RHPAngular Contact Ball Bearing – 30 mm ID, 62 mm OD, 16 mm Width, Open, 15° Contact Angle, Light Preload, ABEC 3

Product Description

What this part is

RHP 7206CTBSULP6 single-row angular contact ball bearing, ISO dimension series 02. Bore Diameter: 30 mm. Outside Diameter: 62 mm. Overall Width: 16 mm. Contact Angle: 15°. Precision Class: P6 (ABEC 3). Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Preload: Light. Mounting Arrangement: Single universal. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1. Rolling Elements: Balls. Bearing Material: Chrome bearing steel, SAE 52100. Series: 7200. Country of Origin: United Kingdom.

Decoding the designation

7206 gives the ISO series 02 envelope at a 30 mm bore. C is the contact angle code and fixes it at 15°. SUL is the grouping and preload: SU for a single universally ground bearing, L for light preload. P6 is the precision grade, ABEC 3. The carton also carries the Fafnir cross 2M206WI-CR-DUL, and both schemes agree on the 15° angle and the phenolic cage.

What these specs mean in practice

Dynamic Load Rating: 23.0 kN (5,171 lbf). Static Load Rating: 14.7 kN (3,305 lbf). Limiting Speed: 39,200 rpm on oil/air lubrication, 24,200 rpm on grease. Axial Preload: 120 N as a light-preload pair. Axial Stiffness: 43 N/µm as a light-preload pair. Effective Load Centre: 14.2 mm. Item Weight: 0.44 lb (0.194 kg). Lubricant: grease or oil. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. The series 02 section is heavier than a series 10 bearing of the same bore, so it carries more load in the same bore size at a larger outside diameter. A 15° contact angle carries more radial load and runs faster than a 25° or 40° angle, at lower thrust capacity. The laminated phenolic cage is outer-ring guided, light and quiet, and it is what sets the 120 °C ceiling.

Quantity and configuration

Unit Quantity: 1 Pc. SU marks a single universally ground bearing: the inner and outer rings are the same width and the faces are pre-adjusted, so two or more mount back-to-back, face-to-face or in tandem and reach the rated light preload when clamped, with no ground spacer.

Mounting data

Bore Type: Straight. Shaft Abutment Diameter: 36 mm maximum. Housing Abutment Diameters: 56 mm minimum and 57 mm maximum. Bearing Fillet Radius: 1.0 mm minimum on the bore side, 0.6 mm minimum on the outside diameter. Pitch circle diameter for oil/air lubrication jets: 42.4 mm. Internal Volume: 8.8 cm³, which sets the grease charge. Harmonization Code: 8482.10.50.28.
