SN-H Steel Bushing
SN-H Steel Bushing
The inner surface of SN-H steel bushing bearing is processed with
various types of oil grooves, which improves the surface hardness
and wear resistance after heat treatment. It is suitable for
heavy-duty joint parts of construction machinery such as
excavators, rotary drilling rigs, large loaders, wall grab and so
on.
The steel bushing bearing of our company is based on 45#, 40Cr,
20CrMo, GCr15 and other materials. From raw materials to finished
products, each process is strictly controlled to ensure the product
quality. It produces bushing with high wear resistance, high
surface hardness and strong internal toughness.

blind hole oil storage steel bushing
blind hole oil storage steel bushing
The inner surface of the blind hole oil storage steel bushing is
sprayed with molybdenum disulfide, which has the advantages of
low friction coefficient and good wear resistance, and can work under the condition without oil or with little oil. Products are
widely used in construction machinery, heavy duty high load equipment.

Product Advantages
The inner wall of the bushing is evenly distributed with blind
holes with conical cross-section.
The lubricating oil wedge is formed naturally during the grinding
process of the inner hole of the bushing
The oil storage capacity of oil pocket is large, which is 3~5 times
of that of ordinary oil tank and can be free from maintenance for a
long time.
The oil pockets are evenly distributed on the inner wall, and the
center distance of the oil pockets in the circumferential direction
is fixed. No matter how large the bushing is, it only needs a small
rotation angle to fill the inner surface of the bushing with the
oil cloth, without lubrication dead area.
The oil pockets evenly distributed in the inner holes do not damage
the bearing capacity of the inner wall of the bushing and prolong
the service life of the bushing.
Material: 20CrMnTi, 20CrMo and other low carbon alloy steels
Surface treatment: Molybdenum disulfide spraying
SN-X Mesh steel bushing
Due to the combination of double surface treatment and special
surface morphology, the mesh bushing has excellent wear resistance
and seizure resistance. This cross hatch morphology provides a
grease reservoir in the load area and can remove abrasive
particles. They are suitable for working under harsh working
conditions: High pressure, wear, impact and corrosion. Mesh sleeves
are alternatives without cross-hatches. They provide excellent
performance under high static loads (low dynamic pressures) and
small oscillations (wear resistance and seizure resistance...)

SN-B Bimetallic composite self-lubricating bushing
The bimetallic self-lubricating graphite copper bushing is based on
low carbon steel, and the inner surface is Tin Phosphorus Bronze,
the thickness can be customized 0.5-5mm. The ZCuSn10P1
tin-phosphorus bronze has high hardness and wear resistance. It can
be used to manufacture parts that work under heavy load, high speed
and high temperature, and the copper bushing is subject to strong
friction. The surface of the bimetallic self-lubricating graphite
bushing is inlaid with a special formula of solid lubricant at a
certain angle and density, which is precisely processed, so that
the copper bushing has the advantages of high wear resistance, high
hardness and high toughness.

The bimetallic self-lubricating graphite copper bushing is a novel
lubricating bearing with the characteristics of metal bearing and
self-lubricating bearing. It is loaded by metal matrix, and the
solid lubricating material with special formula plays a lubricating
role. It has the characteristics of high bearing capacity, impact
resistance, high temperature resistance and strong self-lubricating
capability. It is especially suitable for occasions that are
difficult to lubricate and form oil membrane, such as heavy load,
low speed, reciprocating or swinging, and it is also not afraid of
water erosion and erosion of other acids.
