Decoding the designation

Contact Angle: 15°. Cage Material: laminated phenolic resin. Cage Type: machined, outer-ring guided. Preload: light. Precision Class: P4, equivalent to BS292 EP7, ABEC 7 and ISO Class 4. Running Accuracy – Radial And Axial Runout: P4. Searchable forms of the number: 7003CTSULP4V, 7003CTDULP4V, 7003-C-T-DUL-P4V, 7003 C T DUL P4V, 7003C.

Load ratings and speed

Dynamic Load Rating: 6.6 kN (1,484 lbf). Static Load Rating: 3.8 kN (854 lbf). Limiting Speed: 64,100 rev/min on oil/air lubrication and 39,600 rev/min on grease. Effective load centre: 8.5 mm. Maximum Operating Temperature: 120 °C.

What these specs mean in practice

A 15° contact angle favours speed and radial rigidity over axial capacity, which is what a high-speed grinding or milling spindle wants. Light preload develops 29 N of axial preload and 21 N/µm of axial stiffness in a back-to-back pair. Universal face control means the inner and outer rings are the same width and flush ground, so any two of these bearings clamp together back-to-back or face-to-face at the rated preload with no custom spacer, and share load equally in tandem. P4 accuracy holds inner ring radial runout to 2.5 µm.

Mounting data

Shaft abutment diameter d1 min: 19.5 mm. Housing abutment diameter D1 max: 32.5 mm. Housing abutment D2 max: 33.8 mm. Bearing fillet radius r min: 0.3 mm. Fillet radius r1 min: 0.15 mm. Internal free volume: 1.9 cm³. Pitch circle diameter for lubrication jets: 23.5 mm. Lubricant: grease or oil.

Quantity and configuration

Unit Quantity: 1 Pc. Internal Clearance: N/A. The bearing is preload-set at manufacture rather than clearance-set, so no radial clearance class applies.

Interchange guidance

Same-envelope 15° super-precision executions in other schemes: SKF 7003 CD/P4A, Fafnir 2MM9103WI and NSK 7003CTRSU. A 7003A5 or 7003E in the same 17 x 35 x 10 mm envelope carries a 25° contact angle, which makes it a related size rather than a substitution.
