Trapezoidal nut 12x2 right-hand flanged, bronze

Product Description

Trapezoidal nut 12x2 right-hand flanged, bronze

The accuracy of the thread translates into smooth motion and a long service life of the entire drive system. Material: Tin bronze CuSn5Zn5Pb5-C (CC491K). Right-hand thread Tr 12x2, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 12x2, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

What does the symbol Tr 12x2 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 CuSn5Zn5Pb5-C (CC491K) - good sliding properties and a low coefficient of friction in the thread, typical of nuts working in motion.

How is this nut mounted in the mechanism?

The flange with mounting holes allows quick, rigid fixing to the body without an additional housing.

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.

Where are 12x2 trapezoidal nuts used?

12x2 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.
