4) Installation:

Installation 

A:Upright installation for lifting--Translating screw can do axial motion with a guide rail or a non-rotation load .

B:Inverted installation for lifting or pressing--Same as type A 

C:Upright installation for lifting--Keyed screw anti-rotation,do axial motion     

D:Inverted installation for lifting or pressing--Same as type C  

 

  Ef

E:Upright ---screw fixed rotation without lifting,traveling nut do axial motion within effective stroke.

F: Inverted--Same as type F.


5) Screw Top End (the top end type for connecting screw with load)

 

Screw Top End

T:Top Plate: enlarge the plane between the lead screw and load interface to enhance the stability of screw axial motion, suitable for platform application.

H:Clevis End: connecting load with a bolt joint for flipping motion.

S:Threaded End:connecting load's internal thread with screw`s external thread, usually need to add a locked nut.

R: Plain End:top end is unfixed connection with load,or secondary machining of top end made by users.

U:Forked Head: same as [H"type but with shape [U".

E/F:Nut type, screw fixed rotation,traveling nut do axial motion
