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.

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.
