Ground Ball Screw SFNU

1. Precision: Ground Ball Screws are manufactured and processed with high precision, and the surfaces of the screw and nut are ground to ensure very accurate dimensions and smooth motion.
2. Ball Drive: The threaded grooves on the screw are lined with balls, which roll inside the threads as the screw rotates. This rolling drive reduces friction and increases efficiency and accuracy.
3. High Efficiency: Compared to other linear motion devices, the rolling contact method of Grinding Ball Screws reduces energy loss and therefore provides high efficiency.
4. Precise Positioning: Because of their high accuracy and controlled motion, Grinding Ball Screws are often used in applications that require precise positioning and repetitive motion, such as CNC machine tools, automation equipment, precision instruments, etc.
5. Various specifications: Grinding Ball Screws exist in a variety of specifications and sizes to suit the needs of different applications, such as variations in diameter, lead length and load capacity.

Product Details

Product description

Grinding Ball Screws are mechanical devices designed to convert rotary motion into linear motion. The basic elements of a Ball Screw include a nut and screw with helical grooves and ball bearings. The balls move in a continuous path between the nut, screw and groove, coordinated by the rotation of the screw or nut. They follow a trajectory within the ball return system of the nut, moving from an initial point to an end point and then returning to the starting position. Wipers are strategically located on either side of the nut to act as a shield against debris, which can shorten the life of the ballscrew assembly.

Application

Precision ground Ball Screws find their optimum application where a high degree of travel accuracy cannot be compromised. Stroke accuracy is defined as the deviation, expressed as the measured lead minus the specified lead. Specifically, achieving dimensional tolerances and ensuring repeatability is critical in machining operations such as metal cutting and grinding. In addition to machine tools, some ideal applications for precision ballscrews include the replacement of training equipment (fleet training, flight simulators), simulation technology and hydraulics on motion platforms.
