RHP 7005CTDULP3 is a super precision angular contact ball bearing set: a universally ground matched duplex pair of two single-row bearings. Bore: 25 mm. Outside Diameter: 47 mm. Width: 12 mm per bearing. Contact Angle: 15°. Preload: Light. Unit Quantity: 2 Pcs. Manufacturer status: RHP super precision production passed to NSK.
7005 — ISO series 10, bore code 05, giving 25 x 47 x 12 mm.
C — 15° contact angle.
T — laminated phenolic resin cage, outer-ring guided, rated to 120 °C.
DU — duplex universal matched pair, universally face-controlled so the pair mounts back-to-back, face-to-face or in tandem at the specified preload with no measured spacers.
L — light preload.
P3 — intermediate grade: ISO Class 4 dimensional accuracy with ISO Class 2 running accuracy.
Dynamic Load Rating: 11,700 N. Static Load Rating: 7,400 N. Limiting Speed: 47,500 rpm oil/air; 29,300 rpm grease. Axial Preload: 59 N, light preload. Axial Stiffness: 32 N per micrometre, light preload. Running Accuracy: Kia 2.5 µm, Kea 2.5 µm. Precision Class: P3. Cage Material: Laminated phenolic resin. Closure Type: Open. Bore Type: Straight. Rolling Elements: Ball. Number Of Rows: 1 per bearing. Bearing Material: Carbon chrome bearing steel, SAE 52100 / BS970 534A99. Maximum operating temperature: 120 °C. Lubricant: Grease or oil. Item Weight: 0.079 kg (0.174 lb) per bearing. Total Width: 24 mm as a matched pair. Limiting speed figures apply to a single bearing; a back-to-back light-preload pair takes a 0.80 factor.
Abutment diameters: d1 min 30 mm, D1 max 42 mm, D2 max 44.5 mm. Chamfer: r min 0.6 mm, r1 min 0.3 mm. Effective Load Centre: 10.8 mm. Internal Free Volume: 3.8 cm³. PCD of lubrication jets: 32.9 mm. Each bearing takes thrust in one direction; the pair locates the shaft in both directions back-to-back or face-to-face.
Cross-references with the same 25 x 47 x 12 mm envelope, 15° angle and light preload: NSK 7005CTRDULP3 and Timken/Fafnir 2MM9105WI. Harmonization Code: 8482.10.5028.
The contact angle is 15° and the preload is light, with an axial preload of 59 N and an axial stiffness of 32 N per micrometre.
Dynamic Load Rating is 11,700 N and Static Load Rating is 7,400 N. Limiting Speed is 47,500 rpm on oil/air and 29,300 rpm on grease.
C is the 15° contact angle, T is the laminated phenolic cage, DU is a universally ground duplex pair, L is light preload and P3 is the precision grade.
