Product Description

What this part is:

The GPZ NU311NA is a single-row cylindrical roller bearing of NU design, carried under the GOST designation 32311. It is the 311 size in the medium 03 dimension series: 55 mm bore, 120 mm outside diameter, 29 mm width.

Decoding the designation:

NU — cylindrical roller bearing with two integral ribs on the outer ring and a rib-free inner ring. Non-locating: the shaft moves axially relative to the housing in both directions.

311 — 03 dimension series, bore code 11 = 55 mm.

32311 — GOST designation for the same NU 311 bearing.

Specifications:

Bearing Type: Cylindrical Roller Bearing. Design: NU. Rolling Elements: Cylindrical Roller. Number Of Rows: 1. Bore Diameter: 55 mm. Outside Diameter: 120 mm. Width: 29 mm. Bore Type: Straight. Closure Type: Open. Snap Ring: No. Lubricant: grease or oil.

Dimensions and mounting:

Envelope: 55 x 120 x 29 mm. The inner ring separates from the outer ring and roller assembly, so each ring is mounted independently. The NU design accommodates axial shaft expansion within the bearing.
