Lead screws reach linear range of 200mm
Increasing the helix angle on lead screws allows leads to be achieved up to 200mm, that is the captivated nut will travel 200mm in a linear direction for one complete rotation of the screw.
Traditionally, lead screws are supplied with either high helix single or double start thread formats to achieve higher linear speed However, the leads of such screws rarely exceeded 20mm

Customised nuts and attachments for lead screws
Abssac has long supplied cold rolled formed stainless steel lead screws and anti-backlash nut designs, and now offers the facility to have non-standard attachment designs incorporated
Lead screws with multi-start threads allow a low rotational input speed to be converted into a high linear speed with high efficiency.
With this process, Abssac can supply 10, 15 and 20 start threads which increase the helix angle allowing leads to be achieved up to 200mm, that is the captivated nut will travel 200mm in a linear direction for one complete rotation of the screw.
With such high speeds being delivered, the lead screws can be used as an alternative to belt drives or in any application where high acceleration speeds are required.
Additionally, by the nature of its design, the increased amount of threads per screw increases the load capacity of the nut due to there being more contact points on the screw.
Available in diameters from 5 to 36mm, the high speed screws can be a cost effective means of achieving high speed linear travel. Request a free brochure from Abssac ...
