Trapezoidal nut 44x7 right-hand cylindrical, bronze

Product Description

Trapezoidal nut 44x7 right-hand cylindrical, bronze

A trapezoidal nut is the counterpart of the screw: the stationary (or rotating) part of the system that converts rotation into linear travel. Material: Tin bronze CuSn7Zn4Pb7-C (CC493K). Right-hand thread Tr 44x7, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 44x7, the same thread hand (right-hand) - nothing else needs to be checked.

Does a standard trapezoidal nut have backlash in the thread?

Yes, some backlash results from the manufacturing tolerance of the thread - this is normal. If you need zero backlash (e.g. for precise positioning), anti-backlash nuts are used, which are a different product from a standard nut.

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.

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 are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - 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 cylindrical body is designed to be installed inside a housing or mounting sleeve.

Where are 44x7 trapezoidal nuts used?

Typical applications of 44x7 nuts are: presses and screw jacks, machine vices, height adjustment mechanisms, sliding tables and axis drives in machine tools - wherever precise conversion of rotary into linear motion matters.
