Trapezoidal nut 20x4 right-hand cylindrical, bronze

Product Description

Trapezoidal nut 20x4 right-hand cylindrical, bronze

The accuracy of the thread translates into smooth motion and a long service life of the entire drive system. Standard DIN 103 / ISO 2901-2904, material Tin bronze CuSn7Zn4Pb7-C (CC493K), right-hand thread Tr 20x4 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 20x4, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

Does this nut need lubrication?

Yes - good grease is recommended, because this is a sliding element working under load. Lack of lubrication accelerates thread wear.

How do the material families of trapezoidal nuts differ?

Steel is chosen for fastening joints without sliding motion, bronze for drives with continuous sliding motion (low friction), and brass for lighter applications where moisture resistance matters at a lower cost than bronze.

What does the symbol Tr 20x4 mean?

"Tr" is a symmetrical trapezoidal thread (flank angle 30°). The first number is the outer diameter of the screw in millimetres, the second is the thread pitch, i.e. the linear travel per full turn.

What are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - low tendency to seize when paired with a steel screw, the standard in screw-and-nut drives.

How is this nut mounted in the mechanism?

The cylindrical body is designed to be installed inside a housing or mounting sleeve.

Where are 20x4 trapezoidal nuts used?

20x4 trapezoidal nuts are used in screw jacks, presses, vices, positioning tables, linear axes of CNC machines and tensioning mechanisms - wherever the rotary motion of a screw must be converted into precise, repeatable linear motion.
