Bronze alloy Gleitlager bushings, commonly referred to as sliding
bearings or bushings, are precision-engineered components that
incorporate graphite inserts for enhanced performance. These
bushings are designed to provide smooth and reliable sliding motion
in various mechanical and industrial applications.
The bronze alloy base of these Gleitlager bushings offers excellent
strength, durability, and corrosion resistance. Bronze alloys are
widely used in sliding bearings due to their ability to withstand
high loads, pressures, and temperatures. The alloy's composition
typically includes copper, tin, and other elements that enhance its
mechanical properties.
The key feature of these Gleitlager bushings is the graphite
insert. Graphite is a natural lubricant that possesses low friction
coefficients and excellent wear resistance. By embedding graphite
particles into the bronze alloy base, the bushings achieve
self-lubricating properties. This eliminates the need for frequent
relubrication, reducing maintenance costs and downtime.
The graphite insert also improves the bushings' sliding
performance. As the bushings rotate or slide against other
surfaces, the graphite particles act as a lubricating layer,
reducing friction and wear. This ensures smooth and reliable
operation, even under high loads and speeds.
Bronze alloy Gleitlager bushings with graphite inserts are widely
used in various applications, including hydraulic systems, pumps,
compressors, and other industrial equipment. They are particularly
suited for applications where precise alignment and smooth
operation are critical.
In summary, bronze alloy Gleitlager bushings with graphite inserts
offer a reliable and cost-effective solution for ensuring smooth
and reliable sliding motion in mechanical and industrial
applications. The combination of bronze alloy's strength and
durability and graphite's self-lubricating properties makes these
bushings a preferred choice for a wide range of applications.

It is a high-performance solid lubrication product that is inserted Graphite or MoS2 solid lubricant on a matrix of colliers brass. It has broken through the limitation of general bearing lubrication
by oil film. In the use process, through the friction heat to make the solid
lubrication and the shaft friction, the formation of oil, powder
co-lubrication of excellent conditions, not only protect the shaft
from wear but also make the solid lubrication characteristics
eternal. Its hardness is higher than ordinary copper sleeve one

Feature
·The reduction in operating costs significantly reduces the use of
lubricants and equipment maintenance costs, and also eliminates the
risk caused by insufficient oil supply.
·There is no need to save the cost and time of oil supply device,
oil injection hole, oil tank processing and oil supply device,
processing fee, assembly fee, etc., which can greatly reduce the
manufacturing cost.
·The recovery and environmental protection of lubricating oil do not
require waste oil recovery and treatment, which is conducive to
environmental protection.
·Shortening the design time oil-free can greatly simplify the design
and structure, reduce the cost and save the design time. In
addition, the use of self-lubricating bearings can also improve the
mechanical properties, prolong the service life and improve the
reliability and other aspects to obtain significant results.
Use method and notes
·In the possible case, the design uses the standard specification
as far as possible.
·Please note that there is no foreign body in the assembly.
·After using the sliding surface, formed by solid lubricant oil
film in surface with black or gray-black phenomenon, please do not
scrub, as usual.
·Before the assembly, if the lubricating oil applied to the
grinding parts, can shorten the running-in period, conducive to the
operation of machinery, operation.
·When the assembly should be slowly pressed into, it is strictly
forbidden to beat, so as to avoid damage to the bearing and
deformation.
·Design, different parts should be selected with appropriate
material, in order to improve the mechanical performance, to extend
the service life of the bearing.
·In the high load, reciprocating motion, the proposed use of screw
fixation.
·In freshwater, seawater, and in the sea, on the use of stainless
steel or surface plating.
Advantages
·Flexible design, simple, convenient with wide applications
The designing of the oil-feeding system is both a labor-consuming
and time-consuming job. Therefore, the neglecting of the
oil-feeding apparatus in the designing of solid Lubricant bearings
saves the cost of the oil-feeding apparatus. Besides, for various
specific circumstances, the solid lubricant bearings can be
designed into various types to meet the requirements thereof. The
use of solid lubricant bearings can greatly reduce the cost of
mechanical maintenance and oil.
· FunctionaI in absence of oiI
Since the Iinear expansibility of solid Iubricant is greater than
metallic matrix's, when the movement of solid lubricant bearings
start, the Iubricant is transferred onto the parts in abrasion thus
realizing the self-lubrication. Therefore, the lubricant bearings
can be used in circumstances where oiling and greasing are
difficult or impossible and they perform excellent Lubrication even
under low-speed and high Road circumstances.
·Cost efficiency
The traditional mechanical designing requires frequent oiling
maintenance; oil gauge check shall be performed to ensure the
passage of the oil supplying apparatus is clear. Since the
periodical oiling can cause pollution to the machines themselves as
well as to the ambient surroundings, resulting in an increase of
the maintenance cost,the realization of self-lubrication can not
only make the environment clean but greatly reduce the Lubricating
costs as well.
· Excellent performance under high-load, Iow-speed circumstances
The solid lubricant bearings are made of rotational cast
high-strength copper as the matrix, which functions as Road
bearers. Besides, lubricant bearings use specially formulated
graphite as Lubricant, ensuing excellent self-lubrication.
Combining the advantages of both the matrix and Lubricant,
lubricant bearings are capable of exerting their wonderful
performance in circumstances with high load and low speed.
· In circumstances where it is difficult for the oiI films to
generate, such as the alternative movements, swinging movements and
frequent on-and-off, solid lubricant bearings highlights their
excellent resistance to abrasion. As the principle of the arrangement of lubricant bearings
Iubricant is to ensure that each part of the equipment is involved
in the Iubrication throughout the movement, the Iocation of the
Iubricant shalI be determined according to the movement direction
of the parts in abrasion.
· Excellent chemical resistance and corrosion resistance
The Lubricant for lubricant bearing is formulated out of the
abrasion-resistant materials such as graphite and PTEE and has
stabilized molecular structure. The metallic matrix can be selected
according to the various chemical resistance and corrosion
resistance accordingly. Therefore, the lubricant
bearing enjoys high chemical resistance and corrosion
resistance.
·The cost of the products is more competitive and compared with
other products of the same kind, the solid lubricant bearings
feature in longer service hours, less maintenance, longer
replacement period, and better performance.
