RHP7011CTSULP4Angular Contact Bearing – 55 mm ID, 90 mm OD, 18 mm Width, Open, 15° Contact Angle

Product Description

What this part is: RHP 7011CTSULP4 super-precision angular contact ball bearing, 7000 series, single row, 55 mm bore by 90 mm outside diameter by 18 mm width. Bore: 55 mm. Outside Diameter: 90 mm. Overall Width: 18 mm. Bore Type: Straight. Number of Rows: 1. Rolling Elements: Balls. Bearing Material: Bearing Steel. Closure Type: Open. Design Units: Metric. Series: 7000. Country of Origin: United Kingdom. Decoding the designation: Contact Angle: 15°. Cage Material: Phenolic. Cage Type: Outer ring guided. Precision Class: ABEC 7 / P4, equivalent to the RHP EP7 class marked on the same carton. Preload: Light. Mounting Arrangement: Single universally ground. Internal Clearance: N/A. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. The carton carries this bearing in three schemes at once, all of them 15°: RHP 7011 C T DUL P4, RHP B-series B7011X2 TA DUL EP7, and Fafnir 2MM9111WI CR DUL. Searchable forms of the part number include 7011CTSULP4, 7011-C-T-DUL-P4, 7011 C T SUL P4 and B7011X2TADULEP7. What these specs mean in practice: Dynamic Load Rating: 43.0 kN (9,667 lbf). Static Load Rating: 28.6 kN (6,430 lbf). Permissible Axial Load: 18.9 kN. Limiting Speed, grease: 15,900 rpm. Limiting Speed, oil or oil-air: 24,200 rpm. Effective Load Centre: 18.7 mm. Preload Force: 200 N at light preload, giving 69 N/µm axial rigidity in a back-to-back or face-to-face pair. A 15° contact angle carries more radial load and runs faster than a 25° or 30° angle. Light preload favours speed and low heat generation over axial rigidity. The phenolic outer-ring-guided cage holds a stable rotation at high speed and is rated to 120 °C. Item Weight: 0.380 kg (0.84 lb). Recommended Grease Quantity: 2.2 g per bearing. Quantity and configuration: Unit Quantity: 1 Pc. A single universally ground bearing at light preload, so it mounts back-to-back, face-to-face or in tandem against another bearing of the same designation and preload class. The carton also carries the duplex form of the number, 7011 C T DUL P4, recorded here as an MPN variant. Fitting notes: Shaft Abutment Diameter: 62 mm minimum. Housing Abutment Diameter: 83 mm maximum, with an 85 mm maximum second housing abutment. Bearing Chamfer: 1.1 mm minimum at the bore, 0.6 mm minimum at the front face. Permissible Shaft or Housing Fillet Radius: 1 mm maximum, and 0.6 mm maximum at the front face. Calculation factor f0: 15.5. Interchange guidance: Equivalents on the same envelope and the same 15° contact angle: SKF 7011 CD/P4ADGA, Fafnir 2MM9111WI-DUL, RHP B7011X2TADULEP7. Harmonization Code: 8482.10.50.
