Product Description
Screw diameter: In the SFKR series, "10" indicates that the nominal diameter of the screw is 10mm. This size determines the overall size of the ball screw and the installation space requirements in the equipment. The small diameter makes it suitable for tiny devices with limited space.
Lead: 02 indicates a lead of 2mm. The lead refers to the distance that the nut moves along the screw axis when the screw rotates once. The small lead means that at the same screw speed, the linear movement of the nut is relatively slow, but more fine displacement control can be achieved, which is suitable for occasions where high precision positioning is required.

Product Display
Positioning accuracy:
Due to the small lead, SFKR1002 products provide excellent positioning accuracy. It can achieve positioning accuracy at the micron level, which is critical in precision equipment. For example, in the lens adjustment mechanism of optical instruments, this high-precision ball screw can precisely control the position of the lens to ensure the accuracy of the optical system.
Repeated positioning accuracy:
Its repeated positioning accuracy is also high, and it can accurately return to the same position after multiple round-trip movements. This is helpful for repetitive actions on automated production lines, such as the precise picking and placing of tiny parts many times during the assembly of micro-electronics.
Axial load:
Although it is a miniature ball screw and the lead is small, it still has a certain axial load capacity. It can withstand axial forces appropriate to its size and is used to push small loads in linear motion. The specific load capacity depends on the screw material, the size and number of balls and other factors. For example, in the nozzle lifting mechanism of a small 3D printer, it can stably carry the weight of the nozzle and achieve precise height adjustment.
Dynamic load and static load:
In terms of dynamic load, because of the small lead design, it can better cope with the changing load situation during the movement. The static load capacity ensures that the ball screw can reliably support the load in the static state, preventing the load from sinking or generating displacement.
Speed range:
Due to the small lead, its linear motion speed is relatively low, but this also makes it smoother at low speeds. In some of the speed requirements are not high, but the motion accuracy and stability requirements of the equipment is excellent. For example, it can provide steady motion during the slow movement of a sample detection platform for a small medical device.
