Precision lead screw has the advantage of a work hardened surface on which the load bearing nut will travel.
The Abssac precision lead screw comes in acme or trapezoidal thread formats.
Lead screws that are cold rolled formed have the advantage of a work hardened surface on which the load bearing nut will travel.
Starting with a pre-ground bar stock, the thread form is gradually rolled into the material with increasing pressure ensuring precise material deformation along the thread form as it is worked.
By repeating this process, the screw stock work hardens into a smooth, polished like finish with the desired diameter and lead as the finished product.
The smooth acme screw provides a high efficiency, drag reducing surface which is suitable for the range of associated plastic and bronze nuts.
In particular, the active cam nut which handles loads above the normal ratings of a normal plastic nut without loss of its antibacklash features works well with this product.
Supplied in stainless steel to a precision lead accuracy or as it is sometimes termed, pitch error, of 0.05mm per 300mm of linear travel means the lead screws can be used within high accuracy linear applications.
