Overview

• High-quality RINGFEDER® Locking Elements of the RfN 8006 series are used for friction-locked shaft-hub connections without screws. They are completely wear- and maintenance-free, extremely compact and flexible to deploy, easy to assemble and disassemble and guarantee users maximum reliability and precision. Our locking elements are available to users with an inner diameter from 6 to 1,000 millimetres as well as in slit and solid types. They are particularly suitable for the failsafe transmission of low to medium axial loads and torques.
• Benefits
• Customised application – By varying the number of Locking Elements, size and quantity of clamping screws, the connection can be adapted to fit most applications concerning surface pressures, materials, hub/shaft dimensions and available mounting space.
• Transmission of high loads – To increase the transmissible torque and axial forces up to 4 Locking Elements can be used in series.
• Maximum reliability – No matter whether the connection is subjected to static, pulsating, dynamic or intermittent loads.
• Simple manufacture – Shaft and hub are designed without keyway. Apart from this, relatively large tolerances are admissible.
• Easy adjustability – Locking Elements work without positive connection. So they can be adjusted at any place to any position by following the simple installation and removal instructions.
• Backlash-free – The locking element connection is a mechanical shrink fit and will not wear or loosen in service provided that the maximum transmissible values for the connection are not exceeded.
• High fatigue strength under alternating torsional stresses – As neither the shaft nor the hub have grooves the notch effect is minimized and a higher polar section modulus is given, enabling the use of smaller diameters.
• Simple installation – In comparison to cross-press fits temperature treatments and fitting are eliminated. Screws have to be tightened with standard tools.
• Easy removal – Locking Elements are self releasing no additional measures or auxiliary equipment is required.
• Wear and maintenance-free – Unlimited lifetime if designed and used correctly.
