RHP7208CTDUXP4Angular Contact Ball Bearing – Straight Bore, 40 mm ID, 80 mm OD, 18 mm Width, Open, 15° Contact Angle, P4 Super-Precision, DU Matched Pair.

Product Description

What this part is: RHP 7208CTDUXP4 super-precision angular contact ball bearing, supplied as a universally ground matched pair. Series: 7200, ISO dimension series 02. Bore: 40 mm. Outside Diameter: 80 mm. Overall Width: 18 mm per bearing. Contact Angle: 15°. Precision Class: P4. Precision Rating: ABEC 7. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Chrome bearing steel. Closure Type: Open. Decoding the designation: The carton carries the same bearing in three numbering schemes. RHP 7208 C T DUX P4, RHP B-series 7208X2TADUXEP7, and Fafnir 2MM208WI CR DUX. Contact Angle: 15° — the RHP C, the B-series X2 and the Fafnir 2MM all give the same angle. Cage Material: Phenolic. Cage Type: Machined, outer ring guided. The cage is laminated phenolic resin riding on the outer ring land. Grouping: DU, a paired unit. Precision Class: P4, equivalent to BS292 EP7 and to ABEC 7. What these specs mean in practice: Dynamic Load Rating: 36.5 kN. Static Load Rating: 25.2 kN. Limiting Speed: 30,600 rpm on oil-air lubrication and 18,900 rpm on grease, quoted for a single bearing under spring preload. A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why this execution runs faster than the 25° version of the same envelope. The laminated phenolic cage is light, quiet and self-lubricating, and carries a maximum recommended operating temperature of 120°C. Max Temp: 120°C. Min Temp: -30°C. Quantity and configuration: Unit Quantity: 2 Pcs. Two universally ground bearings supplied as a matched pair. Mounting Arrangement: Universal — universally ground faces allow the pair to be set back-to-back, face-to-face or in tandem. Item Weight: 0.81 lbs per bearing. Interchange guidance: Cross-Reference 1: SKF 7208 CD/P4A. Cross-Reference 2: FAG B7208-C-T-P4S. Cross-Reference 3: NSK 7208CTRP4. Cross-Reference 4: Fafnir 2MM208WICRDUX. Each is a 40 x 80 x 18 mm, 15°, phenolic-caged super-precision execution at the equivalent tolerance class. A 7208 A5 or 7208E carries a 25° contact angle on the same envelope and is a related size rather than a direct substitution. Searchable variants: 7208CTDUXP4, 7208 C T DUX P4, 7208-C-T-DUX-P4, 7208CTRDUP4, 7208X2TADUXEP7, 7208X2TADUXEP7, 2MM208WICRDUX, 2MM208WI CR DUX. Harmonization Code: 8482.10.50.68.
