Product Description

What this part is

RHP 7203CTSULP4 super-precision single-row angular contact ball bearing, ISO dimension series 02. Bore Diameter: 17 mm. Outside Diameter: 40 mm. Overall Width: 12 mm. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Preload: Light. Cage Material: Phenolic. Cage Type: Machined, outer-ring guided. Closure Type: Open. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Bearing Material: Carbon chrome bearing steel, through hardened. Maximum operating temperature for the laminated phenolic cage: 120 °C.

Decoding the designation

7 — single-row angular contact ball bearing.

2 — RHP dimension series 2, ISO series 02. A heavier section than the 70-series at the same bore, carrying a higher load rating.

03 — bore code 03, 17 mm bore.

C — 15° contact angle.

T — laminated phenolic resin cage, outer-ring guided.

SU — single universal. Inner and outer rings are the same width and the faces are ground at manufacture, so two bearings mount back-to-back, face-to-face or in tandem at the designed preload with plain parallel spacers.

L — light preload. Mounted as a back-to-back pair this gives an axial preload of 49 N and an axial stiffness of 25 N/µm.

P4 — ISO Class 4, ABEC 7, British Standard EP7.

What these specs mean in practice

Dynamic Load Rating: 10,900 N. Static Load Rating: 5,850 N. Limiting Speed: 36,400 rpm grease; 58,800 rpm oil. The 02-series section carries 65 percent more dynamic load than the 70-series bearing of the same 17 mm bore, trading some speed capability for it. Lubricant: grease or oil.

Mounting data

Inner ring abutment diameter d1 min: 22 mm. Outer ring abutment diameter D1 max: 35 mm. Outer ring seating diameter D2 max: 37.5 mm. Chamfer dimension r min: 0.6 mm. Chamfer dimension r1 min: 0.3 mm. Effective load centre a: 9.8 mm. Internal free volume: 3.1 cm³. PCD of lubrication jets: 25.9 mm. Item Weight: 0.065 kg (0.14 lb) per bearing.

Quantity and configuration

Unit Quantity: 1 Pc. Mounting Arrangement: Universal single. Universal face control means two of these stack into a DB, DF or DT pair at light preload without custom-width spacers.
