Angled-surface slot-compensated hydrostatic bearing (ASHB) is a novel type of hydrostatic bearing which is potentially applicable in rotary tables. However, it has not been sufficiently studied in available literature. In this paper the mathematic model for ASHB was built and solved by the finite element method (FEM). The influence of semicone angle on static and dynamic performance characteristics was theoretically investigated. The simulated results have been compared with that of the traditional fixed slot-compensated hydrostatic bearing (FSHB) on the same geometric and operating conditions. Results show that the performance of ASHB is better than that of FSHB; the studied bearing with a large semicone angle is superior in power consumption; the clearance width ratio of the restricting gap to the bearing gap has an obvious effect on bearing performance.
