Footnotes:
1) Including fastening screws or extraction threads
2) Screw tightening torque according to DIN 912, strength class 10.9
3) Note! The fixing holes in the adjacent construction should follow the pitch of the bearing holes
4) The screw countersink of the large L ring opens toward the bearing bore. This area does not support the bearing bore
5) Please consult for high-speed applications
6) Measurement results after internal assembly: measuring speed nconst = 5 min-1; using myonic standard grease and standard quantity; without support ring; bearing friction torque can increase by 2.5 times at limiting speed

Notes
Important Reminders
- The data listed in this table are reference values. Final specifications are subject to the myonic official product catalogue.
- The NGX-SBI series (rotating outer ring) has the same main dimensions, but the internal structure is optimized for rotating outer ring.
- For special configurations or customized designs, please contact the myonic application engineering team.
