A double-row full-complement cylindrical roller bearing. Bore Diameter: 90 mm. Outside Diameter: 125 mm. Overall Width: 35 mm. Rolling Elements: Cylindrical Roller. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Cage Type: Full complement, no cage. Bearing Material: Chrome steel. Series: RS4900.
NNC — double-row cylindrical roller bearing. Two rows of rollers between a one-piece inner ring and a one-piece outer ring.
V — full complement. The cage is omitted and the roller pockets are filled, which raises the roller count and with it the radial load capacity.
4918 — the 49 section at 90 mm bore, 125 mm outside diameter, 35 mm width.
A 35 mm width on a 90 mm bore and a 125 mm outside diameter is a thin section, so the bearing fits where radial space is short and load is high.
A full complement carries more radial load than a caged bearing of the same envelope. Without a cage to separate them, adjacent rollers touch and their contact surfaces run against each other, so the practical speed range is lower than a caged equivalent.
Bore Diameter: 3.5433 in. Outside Diameter: 4.9213 in. Overall Width: 1.3780 in. Bore Type: Straight, so the inner ring mounts directly on a cylindrical shaft seat. Snap ring included: No.
Unit Quantity: 1 Pc.
The 90 by 125 by 35 mm envelope with a double-row full-complement roller set is the NNC 4918 V size, and the crosses listed are the designations other makers carry for it.
