Bush solution
The technical requirements and specific functions of sliding
bearings in this application are the most demanding requirements of
any high-power hydraulic components.In addition to withstand the temperature range in - 50 ℃ to + 140 ℃
as well as the wide range of lubricant viscosity change, must be
able to withstand extreme high load bearing oscillation velocity and boundary lubrication conditions.
An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand-alone pump, a hydraulic motor or an automotive air conditioning compressor.
Variable displacement axial piston pumps are used in many
industries of high power hydraulic systems, including aerospace, automotive, construction
equipment, agricultural equipment, machine tools, etc.These pumps
provide variable flow from zero to maximum capacity for the system
actuators.The change of flow is realized by the change of the
position of the swash plate
This requires bearings to provide high wear resistance, fatigue and flow erosion
Hydrodynamic composite bearings - advantages
Compared with bimetallic bronze bearing, high
precision;Hydrodynamic composite bearing has the following
advantages:
The PEEK (polyether ether ketone) is added to the bearing coating
to extend its service life and provide excellent wear resistance over a wide range of loads, speeds, and temperatures.
The addition of PTFE (polytetrafluoroethylene) to the bearing coating reduces friction
and improves the response of flow rate changes to increased
efficiency
Lead-free bearing material in accordance with EVL directive and RoHS and
regulations
Wrapped Bearings
Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound
of PTFE and Lead as its surface. It offers the property of good self-lubrication, low wear, low friction good sliding
characteristics, low noise. It has been widely applied to various mechanical sliding
positions, such as textile machinery, printing machinery, hydraulic
pressure transit vehicle, tobacco machinery, gymnastic instrument
and agricultural machinery etc.
VSB-80 Bimetallic composite bearings
Steel shell backed with a lead bronze lining bearing material for
oil lubricated applications. This material has high load capacity and good fatigue properties. It is widely used in automotive applications such as
compressors, steering gear, power steering, pedal bearings,
king-pin bushes, tailgate pivots, mechanical handling and lifting
equipment, hydraulic motors, agricultural machinery etc.
·
Bimetal bearing with steel backing and bronze overlay
· Particularly suitable for high specific loads with oscillating motion and low frequency
· Applicable in rough operation conditions
· High load capacity, very good resistance to fatigue strength at
higher temperatures
1.Sintered bronze lazer: God wear resistance and excellent load carrying capacity.
2.Steel backing:Setting the foundation of the bushings,the steel back provides exceptional stability, load carrying and heat dissipation
characteristics.

This material is recommended to be used under the medium speed and medium load condition with oil or grease lubricating. It is widely used for
motor rod ends, Kingpin bushing, undercarriage rollers, hydraulic
cylinder rod eyes of construction machines and spherical joint
bearings of agricultural machines. Because this material is with
lead, the specific parts are not allowed to be used according to
certain laws or regulations.
