RHP 7009ETDUMP4 super precision angular contact ball bearing, ISO dimension series 10, supplied as a matched duplex pair. Bore: 45 mm. Outside Diameter: 75 mm. Width: 16 mm. Contact Angle: 25°. Number of Rows: 1 per bearing. Rolling Elements: Steel balls. Bearing Material: High carbon chrome bearing steel to SAE 52100. Bore Type: Straight. Closure Type: Open.
Series: 7000, ISO dimension series 10. Base Number: 7009. Contact Angle: 25°, the RHP E execution, catalogued as A5. Cage Material: Laminated phenolic resin. Cage Type: Machined, outer-ring guided. Grouping: DU, a paired unit. Preload: Medium. Precision Grade: P4, equivalent to ABEC 7 and ISO Class 4. Searchable forms of the number include 7009ETDUMP4, 7009-E-T-DUM-P4, 7009 E T DUM P4, B7009X3TADUMEP7 and 3MM9109WICRDUM.
Dynamic Load Rating: 23.1 kN. Static Load Rating: 18.3 kN. Limiting Speed, oil or oil-air lubrication: 26,800 rpm. Limiting Speed, grease lubrication: 16,500 rpm. Both figures are single-bearing values; a back-to-back pair at medium preload runs at 0.60 of the tabulated speed.
A 25° contact angle carries more thrust and less speed than the 15° C execution on the same envelope, which makes it the choice where axial load dominates. Axial Preload: 490 N paired. Axial Stiffness: 181 N per micrometre paired. Effective Load Centre: 22.0 mm. Maximum Operating Temperature: 120 °C, set by the laminated phenolic cage. Lubricant: grease or oil.
Inner Ring Abutment Diameter: 51 mm minimum. Outer Ring Abutment Diameter: 69 mm maximum. Housing Abutment Diameter: 70 mm maximum. Fillet Radius r min: 1.0 mm. Fillet Radius r1 min: 0.6 mm. Internal Volume: 11.2 cm3. Mass: 0.238 kg per bearing.
Unit Quantity: 2 Pcs. Universal face control means the pair mounts back-to-back or face-to-face at the same preload, and shares load equally when mounted in tandem.
The RHP B-series form is B7009X3TADUMEP7 and the Fafnir cross is 3MM9109WICRDUM. FAG B7009-E-T-P4S-DUM is the FAG 25° medium-preload pair. SKF 7009 ACD/P4A is the SKF form of the size; specify the matching preload class. A 7009C shares the 45 x 75 x 16 mm envelope at a 15° contact angle, making it a related size.
