Load Capacity Data Sheet
Model Selection Guide:(Load &speed &stroke are necessary for a right model )
1) Lifting Dynamic Load KG( or KN)
2) Lifting Speed ____ mm/min
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
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)
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
6) Input shaft forms ____ (Input direction refer to the back side of nameplate)
SB:Standard double input
SAL:Single input:shaft left .
SAR:Single input:shaft right .
MCL:Flange left+single input
MCR:Flange right+single input
MDL:Flange left+double input
MDR:Flange right+ double input
