Structural Features

The nut body is typically made of high-strength alloy steel or engineered plastic composites.
NSFUL: Standard flanged, left hand threaded nuts with internal ball recirculation, suitable for standard loads and compact installations.
NSFNUL: Extended or special flanged, left-hand nuts with increased load capacity, suitable for high-load or long-stroke applications.

Symbol Meaning

High-precision transmission: Internal ball recirculation design achieves low friction, high efficiency, and stable positioning.
High load capacity: Suitable for medium to high load transmission applications.
Preload design: Eliminates backlash, maintaining rigidity and precision.
Diverse structures: NSFUL lead screw nut offers a standard flange type, while NSFNUL offers extended or special flange designs to meet diverse installation requirements.
Widely applicable: Suitable for CNC machine tools, automated production lines, double-nut transmission systems, and mechanical synchronizers.

Internal Circulation

The circulation mode of the left hand threaded nuts can be divided into internal circulation, external circulation, end plug circulation, etc. according to the circulation mode of the steel ball. Each circulation mode has different advantages and disadvantages and can be selected according to needs.
