Family specifications and selection conditions
| Product description | SKF filament wound straight (cylindrical) bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads. The composite material is specially developed to accommodate heavy loads, impact loads and vibrations. The bushings are also less sensitive to misalignment and have excellent dry sliding characteristics. |
|---|---|
| Manufacturer features | Maintenance-free operation • Very good frictional properties • High load carrying capacity • Excellent corrosion resistance • Electrically insulating |
