Technical catalog with dimensions, torque, axial force, material and application data for RINGFEDER RfN 4061 contraction rings.
The RINGFEDER RfN 4061 contraction rings provide a modern method for creating a mechanical interference fit, compressing an inner cone ring to securely fix a hub to a shaft. They are suitable for high‑speed applications such as gears, pulleys, couplings and flanges.
The catalog lists detailed specifications, including maximum clearance, surface‑finish requirements, torque limits and optional nickel plating, together with calculation guidelines for cube and shaft design. This manual is written in Portuguese.
