Permissible speed

The permissible speed is the lower value of:
SKF recommends oil lubrication for bearings with a ring centred cage (designation suffix ML). When these bearings are grease lubricated (→ Adjustments of relubrication intervals due to operating conditions and bearing types, Cylindrical roller bearings), the n dm value is limited to ≤ 250 000 mm/min.
where
dmbearing mean diameter [mm]
= 0,5 (d + D)
nrotational speed [r/min]
Higher speeds are possible with modified bearing designs or with additional heat dissipation from the application. For additional information, contact the SKF application engineering service.
