Trapezoidal nut 14x3 left-hand cylindrical, bronze

Product Description

Trapezoidal nut 14x3 left-hand cylindrical, bronze

It is the basic element of every screw-and-nut drive - it converts the rotary motion of the screw into the linear motion of the mechanism. Standard DIN 103 / ISO 2901-2904, material Tin bronze CuSn7Zn4Pb7-C (CC493K), left-hand thread Tr 14x3 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 14x3, left-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

How can you tell that a trapezoidal nut is worn?

The most common sign is increasing backlash between the screw and the nut - noticeable jerking when the direction of motion changes. This means the nut thread has worn and needs to be replaced.

What does the symbol Tr 14x3 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.

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.

What are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - it dampens microscopic irregularities of the thread well, which extends the service life of the mating screw.

How is this nut mounted in the mechanism?

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

Where are 14x3 trapezoidal nuts used?

14x3 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.
