RHP7003CTDULP4VSuper-Precision Angular Contact Ball Bearing – 17 mm ID, 35 mm OD, 10 mm Width, Open, 15° Contact Angle, Light Preload, ABEC 7

Product Description

What this part is

RHP 7003CTSULP4V super-precision single-row angular contact ball bearing with a 15° contact angle, light preload, universal ground faces and a machined phenolic cage. Unit Quantity: 1 Pc.

Decoding the designation

7003 — ISO size code. Bore 17 mm, outside diameter 35 mm, width 10 mm, ISO dimension series 10.

CT — Contact angle 15°, laminated phenolic resin cage.

SUL — Single universal bearing, light preload. Inner and outer rings are the same width and flush ground, so any two bearings pair back-to-back, face-to-face or in tandem at the rated preload.

P4 — Precision Class: P4, equivalent to BS292 EP7, ABEC 7 and ISO Class 4.

Specifications

Bore Diameter: 17 mm. Outside Diameter: 35 mm. Overall Width: 10 mm. Contact Angle: 15°. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: carbon chrome bearing steel to SAE 52100, through hardened and heat treated. Cage Material: laminated phenolic resin. Cage Type: machined, outer-ring guided. Series: 7000. Base Number: 7003. Preload: light. Precision Class: P4. Running Accuracy – Radial And Axial Runout: P4. Lubricant: grease or oil. Item Weight: 0.040 kg (0.09 lb).

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.
