Ball Leading Screw |
A ball screw is a mechanical device for translating rotational motion to linear motion. A threaded shaft provides a spiral raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high ...

Linear Motion Shaft |
The linear optical shaft can ensure high accuracy of OD tolerance, straightness, circular degree and surface roughness of shaft with accumulated techniques.
The allowable tolerance of OD tolerance of linear optical shaft to diameter line bearing incircle diameter has proper clearance. The tolerance of solid shaft must be adjusted under precise operation so as to prevent clearance or added with slight pressure. ... |

Linear Guide Rail And Block Assemblies |
The roller linear guide assembly consists of guide, slide, steel ball, reverser, retainer, seal end and baffle etc. When the guide and slide act relative movement, the steel ball will roll along the four annealed precise ground raceways on the guide and enter into return hole through reversal unit (reverser) at the end of slide before entering into raceways, the steel ball rolls recurrently in this way. ...
