NLGI

The NLGI class (penetration class) divides lubricating greases up into the relevant consistency groups according to DIN 51818.

We differentiate between viscous oils, soft grease, standard grease and solid grease.

The NLGI classes include classes 000 (maximum walk penetration) = 445 to 475) to NLGI 6 (minimum walk penetration = 85 to 115 )
