Dimension Notation Notes
Footnote explanations:
1) Including fastening screws or extraction threads
2) Screw tightening torque according to DIN 912, strength class 10.9
3) Attention! Fixing holes in adjacent construction should follow the bearing hole pitch
4) Screw counterbores on large L-ring open toward bearing bore. This area does not support bearing bore
5) Please consult for high-speed applications
6) Measurement result after internal assembly: Measurement speed nconst = 5 min-1; using myonic standard grease and standard quantity; without support ring; bearing friction torque may increase up to 2.5x at limiting speed

Important Notes
Important Reminders
- Data in this table is for reference only. Final specifications are subject to the official myonic product catalog and the embedded PDF dimensions table.
- NGS-SBI series (outer ring rotation) has the same main dimensions, but internal structure is optimized for outer ring rotation.
- NGS series has higher load capacity and stiffness compared to NGX, suitable for heavy-duty applications.
- For special configurations or customized designs, please contact the myonic application engineering team.
