MICRO is suitable for all BD, BDA, BT 902, 903, 904, 905 rotor spinning machines.

Any rotor cup (currently with 25 microns) from our portfolio can be produced as MICRO.  Send us your inquiry stating  „rotor MICRO“.

• Excellent price/performance ratio
• Matching the lifetime of rotor cup and rotor bearing
• Longer lifetime compare to rotor cups with hard elox

Variants of rotors below bring the possibility to adjust the choice of spin box components both to operational and economical points of view and can be equipped with several different types of rotor bearings.

• PLC 73-1-24 - standard bearing with 12 metal balls designed for 75 000 rpm, 10 mm shaft
• PLC 73-1-51 - innovated type of the bearing with 10 metal balls + 2 ceramic balls with prolonged service life designed for speed up to 80 000 rpm, 10 mm shaft
• PLC 73-1-67 - fully ceramic bearing with prolonged service life designed for speed up to 80 000 rpm, 10 mm shaft
• PLC 72-8-3K - fully ceramic bearing with prolonged service life designed for speed up to 100 000 rpm, 8.9 mm shaft (based on rotor cup A3, 43mm or A4, 40 mm, this type of bearing is recommended to be used with NiDi cups running at max speed 80 000 rpm)
