Magnetic bearings due to expensive, complex control system, the heating problem is difficult to solve, and therefore can not promote the use of the high-speed spindle unit.
Water-based hydrostatic super-precision bearing is currently the more popular research topic, it is the use of water has a large heat capacity, bearing temperature rise is small features, a partial solution to the ordinary move, hydrostatic bearing fever serious problems, mainly used in low-speed heavy-duty applications.
Air hybrid bearing radial stiffness and a low-impact, but high-speed performance, generally used in ultra-high speed, light load, the precision spindle.
Angular contact ball Slewing bearing dn value in 2.0 × 106 following the application of a high-speed spindle unit, whether it is the speed limit, all aspects of carrying capacity, rigidity, precision can satisfy the requirements and have been standardized, inexpensive,
Angular contact ball bearings but also through the following methods to improve performance.
Clutch release bearing work, the clutch pedal force will be transmitted to the clutch release bearing. Clutch Bearing Clutch pressure plate toward the center, so that the pressure plate is pushed away from the clutch, the clutch plate and flywheel separation. When the clutch pedal is released, the pressure plate will spring pressure inside the pressure plate before the push, pressure to the clutch, the clutch plate and clutch bearing separation, and complete a cycle.
