The NSK W2505SA-4P-C5Z Ball Screw is a high-quality linear motion component designed for CNC applications. This ball screw features a lead of 19mm, which means it moves 19mm for each full revolution of the nut. The screw diameter is 25mm, and it comes with four threads per inch (4P) for precise positioning and movement.
The ball screw is made of high-strength steel, ensuring durability and resistance to wear and tear. The surface of the screw is treated with NSK's proprietary C5Z hard coating, which provides excellent load carrying capacity, low friction, and high running accuracy. This coating also increases the screw's resistance to corrosion and wear, ensuring long-term reliability even in harsh environments.
The NSK W2505SA-4P-C5Z Ball Screw is designed to operate at high speeds and high loads. It has a high stiffness-to-weight ratio, which means it can deliver smooth and accurate motion even under heavy loads. The screw is also equipped with self-lubricating bearings, which reduce friction, increase efficiency, and reduce the need for regular maintenance.
The NSK W2505SA-4P-C5Z Ball Screw is easy to install and integrate into CNC machines. It comes with a high-precision nut that provides smooth and accurate motion, and it is compatible with a wide range of linear guides and actuators. The screw also features a square-shaped shaft, which makes it easy to mount and align with other components in the machine.
Overall, the NSK W2505SA-4P-C5Z Ball Screw is a high-performance, high-quality linear motion component that is ideal for CNC applications. Its advanced coating, high stiffness-to-weight ratio, and self-lubricating bearings ensure smooth, accurate, and reliable motion even under heavy loads. Its easy installation and compatibility with a wide range of components make it a versatile and flexible choice for many CNC applications.
