Product Description

Product Overview

URB NU2216EMAC3 single row cylindrical roller bearing. Bearing Type: Cylindrical Roller Bearing. Series: NU22. Model: NU 2216 EMAC3. MPN: NU2216EMAC3. Part Number: NU2216EMAC3. Brand: URB.

Dimensional Data

Bore Diameter: 80 mm. Outside Diameter: 140 mm. Width: 33 mm. The NU22 series carries a wider section than the equivalent NU2 bearing at the same bore and outside diameter, which raises radial capacity for the same shaft and housing envelope.

Internal Construction

Number Of Rows: 1. Rolling Elements: Cylindrical Roller. Bore Type: Straight. Seal Type: Open. Bearing Material: Bearing Steel. The NU form places both integral guide flanges on the outer ring and leaves the inner ring flangeless, so the roller set can float axially relative to the inner ring.

Locating Behaviour

The flangeless inner ring makes this a non-locating position bearing. Shaft growth from thermal expansion is taken up inside the bearing by axial movement of the roller complement along the inner raceway, so no axial load is transmitted through the bearing to the housing.

Fit and Clearance

Internal Clearance: C3. C3 is a radial clearance group larger than standard, sized for tighter shaft interference fits, higher operating temperature at the inner ring, or both.

Classification

Harmonization Code: 8482.50.00. Material: Bearing Steel.
