RHP 7030ETSULP4 super precision angular contact ball bearing. Bore: 150 mm. Outside diameter: 225 mm. Width: 35 mm. Series: 70, ISO dimension series 10. Single row, open, straight bore, universally faced. Manufactured in the United Kingdom.
Contact Angle: 25°. Cage: machined laminated phenolic resin, outer ring guided. Grouping: SU, single universal. Preload: Light. Precision Grade: P4, equivalent to EP7, ABEC 7 and ISO Class 4.
Dynamic Load Rating: 143 kN. Static Load Rating: 160 kN. Limiting speed: 7,900 rpm on oil/air lubrication and 5,100 rpm on grease. A 25° contact angle carries more thrust and less speed than a 15°. P4 holds tighter running accuracy, which lowers runout and vibration in a spindle: inner ring radial runout 6 µm maximum, outer ring radial runout 10 µm maximum.
Axial preload for a light-preload pair of this size and angle: 1,850 N. Axial stiffness at light preload: 446 N/µm. Light preload suits applications where loads and speeds are moderate. Preloaded bearings are set at manufacture, so no internal clearance value applies.
One bearing. Universal face control means the inner and outer rings are the same width and the face steps are pre-adjusted, so two bearings of this designation mount back-to-back, face-to-face or in tandem at the marked preload without ground spacers.
Inner ring abutment diameter d1: 162 mm minimum. Outer ring abutment diameters D1 and D2: 213 mm and 218 mm maximum. Fillet radii r and r1: 2.5 mm and 1.5 mm minimum. Effective load centre a: 61.2 mm. Lubrication jet pitch circle diameter: 178.1 mm. Internal free volume: 171.2 cm3. Maximum recommended operating temperature: 120 °C. Rings and balls: SAE 52100 through-hardened chrome bearing steel. Mass: 4.164 kg (9.18 lb).
Carton designations: 7030ETSULP4, 7030-E-T-SUL-P4, B-7030-X3-T-UL-EP7, 3MM9130WICRSUL. Fafnir 3MM9130WI is the 25° equivalent envelope. NSK 7030A5TRSULP4 is the current-scheme equivalent at 25° with the same outer-ring-guided phenolic cage. SKF 7030 ACD/P4ADGA is a 25° light-preload equivalent.
