 1. NUP2310ECP Dimensions

• Bore: 50 mm
• Outer diameter: 110 mm
• Width: 40 mm
• Inner ring raceway diameter: 65 mm
• Chamfer: 2 mm (min)
• Weight: 1.76 kg

2. Load & Speed Ratings

• Basic dynamic load rating: 186 kN
• Basic static load rating: 186 kN
• Fatigue load limit: 24.5 kN
• Reference speed: 6700 r/min
• Limiting speed: 8000 r/min

• NUP: Single-row cylindrical roller bearing, outer ring with two ribs; inner ring has one fixed rib + one loose rib. It can locate the shaft in both axial directions
• EC: Optimized internal design, improved roller-end contact, higher load capacity

• P: Glass-fiber reinforced PA66 polyamide cage, roller-centred

4. Main Characteristics

1). Separable structure: Inner ring assembly (rollers + cage + loose rib) can be separated from outer ring. Easy mounting and dismounting.

2). High radial load capacity: Designed for heavy radial loads; can carry bidirectional axial loads for shaft positioning.

3). Open type, no seals: Requires separate lubrication and sealing arrangement.

4). Radial clearance: CN (normal clearance). Tolerance class P0 standard.

5). Low friction, good high-speed performance: Suitable for continuous running under heavy radial load.

6). Temperature range: -30 ℃ ~ +120 ℃ (PA66 cage).

5. NUP2310ECP Typical Applications

1). Industrial gearboxes/reducers

Suitable for helical gear reducers, conveyor gear units and mixer gearboxes. It bears heavy radial load from gear meshing and realizes bidirectional axial positioning of the gear shaft.

2). Large industrial electric motors & generators

Used for the main shaft of high-power AC motors and standby generators. The polyamide cage supports medium-high speed operation, and the separable structure simplifies motor assembly.

3). Centrifugal pumps and screw air compressors

Bear radial force from the impeller or rotor, absorb moderate axial thrust, widely applied in water, oil and process pumps as well as industrial screw compressors.

4). Machine tool transmission shafts

For lathe headstock and gear hobbing machine drive shafts. It provides high rotational rigidity and stable running precision.
