Product Description

Cradle bearings for axial piston pumps and motors Wrapped Bearings | Sliding Bearing Technology


Axial piston pump bushing & motor bracket bearings

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


Bearing Application Requirements

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.

Typical Applications


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.
