ALM is known for manufacturing different types of lead screws,like trapezoidal lead screw,ACME screw,metric thread screw and reciprocating screws.To meet customer's application requirements of higher precision and higher smoothness.ALM introduced a top-tier round thread lead screw series.Round threads,also known as Knuckle thread,it is similar to ball screw thread,feature a unique,highly rounded shape with a flank angle of 30°.

 

 

Advantages of round/knuckle thread lead screw

(1)High precision and efficiency: Round lead screw is suitable for higher accuracy and efficiency application.

 

(2)Absolutely smooth running:Compared with trapezoidal screw or ACME screw,round thread leadscrew provides better smooth performance,reduces friction and resistance during movement.

(3)Long service life: The large space between the rounded crests and roots provides space for debris to be shifted to not interfere with the thread,making this form resistant to debris and thread damage.

 

(4)Convincing price/performance ratio:Through continuous technological innovation and production efficiency improvement,our knuckle thread screw is of higher quality and more affordable price,which is favored by customers around the world.
