RHP7009CTSULP4Super Precision Angular Contact Ball Bearing – 45 mm ID, 75 mm OD, 16 mm Width, Open, 15° Contact Angle, Light Preload, ABEC 7.

Product Description

What this part is: RHP 7009CTSULP4 super precision angular contact ball bearing, ISO dimension series 10. Bore: 45 mm. Outside Diameter: 75 mm. Width: 16 mm. Contact Angle: 15°. Number of Rows: 1. Rolling Elements: Steel balls. Bearing Material: Carbon chrome bearing steel to SAE 52100. Bore Type: Straight. Closure Type: Open. Decoding the designation: Series: 7000, ISO dimension series 10. Base Number: 7009. Contact Angle: 15°. Cage Material: Laminated phenolic resin. Cage Type: Machined, outer-ring guided. Grouping: SU, single universal. Preload: Light. Precision Grade: P4, equivalent to ABEC 7 and ISO Class 4. Searchable forms of the number include 7009CTSULP4, 7009-C-T-SUL-P4, 7009 C T SUL P4, 7009X2TADUEP7 and 2MM9109WICRDUL. Load ratings and speed: Dynamic Load Rating: 24.4 kN. Static Load Rating: 19.3 kN. Limiting Speed, oil or oil-air lubrication: 30,500 rpm. Limiting Speed, grease lubrication: 18,800 rpm. Both figures are single-bearing values; a back-to-back pair at light preload runs at 0.80 of the tabulated speed. What these specs mean in practice: A 15° contact angle favours rotational speed and radial stiffness, while a 25° execution on the same envelope trades speed for thrust capacity. Light preload is the most widely used level, suiting loads and speeds that are not extreme. Axial Preload: 150 N paired. Axial Stiffness: 58 N per micrometre paired. Effective Load Centre: 16.0 mm. Maximum Operating Temperature: 120 °C, set by the laminated phenolic cage. Lubricant: grease or oil. Mounting data: 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. Quantity and configuration: Unit Quantity: 1 Pc. Universal face control means this bearing pairs with another of the same execution back-to-back or face-to-face at the rated preload, and shares load equally in tandem. Interchange guidance: Cross-Reference: SKF 7009 CDGA/P4A. The RHP B-series form is 7009X2TADUEP7 and the Fafnir cross is 2MM9109WICRDUL. A 7009A5 shares the 45 x 75 x 16 mm envelope at a 25° contact angle, making it a related size rather than a direct substitution.
