Hundreds of precision ball screw different designs to meet virtually any performance criteria.
Our ball screws can be supplied completely machined and assembled with nuts, flanges, wipers, and EZZE-MOUNTS. Ball nuts are offered in standard and preloaded designs.
Ball Screw Advantages
Ball screws offer a highly efficient means of converting rotary motion to linear motion. Precision ball screws have several bearing balls that transfer the load between the nut and screw.
Ball screws are cataloged by screw thread accuracy: standard rolled, precision rolled and ground.
Improves speed, force, and duty cycle
Longer and predictable life cycle
Requires less motor power
Heavier loads
Greater accuracy
High efficiency (less friction)

Ball Screw – Inch Standard Accuracy (SRT)
Standard Rolled Thread Ball Screw (commercial or transport type)
Offer the low friction advantage of antifriction screws at lower cost. They are capable of higher speeds and longer predictable life when compared to similar acme type lead screws.
Miniature Ball Screw – Metric
Small Diameter Ball Screws
6mm – 14mm Diameter
For decades, Nook has produced custom small diameter ball screws and nuts for the aerospace and medical industries; these standard metric miniatures are the result of that experience. Available in alloy or stainless steel, small diameter screws provide engineers a globally accepted product for smaller footprint applications that demand high accuracy, repeatability, and durability.

Ball Screw – Inch Precision Accuracy (XPR)
Precision Rolled Thread Ball Screw
Offered with leads of 0.200” to 0.500” depending on diameter. Nook uses the latest in CNC thread rolling technology and state of the art CNC induction heat treatment to manufacture a rolled screw with accuracy approaching precision ground at a substantially lower cost.
They fill the need for applications that don’t warrant the expense for ground screws but still require more precise positioning than that offered by commercial grade screws.
Ball Screw – Inch Standard Accuracy (SGT)
Standard Ground Thread Ball Screw
Ground from high carbon alloy steel that has been induction heat treated to a depth greater than the thread. Ground ball screws are used for applications that require smooth operation, precise positioning, and repeatability.
Ball Screw – Metric Standard Accuracy (MRT)
Metric Rolled Thread Ball Screw
Feature precision ball nuts that are an economical, high-performance alternative to ground thread ball screw assemblies. MRT Rolled Ball Screws are manufactured under tightly controlled conditions in the rolling process. Uniform heat treatment is monitored by temperature sensors to ensure high quality and accurate lead.
Ball Screw – Metric Precision Accuracy (PMT)
Precision Rolled Ball Screw
Feature precision ground preloaded ball nuts that are an economical, high-performance alternative to ground thread ball screw assemblies. They are manufactured under tightly controlled conditions in the rolling process. Uniform heat treatment is monitored by temperature sensors to ensure high quality and accurate lead.
Ball Screw – Precision Metric Ball Screw (PMBS™)
Precision Metric Ball Screw Assemblies
Provide very high accuracy at reduced costs. High-lead precision rolled ball screws achieve maximum travel rates with repeatable positioning accuracy. All ball nuts are precision ground and engineered to operate with precision rolled ball screws or precision ground (T3) ball screws.
