Product Info

The IKO STSI Series Miniature Stroke Rotary Bushing provides ultra-compact guidance for combined rotary and linear motion. With high-precision steel balls, a thin-walled sleeve, and super-finished components, it is ideal for space-limited applications in precision instruments and cleanroom environments.

■ Product Features
- Dual Motion Capability: Enables smooth, synchronized rotary and reciprocating linear motion using cylindrical steel balls within the retainer.
- High-Precision Finish: Heat-treated and super-finished outer sleeve and shaft provide superior stability, accuracy, and wear resistance.
- Ultra-Compact Profile: Thin-walled outer sleeve and miniature components ensure minimal cross-sectional height—perfect for tight mechanical layouts.
- Preloaded Steel Balls: Reduces friction and stick-slip for smooth, stable motion and long-lasting reliability.
- Clean & Lightweight Solution: Compact form factor makes it suitable for delicate, high-precision environments including medical and semiconductor equipment.

■ Specifications
- Motion Types: Simultaneous rotary and linear (reciprocating) motion
