Products Description
DLY 32mm Ball Screws are high-precision linear motion components with an outer diameter of 32mm. They are available in multiple lead options, including 4mm, 5mm, 6mm, 10mm, 32mm, and 64mm, and come in a variety of series such as SFU, DFU, SFI, DFI, SCI, SCM, SFE, and SFA, providing flexible solutions for CNC machines and automation systems.
The 32mm ball screw support is compatible with standard bearings BK25/BF25 and EK25/EF25, ensuring stable and reliable operation under load.
Shaft ends can be customized to connect with different motor coupling methods, including flexible couplings, belt pulleys, and other connection options, making integration with your machinery simple and versatile.
Designed for smooth motion, high load capacity, long service life, and optional preloaded versions to minimize backlash, these 32mm ball screws deliver precise and dependable performance for demanding industrial applications.
