NEFF Ball Screw Drives KGT 1616 & KGT 3260
2Pages

NEFF Ball Screws extended its product range of Ball Screw Drives. For the demand of higher speeds at the same mass moment of interia and less motor capacity there are two new products: KGT1616-P8-3.0 with cylindrical or flanged nut KGT 1640-PI 0-3,0 with cylindrical or flanged nut KGT 3260-PI 0-3,5 with cylindrical or flanged nut. General technical data: The thread profile of NEFF ball screws is produced by cold rolling. Both screw and nut have an arched thread profile. The load angle is 45°. The new ball screw drives are available in accurate classes up to T5 (12pm/300mm). The integrated frontal channel deflection system at the KGT 1616-P8-3.0 is responsible for low noise operation. According to this advantage the 4-start ball screw KGT 1640-PI 0-3 and the 6-start ball screw KGT 3260-PI0-3,5 is characterized at its also low noise cover deflection system. The NEFF ball screws range corresponds to DIN 69051 and the NEFF-Standard. Effective in appropriate quantities nuts can also be delivered in customized designs.
