The specific oil film thickness is defined as the quotient of the oil film thickness and combined roughness of the meshed tooth flanks.
AGMA 925-A03 uses the specific oil film thickness with a wavelength filter cutoff of 2* bH for evaluating the lubricating condition.
The roughness of the tooth flanks must first be measured before this parameter can be determined. The limit from which a surface change is no longer specified as roughness can be specified here.
A typical wavelength filter cutoff is 0.8 mm (L0.8 = 0.8 mm).
