RHP 7205CTSULP4 super precision angular contact ball bearing in the ISO 02 dimension series. One bearing, universally matchable single. Bore Diameter: 25 mm. Outside Diameter: 52 mm. Width: 15 mm. Rings and balls are carbon chrome bearing steel to SAE 52100, through hardened and heat treated for dimensional stability.
7 — single row angular contact ball bearing.
0 — ISO 02 dimension series.
05 — 25 mm bore code.
C — 15° contact angle.
T — outer-ring-guided laminated phenolic cage.
SU — universally matchable single; ring faces are ground so that any two bearings of this designation clamp up to the light preload value back-to-back or face-to-face, or run in tandem.
L — light preload.
P4 — ISO Class 4, ABEC 7, BS292 grade EP7.
7205X2TAULEP7 — the same bearing in the RHP B-series scheme, where X2 denotes 15°.
2MM205WICRSUL — the same bearing in the Fafnir scheme, where 2MM denotes 15°.
Contact Angle: 15°. Dynamic Load Rating: 16.6 kN. Static Load Rating: 10.2 kN. Limiting Speed: 44,900 rpm oil/air; 27,800 rpm grease, quoted for a single bearing under spring preload. Precision Class: P4 / ABEC 7. Preload: Light (L), 78 N axial preload in a matched pair, axial stiffness 36 N/µm. Cage Material: Laminated phenolic. Cage Type: Machined, outer-ring guided. Maximum Cage Temperature: 120 °C. Closure Type: Open. Unit Quantity: 1 Pc.
Shaft Abutment Diameter: 31 mm. Housing Abutment Diameter: 46 mm minimum, 47 mm maximum. Effective Load Centre: 12.7 mm from the bearing face. Internal Free Volume: 6.2 cm³. Lubrication Jet Pitch Circle Diameter: 35.5 mm. Item Weight: 0.128 kg (0.28 lb).
Cross-references: RHP 7205X2TAULEP7 and Fafnir 2MM205WICRSUL are the carton-printed equivalents of this exact execution. The 7205A5 executions share the 25 x 52 x 15 mm envelope at a 25° contact angle. Paired executions DU, DB, DF and DT and the EL, M and H preload grades are related variants.
15°, shown by the C in the RHP designation, the X2 in 7205X2TAULEP7 and the 2MM in 2MM205WICRSUL.
Dynamic Load Rating 16.6 kN and Static Load Rating 10.2 kN. Limiting Speed 44,900 rpm on oil/air and 27,800 rpm on grease, for a single bearing under spring preload.
SU is a universally matchable single. Any two bearings of this designation clamp up to the light preload value back-to-back or face-to-face, or run in tandem.
