Lead & Acme Screw Services

Lead screws or acme lead screws are another specialty at IBR. Acme is a 29° thread form commonly used for lead screws. We engineer and manufacture and repair both inch and metric lead screw assemblies in right and left hand versions.

They are used in lower cycle applications that are not mission critical regarding the product life, and when cost is an important consideration. We offer precision ground screws for higher accuracy and longer life. We manufacture single and multiple starts for most alloy and stainless steel acme lead screws.

IBR can either reverse engineer your lead screw and nut from your original sample and make a new lead screw assembly, or we can regrind your lead screw and make a new lead nut to fit. Contact IBR and let us ensure that you receive quality product.

What We Need From You:

Please provide us these four variables to determine the correct acme screw or lead screw for your application:

• Load-measured in pounds or newtons.
• Speed-measured in inches or millimeters per minute.
• Length-distance between bearings measured in inches or millimeters.
• End Fixity-refers to the method by which the ends of the screw are supported. The three basic types of end fixity are: Free-no support; Simple-shaft supported at a single point; Fixed-shaft rigidly restrained against axial rotation.
