AT A GLANCE
Variable displacement axial piston pumps are used in high power hydraulic systems in many industries, including aerospace, automotive, construction equipment, agricultural equipment, machine tools and others.
These pumps provide a variable flow to system actuators from zero to their maximum capacity. The variation in flow is effected by the change in position of the swash plate.
The technical requirements for a plain bearing in this application and specific function are among the most demanding of any high power hydraulic component. In addition to temperatures ranging from -50°C to +140°C and wide range of lubricant viscosities, the cradle bearing must be able to withstand extreme, high load oscillating speeds and boundary lubrication conditions.
This requires the bearing to offer high resistance to wear, fatigue and flow erosion.
Compared with bimetal bronze bearings, high precision HI-EX® hydrodynamic composite bearings offer the following advantages:
