Sintered Bronze Wrapped Bush 6530 Split Metric Size refers to a
bush made of sintered bronze material, which is wrapped and has a
split metric size. This type of bush is commonly used in mechanical
equipment and machinery to provide a smooth and wear-resistant
interface between moving parts. The sintered bronze material
ensures good friction properties and durability, while the split
metric size allows for easy installation and adjustment.

Quality Bushings & Bearings. Custom Self-lubricating Bearing
Solutions.
Bushings, or plain bearings, operate with sliding motion between
the moving surfaces. Bushings are selected based on the rotating
speed and the applied load. Most bushings do not require additional
lubrication to operate.
Self-lubricating bronze composite bushings consist of a layer
sintered on a brown strip. These bushings are corrosion resistant
and suitable for high temperature applications that can be made without the use of oil requiring
long duty cycles.
This type of self-lubricating bearing is used in the radial or
axial direction, especially in the steel and cement industries.
Self-lubricating -bronze composite bushings can be used in panels
as bridge supports, since the thick sliding layer on the inner
surface can withstand loads of up to 140 N / mm².

transfer film, which effectively covers the contact surface of the
socket assembly, forming an oxide type solid lubricant film.
2. sintered bronze powder 0.20-0.35mm, provides max. thermal
conductivity away from the bushing surface, also serves as a
reservoir for the -lead mixture.

Metal-Polymer Bronze Backed Plain Bearing Bushing Characteristics
Composite Plain Bearing Dry type composite plain bearings are
mainly used in bearing assemblies where heavy loads have to be
carried and where rotational or oscillatory movements are
relatively slow.
- Very good wear and low friction performance over a wide range of
loads, speeds and temperatures in dry running conditions
- Suitable for lubricated applications
- Suitable for linear, oscillating and rotating movements
- Bronze back offers improved corrosion resistance in humid/saline
environments

Application areas
This type of bearing is used radially or axially, particularly in
the steel and cement industries.
Industrial: aerospace, agricultural equipment, construction equipment,
material handling equipment, forming machines - metal, plastic and
rubber; office equipment, and scientific equipment, packaging
equipment, pneumatic and hydraulic equipment cylinders, pumps and
motors, railways and tramways, textile machines, valves, etc.
Other: marine and offshore equipment, other applications in water or in
outdoor environments
Bronze Backed Bushing Typical Applications
It can meet the demanding criteria of long life and trouble-free
performance with or without lubricant, especially for high chemical
resistance requirements.
The Bronze Backed bushing is widely used in steel metallurgy in
applications such as roller groove bushings of later casting
machines, concrete injection pumps and screw conveyors for
concrete. They can also be made of steel housings or be transformed
into flanged bushings that can move in both radial and axial
directions.
The Bronze Backed bushing is particularly suitable for high
temperature environments where no oil is efficient and the machine
must operate under consecutive long term conditions.
