RHP 7222ETDULP4 super precision angular contact ball bearing, half of a light-preload duplex pair. Series: 72, ISO dimension series 02. Bore: 110 mm. Outside Diameter: 200 mm. Width: 38 mm. Country of origin: United Kingdom. Searchable forms: 7222ETDULP4-1/2PR, 7222-E-T-DUL-P4, 7222E, 7222ACD, and the carton cross-references B7222X3TAULEP7 and 3MM222WI.
Contact Angle: 25°. Cage: laminated phenolic resin, outer ring guided. Grouping: DU, universally ground for pairing. Preload: Light, 1,960 N axial when paired. Precision Grade: P4 — ABEC 7, RHP EP7, ISO Class 4. The suffix -1/2PR marks one bearing out of a pair.
Dynamic Load Rating: 168,000 N. Static Load Rating: 153,000 N. Limiting speed: 9,500 rpm on oil/air, 6,200 rpm on grease. The 72 section is the heaviest of the three super precision series, so a 7222 carries markedly higher load than a 7022 on the same 110 mm bore. A 25° contact angle carries more thrust and less speed than a 15°. Light preload gives a paired axial stiffness of 368 N/µm. The laminated phenolic cage runs quietly at speed and is rated to 120 °C.
One bearing, universally faced. It pairs with any other 7222 of the same angle and preload class at the light preload value, in back-to-back, face-to-face or tandem order.
Effective load centre: 55.1 mm. Abutment dimensions: shaft shoulder 122 mm maximum, housing shoulder 188 mm minimum, outer ring abutment 193 mm maximum. Corner radii: 2.5 mm minimum outer, 1.5 mm minimum inner. Recommended shaft fit at P4 for a 110 mm seat is a mean 3 µm interference; a locating housing bore takes a mean 7 µm clearance. Internal free volume is 192.5 cm³, which sets the grease charge at 20 to 30 per cent fill. The high point of radial runout is marked by a burnished spot on the inner ring face and a V line on the outer ring diameter.
Same-spec equivalents: SKF 7222 ACDGA/P4A, FAG B7222-E-T-P4S-UL, Fafnir 3MM222WI. Related size: 7222CTRSUL, the 15° version of the same envelope, and 7022A5TRDUL, the lighter 70 section on the same bore.
