Product Description

What this part is

RHP 7006CTSULP0 angular contact ball bearing, 70 dimension series, 30 mm bore x 55 mm outside diameter x 13 mm width. Bore: 30 mm. Outside Diameter: 55 mm. Overall Width: 13 mm. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Balls. Closure Type: Open. Contact Angle: 15°. Precision Class: ABEC 1 (RHP EP1 / ISO Normal). Preload: Light. Cage Material: Machined laminated phenolic. Cage Type: Machined, outer-ring guided. Design Units: Metric. Material: Chrome steel SAE 52100. Country of Origin: United Kingdom.

Decoding the designation

7006 gives the 70 dimension series and a 30 mm bore. C: 15° contact angle. T: machined laminated phenolic cage, outer-ring guided. SU: single bearing with universally ground faces, so any two or more pieces of the same designation assemble back-to-back, face-to-face or in tandem. L: light preload. P0: RHP EP1, equal to ISO normal tolerance and ABEC 1. The carton also carries Fafnir 2MM9106WI-CR-SUL and RHP B-series B7006X2-TUL-EP1; the Fafnir 2MM prefix and the RHP X2 code both give the same 15° angle. Searchable variants: 7006C, 7006-C-T-SUL-P0, 7006 C T SUL P0.

What these specs mean in practice

Dynamic Load Rating: 19.1 kN (4,294 lbf). Static Load Rating: 10.3 kN (2,316 lbf). Permissible Axial Load: 6.85 kN. Limiting Speed, oil or oil-air lubrication: 41,200 rpm. Limiting Speed, grease lubrication: 27,100 rpm. Effective Load Centre: 12.2 mm. Item Weight: 0.114 kg (0.25 lb) per bearing. A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why this angle dominates high-speed spindle work. The machined laminated phenolic cage is light and outer-ring guided, giving stable cage rotation at speed. Lubricant: grease or oil. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C.

Quantity and configuration

Unit Quantity: 2 Pcs. Two bearings of the same designation with universally ground faces, which assemble back-to-back, face-to-face or in tandem and give light preload when clamped. Internal Clearance: N/A — face grinding sets the axial position on a universally ground preloaded execution, in place of a radial clearance class.

Fitting notes

Diameter of Shaft Abutment: 36 mm minimum. Diameter of Housing Abutment: 49 mm maximum. Chamfer Dimension: 1 mm minimum. Measured axial clearance at light preload: -3 µm.

Interchange guidance

Same-specification equivalents: NSK 7006CTRSULP4 in the super-precision class, Fafnir 2MM9106WI-CR-SUL, RHP B7006X2-TUL-EP1. A 7006E or 7006A5 execution shares the 30 x 55 x 13 mm envelope at a 25° contact angle, which is a related size rather than a substitution.
