Product Highlights
- High-precision miniature ball screw with Ø8 mm shaft — optimized for compact linear motion systems.
- 2 mm lead provides fine, repeatable linear travel for accurate positioning and low backlash.
- Manufactured from GCr15 hardened steel for excellent wear resistance and long service life.
- Accuracy grade C3 — suitable for precision CNC stages, medical devices, optical alignment, and robotics.
- Short total length (93 mm) and thread length (53.5 mm) — perfect for sample builds and small assemblies.
Why choose this ball screw?
This precision ball screw (Ø8 × 2 mm lead) delivers smooth, low-friction linear motion with high repeatability. The GCr15 material and C3 accuracy ensure stable performance in applications requiring tight positioning tolerance. Because it is a ball screw shaft built for miniature actuators and linear guides, it easily integrates with linear bearings, stepper/servo motors and compact nut assemblies.
Typical applications
Precision CNC micro-machines, pick-and-place heads, optical and measurement equipment, medical instruments, laboratory automation, micro-robotics and other systems where compact precision ball screw components are required.
Ordering & customization
Standard part: Ø8mm × 2mm lead, Lthread 53.5mm, Ltotal 93mm, GCr15, C3. Custom lengths, coatings, or integrated nuts can be produced on request. Please contact us with your drawing or assembly requirements for lead/length adjustments, nut type (single/double), preload options, or heat-treatment specs.
Technical notes
- Accuracy C3 refers to axial accuracy tolerance in accordance with common ball screw standards — suitable for many precision applications but not for ultra-high precision where C0/C1 might be required.
- Recommended lubrication and end-support design will extend service life — consult our engineers for bearing selection and installation guidance.
