Small but highly effective with 4x greater
radial stability | igus®


TRE.30.050.0.B | smallest chain but with many advantages

completes the TRE.B product range

At last, there is the B version of the smallest TRE chain and it is 4 times more stable.
This version offers not only a stronger radial stop but also a defined torsional stop, whilst featuring the ball-and-socket connecting principle which is designed to cope with high tensile forces. The 'easy' design also makes it possible to insert or remove harnessed cables.
Due to the possibilities of combination with the existing 30-type triflex® R chain series (TRC/TRE/TRL) and the associated mounting brackets, it can also be integrated into existing applications as well as into new applications without any extra effort.

  • New connection principle that is stronger than that of TRE.30.058.0

What is special about the TRE.B version

4x greater radial stability

triflex R B version orange head

The orange-coloured part/head seen here in the picture ensures that the B version has a radial stability which is 4 times greater than that of the standard version.

The stable connection between the chain links can be undone with the help of a disassembling tool.

With the help of the tool, it is possible to separate the chain links from each other by means of specific hand movements.

Due to the size of the TRE.30.050.0.B, it is the only TRE.B version that can be disassembled without a tool.
