Guide Bushings
Precision Guidance with Adjustable Play
Achieve maximum precision and efficiency with Spieth guide bushings—designed for round guidance and clamping with adjustable play. Leveraging the proven Spieth principle, these innovative components open up new possibilities for high-power-density, dynamically stressed machine designs.
Key Benefits
- Adjustable Play | Fine-tune guiding tolerances during assembly to compensate for geometric errors and operational influences like heat.
- ISO-Compatible | Surrounding parts can be designed with standard ISO tolerances, simplifying manufacturing.
- Service-Friendly | Easy to adjust and readjust for long-term operational accuracy and minimal downtime.
- High Versatility | Supports both linear and simultaneous rotary movements with high acceleration capabilities.
Applications
Spieth guide bushings are the preferred choice in mechanical engineering and fixture construction where precise, vibration-damped plain bearing guidance is essential. Ideal for:
- Guiding Racks and Round Saddle Slideways
- Tailstock Sleeves and Press Slides
- Machine Tool Spindles
- Sleeve or Column Guidance on Machine Tools
- Applications Requiring Zero Play After Movement
- Frequent Clamping and Releasing Cycles
