MOTOR MOUNTING TYPE V6 with radial loads and adequated bearing type

[ELEC07]

Hello everyone;
we have a 37kw 380v 1480 rpm/min ATB three phase motor drive an air cooler fan through a VFD converter the motor is V6 Mounting type and have a radial coupling with pulley and belt to the fan, we have bought a new motor HEMLKE DOR225S-04-1G to replace the old ATB one, with almoust the same technical caracteristics,our probleme is about the mounting type of this new motor which is according to the constructor is B3 and can be used as V6 Mounting type (type of mounting is not specified in the motor data sheet SEE JOINTED images)

Another point about the bearing type ;the old atb motor have in DE side an NU 313 ECJ cylindrical roller bearing and in NDE side a 6313 C3 ball Bearing and some rings as shoke adsorber on both side of the shaft but the new HEMLKE when we opened it we found the both side (DE NDE) have a 6313 C3 ball bearing without any shoke adsorber (see images of HEMLEK MOTOR)
can any one help us to confirm that this HELMKE Motors can be mounted on V6 position and if the Ball bearing type can be used on radial load and if possible to give us an idea about how to check mounting type of motor and the adiquated bearing type.
Thank you for taking time to read my poste I appreciate any reply from you
All the best.

Ball bearings are not designed to take full load radially. Change the DE bearing to roller bearing after checking the NDE ball bearing is locating bearing.

That looks like a grease seal rather than a shock absorber.
