Air bearing separator rolls – sensitive and tough

 

Retech air bearing separator rolls (ABSR) are specially designed for extreme high speed, heavy-duty processes and high-temperature environments. They operate with very low air consumption, which makes them economical and user-friendly.


Air bearing separator rolls give best results in critical processes such as bulked continues filament (BCF), super-high tenacity yarn for technical application, e.g. industrial yarn and automotive fibres.


For very sensitive yarns requiring lowest inertia, or yarns which make only partial contact, Retech air bearing separators or guiding rolls are the ideal solution. They also solve the problem of insufficient lifetime of standard ball bearing separator rolls.


Good to know: where low inertia, high draw forces combined with high temperatures are demanded, Retech air bearing separator rolls are just the right solution.        

Retech air bearing separator rolls (ABSR) are perfectly designed for extreme high speed, heavy-duty processes and high-temperature environments.
