RHP7006CTDULP4Super Precision Angular Contact Ball Bearing Pair – 30 mm ID, 55 mm OD, 13 mm Width, Open, 15 Degree, Light Preload, Phenolic Cage

Product Description

What this part is:

RHP 7006CTDULP4 super-precision angular contact ball bearing, supplied as a universally ground matched duplex pair at light preload (Unit Quantity: 2 Pcs). Single row per bearing, open, straight bore, laminated phenolic cage. Bore 30 mm, outside diameter 55 mm, width 13 mm per bearing; total width as a pair 26 mm. ISO series 10 (70xx).

Decoding the designation:

7006 — ISO series 10, bore code 06, giving 30 x 55 x 13 mm.

C — 15° contact angle.

T — laminated phenolic resin cage, outer-ring guided, rated to 120 °C.

DU — duplex universal matched pair, 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.

P4 — ISO Class 4, ABEC 7, RHP class code EP7.

Specifications:

Bore Diameter: 30 mm. Outside Diameter: 55 mm. Width: 13 mm per bearing. Contact Angle: 15°. Cage Material: Laminated phenolic resin. Cage Type: Machined, outer-ring guided. Preload: Light (L), 78 N axial. Axial Stiffness: 39 N per micrometre at light preload. Precision Class: P4 / ISO Class 4 / ABEC 7. Dynamic Load Rating: 15,100 N. Static Load Rating: 10,300 N. Limiting Speed: 42,000 rpm oil/air; 26,000 rpm grease. Running Accuracy: Kia 2.5 µm, Kea 5 µm. Maximum Temperature: 120 °C. Bearing Material: carbon chrome bearing steel (SAE 52100 / BS970 534A99). Lubricant: grease or oil. Item Weight: 0.114 kg per bearing. Country of Origin: United Kingdom.

Dimensions and mounting:

Abutment diameters: d1 min 36 mm, D1 max 49 mm, D2 max 50 mm. Chamfer: r min 1.0 mm, r1 min 0.6 mm. Effective load centre a: 12.2 mm. Internal free volume: 5.3 cm³. PCD of lubrication jets: 39.5 mm. Each bearing takes thrust in one direction; a back-to-back or face-to-face pair locates the shaft in both directions. Limiting speed factor for a back-to-back light-preload pair: 0.80.
