Ultra-compact linear motion solution combining high rigidity and smooth movement in constrained spaces. Features optimized ball recirculation geometry for reduced vibration and a hardened raceway surface (HRC58-62) for extended service life. Pre-loaded carriage eliminates mechanical play while maintaining low friction coefficient (μ<0.005). Compatible with automatic lubrication systems via grease nipple (S10AP suffix indicates pre-greased with ISO VG10 oil).
- High-speed pick-and-place mechanisms in desktop automation
- Z-axis positioning in compact CNC engraving machines
- Optical lens adjustment stages
- Precision syringe pumps for medical devices
- 3D printer extruder carriage systems
Installation guidance:
Mount on machined reference surface with flatness ≤0.02mm/100mm.
Use 0.5-0.8Nm torque for M3 mounting screws. Avoid side-loading during
assembly - maximum permissible angular error: ±0.5°.
