The CONTI FFR Tr 20x4 trapezoidal nut is a precision-engineered solution from CONTI, an Italian manufacturer renowned for high-quality linear drive components. Made from Cu Sn5 Zn5 Pb5-C bronze (UNI EN 1982 - CC491K), this flanged nut delivers excellent strength, wear resistance, and durability — essential for applications with continuous operation and demanding load cycles.

With a Tr 20 x 4 right-hand thread and 1 start, this nut ensures smooth, consistent linear movement, minimizing backlash and maintaining accurate positioning over time. Its flanged shape (Ø55 mm flange, BCD Ø45 – 6xØ6.5) offers secure mounting and added stability, simplifying integration into linear systems.

Measuring 44 mm in length, it is compact enough for constrained assemblies, while still providing reliable load distribution. The open internal profile pairs well with quality lubricants, enhancing performance by reducing friction and extending operational life — making it ideal for lifting systems, actuators, and machinery requiring precise, continuous motion.
