Dimension Markings

AXRY-NGX/-EX dimension drawing (section A-A, end faces B-B/C-C/D-D, and lubrication/positioning bore details)
AXRY-NGX/-EX dimension markings: section A-A, end faces B-B/C-C/D-D, plus lubrication bore (B-B*) and positioning bore (E-E, NGX only) details.
*For axial lubrication, remove the screw plug and close the radial lubrication bore. Source: myonic official catalogue EMO 2025.

1) Including fastening screws or extraction thread.

2) Tightening torque for screws acc. DIN 912, strength class 10.9.

3) Attention! For fixing holes in the adjacent construction, observe the pitch of the bearing bores.

4) Screw counterbores in large L-ring open to bearing bore. Bearing inside diameter is not supported in this area.

5) Please enquire in case of high speed applications.

6) Result after in-house assembly: measuring speed nconst = 5 min-1; with myonic standard grease and standard amount; without supporting ring; bearing frictional torque can increase by a factor of 2.5 towards the limiting speed value.
