NU 220 E C3 ZVL bearing

SINGLE-ROW CYLINDRICAL ROLLER BEARINGS, TYPE „NU"
Single-row cylindrical roller bearings transmit high radial loads and at the same time allow high running speeds. They are manufactured in different designs, distinguished mainly by the position of the guide flanges.
TYPE „NU"
The inner ring of the NU design has two guide flanges; the outer ring is without guide flanges.
Bearing dimension identification:
d: inner diameter (mm) of the bearing
D: outer diameter (mm) of the bearing
B: width (mm) of the bearing

Standard suffix codes:
CN – normal radial internal clearance; typically used in combination with one of the letters below, indicating a reduced or shifted clearance range.
C2,C3,C4,C5 – designation indicating radial internal clearance.
EC – Optimised internal design featuring more rollers, possibly larger, and a modified contact between roller end faces and flanges.
J – stamped steel cage
MA,MB,ML,MP,MR – type of machined steel cage.
N – Snap-ring groove in the outer ring. NR — same description + snap ring.
