Uses can equest an E44 configuation, which inclues both lubication holes an a machine lubication goove on the outsie suface of the oute ing. Types of beaings inclue the NNU type, which featues ouble ibbe oute ings, an the NN type, which featues excellently gease ischage uing the initial unning-in peio, an helps pomote steay oil flow thoughout the beaing. Fo thin section type beaings, the naowe NN39 seies is moe suitable than the wie NN49 seies ue to less heat geneation an geate olle stability. Machine bass cages ae most common with cylinical olle beaings.
