Product Details

When referring to  flanged bushings in inch sizes, it typically means that the dimensions and specifications of the bushings are based on the inch measurement system.  bushings, also known as oil-impregnated sintered bronze bushings, are self-lubricating bushings commonly used in various applications where lubrication may be difficult or impractical.

The flanged design of these bushings allows for easier installation and retention within housings or other components. The inch size specification indicates that the dimensions such as the outer diameter (OD), inner diameter (ID), length, and flange dimensions are provided in inches.

Some key points to consider when specifying  flanged bushings in inch sizes:

Dimensional Accuracy: Ensure that the inch dimensions provided are accurate and match the requirements of your application.
Material Selection:  bushings are made from oil-impregnated sintered bronze, which provides good wear resistance and self-lubricating properties. However, consider other factors like operating temperatures and chemical compatibility when selecting the material.
Flange Design: The flanged design provides additional retention and support. Make sure the flange dimensions are suitable for your application and housing design.
Installation Considerations: Proper installation is crucial for the performance and longevity of  bushings. Ensure that the bushings are pressed or installed into their housings without excessive force, which can damage the material.
Lubrication: Although  bushings are self-lubricating, some applications may require additional lubrication. Check the manufacturer's recommendations for lubrication requirements.
Remember to consult with your supplier or manufacturer for specific details and recommendations on  flanged bushings in inch sizes to ensure that you select the appropriate product for your application.

Characteristics of VSB-10 strips material

 

  • Very low stick-slip tendency

  • Low wear

  • Good chemical resistance

  • Low friction value

  • No tendency to weld to metal

  • Extremely swell-resistant

  • Does not absorb water

 

Preferred areas of application

 

  • Maintenance-free operation under dry-running conditions

  • Rotating or oscillating movements

  • Up to a velocity of 2 m/s

  • Linear movements

  • Temperature range -200 °C to 280 °C

 

Material composition

Strips Material composition

If these material sections are used to create slide paths, they have the following main functions:

 

  • Absorbing and transferring forces acting vertically to the running surface

  • Fixing moving components to each other

  • Ensuring guidance accuracy for axial movements over the entire service life

 

Strips are available in two material groups:

 

  • Material group P1 for maintenance-free, dry-running applications

  • Material group P2 for low-maintenance, lubricated applications

For the advantages of each group and help deciding which material group is best for the relevant use, please refer to the information provided in the section cylindrical bushes, flange liners and thrust washers.
 

VSB-10 Steel + Bronze Powder + PTFE/Fibre Bushings


· Bushing material suitable for lubricated applications
· self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Anti-friction bearing suitable for linear, oscillating and rotating movements

Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
 

Strusture

 
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
 
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.

 

3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
