MR series Hydrostatic Bearing Rotary Actuators/Cylinder
- Product Details
- Company Profile
? No sealing gaskets, free from sliding friction and wear, no stick-slip effect in normal applications; great frequency response. ? Extraordinary high accuracies and stability of control and movement-High test frequency and speed with excellent sensitivity. ? Sustain high lateral load, automatically constant alignment. ? Bearings and piston coated with special plastics, giving exceptional reliability and endurance in service. ? Repairability for extended service life ? Low overall operational and maintenance costs
Hydrostatic bearing actuator has no sealing gaskets. With the help of special designed hydrostatic bearing unit, the piston rod automatically regulates itself that ensures constantly alignment between piston rod and cylinder housing and central guiding. While bearings center the piston, all sliding surfaces in actuator are separated by oil film under pressure; this oil film in hydrostatic bearings exists before piston moves and is maintained even under lateral force so to exclude friction & wear. Hydrostatic bearing actuator offers much high performance and fits in well with testing tasks where high accuracy of control and measurement is essentially desired.
