Country of Origin: United Kingdom.

Decoding the designation

Contact Angle: 15°. Cage Material: Phenolic. Cage Type: Outer ring guided. Precision Class: ABEC 7 / P4. Preload: Medium. Mounting Arrangement: Single universally ground. Internal Clearance: N/A. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. The Fafnir cross-reference on the same carton, 2MM9103WI-DUM, confirms the same 15° angle. Searchable forms of the part number include 7003CTSUMP4V, 7003-C-T-SUM-P4V, 7003 C T SUM P4V and 7003 C T DUM P4V.

What these specs mean in practice

Dynamic Load Rating: 8.35 kN (1,877 lbf). Static Load Rating: 3.80 kN (854 lbf). Permissible Axial Load: 2.85 kN. Limiting Speed, grease: 44,300 rpm. Limiting Speed, oil or oil-air: 67,400 rpm. Effective Load Centre: 8.5 mm. Preload Force: 69 N at medium preload, giving 31 N/µm axial rigidity in a back-to-back or face-to-face pair. A 15° contact angle carries more radial load and runs faster than a 25° or 30° angle. The phenolic outer-ring-guided cage holds a stable rotation at high speed and is rated to 120 °C. Item Weight: 0.039 kg (0.086 lb). Recommended Grease Quantity: 0.22 g per bearing.

Quantity and configuration

Unit Quantity: 1 Pc. A single universally ground bearing at medium preload, so it mounts back-to-back, face-to-face or in tandem against another bearing of the same designation and preload class. The carton also carries the duplex form of the number, 7003 C T DUM P4V, recorded here as an MPN variant.

Fitting notes

Shaft Abutment Diameter: 19.5 mm minimum. Housing Abutment Diameter: 32.5 mm maximum, with a 33.8 mm maximum second housing abutment. Bearing Chamfer: 0.3 mm minimum at the bore, 0.15 mm minimum at the front face. Permissible Shaft or Housing Fillet Radius: 0.3 mm maximum, and 0.15 mm maximum at the front face. Calculation factor f0: 14.5.
