  Screw jack, an industrial essentials, is a common lifting equipment.  Due  to  the   independent  characteristics of screw jack, such machine has its unique use requirements which can not be used beyond the scope, otherwise it is prone to failure.

 

 

D1 Speed

 

The maximum speed should be below 1500 rpm as the worm gear structure adopted for the screw jack,when the stroke longer than 300 mm, please refers to the datasheet for its stability. 

 

D2 Power

 

 

  There is a max input power for each model of screw jack, which means the input speed  should not  be  exceed  the peak.

 

D3 Loading

 

 

  The torque should be calculated if the bearing reaches 25% to 100% of the full, which can be drawn by the loadi-ng percentage multiply by the full torque. The max input power is related to working temparature.

 

 

D4 Self-locking

 

 

  All NOSEN screw jacks equip with the function of self-locking.

 

D5 Leteral force

 

 

  The screw can not bear the lateral force. If there is, a guide rail must be supported that.
