SWLB Ball Screw / Screw Jack

Description

The SWLB lead screw elevator is made by Shanghai Dianmai Transmission through improving the traditional ball screw, enabling the elevator to have the advantages of higher efficiency, faster speed, higher frequency, and longer service life. The precision is several times higher than that of trapezoidal screw, and even the reciprocating precision can reach about 3 to 5 thousandths. The application range is very wide and more suitable for modern intelligent equipment.

The input mode of the SWLB ball screw elevator:
Both manual and electric are acceptable. The elevator box can be made into various forms such as single input shaft, double shaft extension type, asynchronous motor connection flange, servo motor connection flange, and stepper motor connection flange. The input methods are diverse.

Assembly form:
For the screw lifting type: the screw head can face upward or downward;
For the nut moving type: the nut can face upward or downward.

Screw head:
For the screw lifting type: including cylindrical head, flange head, threaded head, flat head type, etc.; these kinds of heads are relatively common in this model, and can be selected according to actual needs;
For the nut lifting type: there are cylindrical head and threaded head; in the nut lifting type, the cylindrical head is generally more commonly used.

The models of the SWLB ball screw elevator produced by Shanghai Dianmai Transmission include: SJB10, SJB20, SJB21, SJB22, SJB50, SJB51, SJB80, SJB81, SJB100, SJB101, SJB200, SJB201, SJB300. The lifting force can reach 1000KN. However, depending on the difference in speed and stroke, the lifting force will also be different. Specific model selection needs to refer to the stroke, speed, and installation method. You can consult Shanghai Dianmai Transmission.
