RHP 7015ETDULP4 super precision angular contact ball bearings, supplied as a matched duplex pair. Series: 7000, ISO dimension series 10. Bore: 75 mm. Outside diameter: 115 mm. Width: 20 mm each bearing, 40 mm assembled. Straight bore, open on both faces, ball rolling elements in chrome bearing steel to SAE 52100. Country of origin as recorded: United Kingdom.
Contact Angle: 25°. Cage: laminated phenolic resin, machined and outer-ring guided. Grouping: DU, paired unit. Preload: L, light. Precision Grade: P4, equal to RHP EP7 and ABEC 7. Searchable forms include 7015ETDULP4, 7015-E-T-DUL-P4, 7015 E T DUL P4, the RHP B-series form B7015X3TADULEP7 and the Fafnir cross 3MM9115WICR-DUL.
Dynamic Load Rating: 45.5 kN per bearing. Static Load Rating: 43.5 kN per bearing. Limiting speed for a single bearing: 10,000 rpm with grease, 15,100 rpm with oil/air. As a light-preload back-to-back pair those figures carry a 0.80 factor, giving 8,000 rpm and 12,080 rpm. A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Axial preload across the pair: 490 N. Axial stiffness: 229 N/µm. The outer-ring guided phenolic cage runs to 120 °C continuously.
Two bearings, a matched duplex pair. Universal face control means they mount back-to-back, face-to-face or in tandem at the same light preload, which is set at manufacture. The high point of radial runout is marked with a burnished spot on the inner ring face and a V line on the outer diameter.
Abutment diameters from the RHP super precision tables: shaft shoulder d1 minimum 82 mm, housing shoulder D1 maximum 108 mm, D2 maximum 110 mm. Fillet radius r minimum 1.1 mm, r1 minimum 0.6 mm. Effective load centre a = 32.1 mm. Internal free volume 27.8 cm³ per bearing. Lubrication jet pitch circle 89.4 mm. Mass 0.639 kg per bearing, 1.278 kg for the pair.
Same-specification equivalents at 25° and light preload: Fafnir 3MM9115WICR-DUL, FAG B7015-E-T-P4S-UL, NSK 7015A5TRDULP4, SKF 7015 ACD/P4A with light preload. RHP 7015CTDULP4 is a related size at 15°.
