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.

Product Characteristics
Your 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.
