Tolerances
With some exceptions the four row cylindrical roller bearings with cylindrical or tapered bore have a dimensional accuracy corresponding to tolerance class P6 and a running accuracy to tolerance class P5.
Six row cylindrical roller bearings are manufactured to tolerance class as Normal specifications.
Radial internal clearance
Four row cylindrical roller bearings with cylindrical and with tapered bore, are produced with C3 or C4 radial internal clearance, while six row cylindrical roller bearings are manufactured with radial internal clearance depending on the application.
On customer's request bearings with different radial internal clearances are available. All cylindrical roller bearings that present helical groove on the inner ring bore are made with C2 radial internal clearance.
