Trapezoidal nut 50x8 right-hand flanged, bronze

Product Description

Trapezoidal nut 50x8 right-hand flanged, 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 CuSn5Zn5Pb5-C (CC491K), right-hand thread Tr 50x8 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 50x8, 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 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.

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 CuSn5Zn5Pb5-C (CC491K) - 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 holes in the flange allow the nut to be screwed directly to the moving part of the machine, without an intermediate sleeve.

Where are 50x8 trapezoidal nuts used?

50x8 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.
