SKFNU 314 ECPCylindrical Roller Bearing – 70 mm Bore, 150 mm OD, 35 mm Width, NU Design, Polyamide Cage, Separable Rings

Product Description

What this part is:

SKF NU 314 ECP is a single-row cylindrical roller bearing in the NU design, with a glass-fibre reinforced polyamide cage. Bore Diameter: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm. Rolling Elements: Cylindrical Roller. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Cage Material: Polyamide. Cage Type: One-piece window cage, roller guided. Bearing Material: Chrome steel. Lubricant: Grease or oil. Series: NU 3. Base Number: NU 314. Unit Quantity: 1 Pc. Country of Origin: Germany.

Decoding the designation:

NU — two integral ribs on the outer ring and a ribless inner ring, so the roller set runs free along the inner ring raceway and the bearing floats axially in both directions.

3 — ISO dimension series 3, the heavy section. At a 70 mm bore that gives a 150 mm outside diameter in a 35 mm width.

14 — bore code 14, giving 70 mm.

E — the reinforced execution, with a larger roller complement and a higher load rating than the base design.

C — the current SKF internal design for the E-series cylindrical roller range.

P — one-piece window cage in glass-fibre reinforced polyamide.

Specifications:

Dynamic Load Rating: 236,000 N. Static Load Rating: 228,000 N. Expansion Type: non-locating, axially free in both directions.

The NU design leaves the inner ring ribless, so the roller set slides along the inner ring raceway and the bearing takes axial shaft movement in both directions.

Dimensions and mounting:

Bore Diameter: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm. The rings separate: the inner ring mounts on the shaft on its own and the outer ring with its roller and cage assembly mounts in the housing independently. One complete bearing: inner ring plus outer ring with roller and cage assembly.

Compatibility and replacement:

The same bearing is written NU 314 ECP, NU-314-ECP, NU314ECP and NU314.

Cross-Reference 1: FAG NU314-E-XL-TVP2. Cross-Reference 2: NSK NU314ET. Cross-Reference 3: NTN NU314ET2X. Cross-Reference 4: Koyo NU314R. Cross-Reference 5: Nachi NU314EG. Cross-Reference 6: NTN-SNR NU314EG15. Cross-Reference 7: NU314E, the generic ISO form of the reinforced execution. Cross-Reference 8: Timken NU314EMA, machined brass cage.

Every number above shares the 70 x 150 x 35 mm envelope and the NU rib arrangement. The NJ 314 ECP carries one rib on the inner ring and locates the shaft in one direction, and the NUP 314 ECP adds a loose rib ring and locates it in both; both fit the same shaft and housing and change the axial location, so they are related sizes.
