What are the advantages of using special-shaped nuts in elevator door sliders?

1. Strong anti-loosening function:
Special-shaped nuts are usually designed in non-standard shapes, such as hexagonal, square or with anti-slip teeth. For instance, standard nuts may be easily loosened during the prolonged opening and closing of elevator doors owing to frequent mechanical vibration, whereas specially shaped nuts can offer a stronger self-locking function, lessen the need for frequent tightening, and increase the dependability of the door sliding system.

2. Enhanced fixing effect:
Elevator door sliders must slide smoothly on the guide rails and maintain stable alignment. The non-circular design of special-shaped nuts can provide a larger contact area than regular nuts, increasing the friction between fasteners and sliders or brackets. Special-shaped nuts have an improved fixing effect that helps keep the slider's exact position and lowers the possibility of offset or poor sliding.

3. Simplified installation and disassembly:
Special-shaped nuts' form design typically eliminates the need for complicated instruments. Special-shaped nuts can speed up the replacement and adjustment of elevator door sliders, particularly in tight locations or for challenging operations. This improves the efficiency of maintenance work and reduces labor costs and time spent.

4. Resistance to wear and corrosion:
Materials like brass, stainless steel, or galvanized steel are typically used to create special-shaped nuts. Elevators can be impacted by elements like dust or dampness and are typically found indoors or underground. Special-shaped nuts' ability to withstand corrosion can increase their service life and lessen the way that rust or wear-related performance degradation affects sliders.

5. Customized design to meet special needs:
Special-shaped nuts can be made to order in accordance with the unique specifications of elevator door sliders and optimized in accordance with various loads, dimensions, installation locations, or functional needs. Sliders for elevator doors may need to adjust to fit various sized and shaped door bodies. Special-shaped nuts that are custom-designed can satisfy these particular requirements and guarantee that nuts and screws, sliders, fixing brackets, connecting brackets, and other parts are perfectly

6. Reduce the requirements for installation space:
Nuts with unique shapes may take on thin or miniature patterns. Typically, elevator door systems have a limited amount of space. Special-shaped nuts are small enough to be inserted properly in a compact construction without interfering with slider installation or elevator door operation, all the while providing adequate fastening strength.

7. Lightweight yet high strength:
Materials with high strength but low weight, such as titanium or aluminum alloy, can be used to create specially designed nuts that are both lightweight and sufficiently strong.

8. Anti-theft and anti-misoperation design:
Certain nuts with unique shapes are made to be anti-theft or anti-misoperation structures; these nuts typically come with unique shapes and equipment. This design contributes to the long-term safe functioning of the elevator door, prevents unauthorized disassembly or misoperation, and enhances the safety of the elevator door slider system.
