Elastic Nuts also known as roll-in spring ball nuts or spring-loaded ball nuts, are specialized fasteners designed for use with aluminum extrusion profiles, particularly those with T-slots. Roll ball elastic nuts are designed with a spring mechanism and a ball bearing system that allows them to be easily inserted into the T-slots of aluminum extrusion profiles. The spring-loaded ball bearing sits in a pocket on the nut and is depressed when the nut is pushed into the slot, allowing it to roll into place. Once in position, the ball bearing snaps back into place, securing the nut within the slot.
Applications
These nuts are widely used in applications where quick assembly, disassembly, and reconfiguration of structures are required:
- Machine Frames: They are used to assemble and secure machine frames and other mechanical structures.
- Workstations and Displays: Commonly used in the construction of modular workstations and exhibition displays.
- Automated Systems: Employed in automated systems and conveyors where adjustable support structures are needed.
- Furniture and Fixtures: Utilized in furniture design for adjustable and modular components.
Material and Finish Options
Roll ball elastic nuts are typically made from high-quality carbon steel, which provides high hardness and a long service life. They may also be constructed from stainless steel or other materials depending on the application requirements. The surface finish often includes nickel plating, zinc plating, or other treatments to enhance rust resistance and performance.
Installation Process
The installation of roll ball elastic nuts is straightforward:
- Alignment: Align the T-slot on the extrusion profile with the path of the nut.
- Insertion: Push the nut into the slot, depressing the spring-loaded ball bearing.
- Seating: Once the nut is fully inserted, the ball bearing snaps back into place, securing the nut within the T-slot.
Advantages
- Quick Assembly: The roll ball elastic nut allows for rapid assembly and disassembly, saving time and effort.
- Adjustability: They provide adjustable positioning along the T-slot, offering flexibility in design and assembly.
- Reusability: The spring-loaded mechanism allows for multiple insertions and removals without loss of performance.
- High Retention: The spring and ball bearing system ensures a secure hold within the T-slot.
