Minimum load

For additional information
→ Requisite minimum load

Frm = 0,007 C0

Oil lubricated bearings:

n/nr ≤ 0,3 → Frm = 0,002 C0


0,3 < n/nr ≤ 2 →

Perform calculations

Frm = 0,01 C0

Perform calculations
When starting up at low temperatures or when the lubricant is highly viscous, greater minimum loads than Frm = 0,007 C0 and 0,01 C0, respectively, may be required.

P = Fr
Equivalent static bearing load

For additional information
→ Equivalent static load
P0 = Fr
