Precision Ground Ball Screw Assemblies

Ball screw thread is made via a precision grinding process.  This provides the highest quality raceway surface for the miniature balls within the ball nut to follow.

This is the highest quality product in all of the miniature ball screws that we offer.  These have a completely machined drive end so you will not have to do any additional machining prior to installation.

Precision Rolled Ball Screw Assemblies

Ball screw thread is made via a precision rolling process.  This provides an good quality raceway surface for the miniature balls within the ball nut to follow.

The rolled screws ends are not machined, just cut to length.  This makes them one of the more economical ball screw products in the miniature ball screw products.

Bi-Directional Ball Screw Assemblies

These are precision ground screws with a right thread on one side and a left hand thread on the other.  Thread lead (or pitch) is the same on either end of the screw.   The ball nuts move in opposite directions of each other.

These are frequently use in gripper, clamping, and centering type applications.  Available thread leads are 1 and 2 mm.

Motorized Ball Screw Assemblies

These are ball screw assemblies with a stepper motor directly integrated with the ball screw shaft.  No coupling is needed allowing for reduced overall assembly length.   The ball nuts move in opposite directions of each other.

These are frequently use in applications when overall length cannot be met with a conventional motor, shaft coupling, and ball screw arrangement.

Custom Ball Screw Assemblies

These are ball screw assemblies that require customization in some form other than the standard preconfigured flanged ball nut catalog offering.  They typically require drawings for screw end machining or utilize special ball nuts.

OEM machine and instrument builders choose these products when other solutions are not applicable.  These usually require longer lead-time for development.
