Spiral spring 75-1300-75

extensionsteelcase

NEFF spiral springs reliably protect ball screws and threaded drives from contamination, mechanical stress, and external influences. They help ensure a long service life and consistently reliable operation of linear drives, especially in demanding industrial environments.

Thanks to their flexible design, the spiral springs adapt perfectly to the movement of the lead screw, providing effective protection while allowing for easy integration into existing machine designs. They are an ideal complement to NEFF ball screws and other lead screw solutions.

Your Benefits at a Glance

• Protects the lead screw from dust, chips, and contaminants
• Extends the service life of lead screw drives
• Reduces maintenance requirements and downtime
• Flexible adaptation to linear movements
• Easy installation and integration
• Suitable for demanding industrial operating conditions
• Ideal complement to NEFF lead screw drives
