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.
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.
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.
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.
Same NU 311 envelope as SKF NU 311, FAG NU311, NSK NU311, NTN NU311 and Koyo NU311, and GOST 32311.
