Trapezoidal nut 26x5 left-hand cylindrical, bronze

Product Description

Trapezoidal nut 26x5 left-hand cylindrical, bronze

This element is always selected together with the screw - without matching size, pitch and thread hand the mechanism will not fit together. Standard DIN 103 / ISO 2901-2904, material Tin bronze CuSn7Zn4Pb7-C (CC493K), left-hand thread Tr 26x5 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

You need a screw Tr 26x5 with the same thread hand (left-hand) and the same pitch - other sizes will not fit together.

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.

What does the symbol Tr 26x5 mean?

The designation "Tr" indicates a trapezoidal thread with a symmetrical 30° profile. The first number is the nominal diameter in mm, the second is the pitch - the distance the nut travels per turn of the screw.

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 are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - a material long used in screw drives because of its favourable sliding friction coefficient.

How is this nut mounted in the mechanism?

The smooth, round outline allows the nut to be seated in a recessed socket, without protruding edges.

Where are 26x5 trapezoidal nuts used?

26x5 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.
