RHP 7217CTDULP4 super precision angular contact ball bearings, supplied as a matched duplex pair. Series: 7200, ISO dimension series 02. Bore: 85 mm. Outside diameter: 150 mm. Width: 28 mm each bearing, 56 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: 15°. 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 7217CTDULP4, 7217-C-T-DUL-P4, 7217 C T DUL P4, the Fafnir crosses 2MM217WICR-DUL and 217HDL, and the FAG cross B7217C.TPA.P4.UL.
Dynamic Load Rating: 107 kN per bearing. Static Load Rating: 90.5 kN per bearing. Limiting speed for a single bearing: 8,500 rpm with grease, 14,300 rpm with oil/air. As a light-preload back-to-back pair those figures carry a 0.80 factor, giving 6,800 rpm and 11,440 rpm. A 15° contact angle runs faster and carries less thrust than a 25° bearing on the same envelope. Axial preload across the pair: 690 N. Axial stiffness: 120 N/µm. The outer-ring guided phenolic cage runs quietly and takes 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, set at manufacture.
Abutment diameters from the RHP super precision tables: shaft shoulder d1 minimum 95 mm, housing shoulder D1 maximum 140 mm, D2 maximum 144 mm. Fillet radius r minimum 2.5 mm, r1 minimum 1.0 mm. Effective load centre a = 29.7 mm. Internal free volume 78.5 cm³ per bearing. Lubrication jet pitch circle 109.8 mm. Mass 1.782 kg per bearing, 3.564 kg for the pair.
Same-specification equivalents at 15° and light preload: SKF 7217 CD/P4ADGA, Fafnir 2MM217WICR-DUL, FAG B7217C.TPA.P4.UL, NSK 7217CTRDULP4. NSK 7217CTYNDULP4 is the same size and preload on a polyamide cage. RHP 7217A5TDULP4 is a related size at 25°.
