Ball screw for Semiconductor Unit

ball screw for semiconductor unit for Electric component insert machine; Printing circuit borad holder; High accuracy grade

A  ball screw for Electric component insert machine andPrinting circuit borad holder of semiconductor unit 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 precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw.

In order to make use of function of ball screw,

ball screw must be lubricated in working condition. There are following lubrication methods:

Lubrication greaseThe quantity of lubrication grease is generally 1/3 of inner space of nut. Before the ball screw leaves factory, Lithium lubrication grease GB7324-94 2# has been brought into inner space of nut.

Lubrication oilThe quantity standard of lubrication oil is shown as Tab.16. But it is changeable as difference of travel, sort of lubrication, use condition( heat control). Please pay attention.
