RINGFEDER CENTRAL LOCK NUT RFN 7090 SST
DESCRIPTION: Ultra-compact, lightweight, cost-efficient: High-quality locking assemblies with central nut from RINGFEDER® are the quick and easy to handle solution for frictional, absolutely backlash-free connections of position-sensitive drive components. They are suitable for use with grooved as well as grooveless shafts and have excellent concentricity properties thanks to their self-centering. Due to the optimal ratio of bore to outside diameter, they are particularly suited for mounting on thin-walled components and in confined spaces. In addition, the low mass moment of inertia and the minimal weight ensure optimum dynamic behaviour.
SPECIFICATIONS
Locking Assembly RfN 7090 with central nut
Precise axial and radial positioning of the components. Easy to connect and to release – no seizures along the shaft. Perfect for engaged connections. Excellent concentricity and radial run.
