item North America is a premier provider of precision ball screws for use as a drive mechanism in linear slides, multi-axis motion and complex material handling devices.

item ball screws feature high precision, high efficiency, high rigidity of the drive system and low mechanical wear.

item ball screws are custom designed for each specific application at no extra cost.

Individual linear components may be easily integrated with all ball screw assemblies.

Low maintenance requirements mean that item ball screws can provide 400-500 service hours before requiring service with lithium based ball bearing grease.

item ball screws can be driven by crank handles, hand wheels, AC/DC motors, stepper & servo motors and hydraulic or pneumatic drive mechanisms.

item ball screw components may be replaced individually.

item ball screws can be easily integrated into all MB Building Kit System profiles and modular components.

item offers a complete line of mechanical drive elements that can be machined to specific requirements. Machining to NEMA flange specifications is available. Ball screw hubs can be re-bored to 17mm or 14mm with a keyway.

item can provide standard design assistance and product delivery in ten working days or less.

Twenty-four hour emergency delivery service is available.

Available Pitch - item ball screws are available in both 20x20 (20mm diameter screw by 20 pitch) and 20x5 (20mm diameter screw by 5 pitch).

Maximum Stroke Length - maximum stroke length for item ball screws is approximately 110 inches or 2762 mm.

Maximum Acceleration - maximum acceleration for item ball screws is up to 5 m/s² depending upon drive methods.

Top Speeds - top speeds for item ball screws are 1m/s (20x20) or 250 mm/s for 20x5 pitch. (P.S. it is not s²)

Thrust Loads - achievable thrust loads are 1000 N.

Rotational Speeds - item ball screws are capable of rotational speeds of 3000 rpm depending upon screw lengths.

Accuracy & Repeatability - depending upon the length of the screw, item ball screws are capable of positional accuracies of less than + .002 inch repeatability.

Screw - item ball screws are precision rolled for maximum strength, durability and value.

Integrated Protection - all item ball screws are protected by an integrated rubber lip seal to prevent dust, debris and other harmful agents from entering the internal ball screw mechanism and motion components.
