RHP7005CTBSULP6Angular Contact Ball Bearing – Straight Bore, 25 mm ID, 47 mm OD, 12 mm Width, Open, 15° Contact Angle, ABEC 3, Light Preload

Product Description

What this part is

RHP 7005CTBSULP6 angular contact ball bearing, 70 dimension series, 25 mm bore x 47 mm outside diameter x 12 mm width. Bore: 25 mm. Outside Diameter: 47 mm. Overall Width: 12 mm. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Balls. Closure Type: Open. Contact Angle: 15°. Precision Class: ABEC 3 (RHP EP3 / ISO Class 6). Preload: Light. Cage Material: Machined laminated phenolic. Cage Type: Machined, one-piece, inner-ring guided. Design Units: Metric. Material: Chrome bearing steel, high-carbon chromium.

Decoding the designation

7005 gives the 70 dimension series and a 25 mm bore. C: 15° contact angle. TB: machined laminated phenolic cage, one-piece and inner-ring centred. 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. P6: RHP EP3, equal to ISO tolerance class 6 and ABEC 3. Searchable variants: 7005C, 7005-C-TB-SUL-P6, 7005 C TB SUL P6, B7005X2TULEP3, 7005CTBSULP3.

What these specs mean in practice

Dynamic Load Rating: 14.7 kN. Static Load Rating: 7.40 kN. Permissible Axial Load: 5.20 kN. Limiting Speed, oil or oil-air lubrication: 48,700 rpm. Limiting Speed, grease lubrication: 32,000 rpm. Effective Load Centre: 10.8 mm. Item Weight: 0.078 kg (0.17 lb). A 15° contact angle favours speed and radial stiffness over thrust capacity. An inner-ring-centred machined phenolic cage is guided by the rotating ring, which keeps the cage stable where the inner ring turns and the outer stands still. Lubricant: grease or oil. Maximum Operating Temperature: 120 °C.

Quantity and configuration

Unit Quantity: 1 Pc. Arrangement: single bearing, universally ground faces. Two or more universally ground pieces of this designation combine to give light preload in a back-to-back, face-to-face or tandem set. 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: 30 mm minimum. Diameter of Housing Abutment: 42 mm maximum. Chamfer Dimension: 0.6 mm minimum. Measured axial clearance at light preload: -5 µm. Axial rigidity at light preload: 32 N/µm in a back-to-back or face-to-face pair.

Interchange guidance

Same-specification equivalents: FAG B7005-C-T-P6-UL, RHP B7005X2TULEP3. A 7005E or 7005A5 execution shares the 25 x 47 x 12 mm envelope at a 25° contact angle, which is a related size rather than a substitution.
