse are wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.

 

Lagerbuchse | Metric Size

 

Viiplus lagerbuchse are available in metric sizes as straight or flanged bushings. They are wrapped from strips and calibrated. These bushings are an excellent solution for dirty environments where high levels of contamination make relubrication necessary. They are resistant to shock loads and vibrations at slow speeds.

The diamond-shaped lubrication pockets in the sliding surface need to be filled initially with grease. A good quality lubricant reduces friction and wear by separating a bronze bushing from its shaft. To protect the bushing and lubricant in highly contaminated environments, viiplus recommends using seals.

 

Applications

 

Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

  • Agricultural vehicles
  • Lifting gear
  • Offshore
  • Excavators

 

Characteristics

 

– High load capacity
– Works well in dirty environments

Main Factors that Influence the Service life of the Bushing


1).PV Value
PV value is an effective criterion to calculate the service life of TCB900/TCB902. If there is need to prolong the service Life, PV value must be reduced.
2).Environment Temperature
Service life of the TCB900/TCB902 will shorten in higer ambient temperature .
3).Roughness
Service life of TCB900/TCB902 can be greatly improved if its mating axis is made of chrome-plated stainless steel with hardness more than 50HRC and surface roughness among 0.4~0.63.
