Product Description

What this part is

RHP 7205CTDULP4 super-precision angular contact ball bearing duplex pair. Series: 7200. Bore: 25 mm. Outside Diameter: 52 mm. Overall Width: 15 mm each. Total Width: 30 mm across the pair. Contact Angle: 15°. Precision Class: P4 (ABEC 7). Cage Material: Phenolic. Cage Type: Machined. Preload: Light. Rolling Elements: Balls. Number Of Rows: 2. Closure Type: Open. Bore Type: Straight. Bearing Material: Bearing steel. Design Units: Metric. Country of Origin: United Kingdom. Condition: new old stock, original carton.

Decoding the designation

7205 is the ISO 72 dimension series at a 25 mm bore. C gives Contact Angle: 15°, which favours speed and radial rigidity over thrust capacity. T is the machined phenolic cage, light and self-lubricating, rated for continuous service to 120 °C. DU is a duplex pair, ground as a matched set so the two bearings stack directly with no shims. L sets Preload: Light. P4 is the ABEC 7 tolerance grade. The RHP B-series form of the same bearing is 7205X2TADULEP7, where X2 is the 15° code and EP7 the equivalent precision grade.

What these specs mean in practice

Dynamic Load Rating: 15.6 kN / 3,507 lbf. Static Load Rating: 10.4 kN / 2,338 lbf. Limiting Speed: 20,000 rpm. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. Item Weight: 0.56 lb. Harmonization Code: 8482.10.50.28. Internal Clearance: N/A, since the pair is set by preload rather than by running clearance. Light preload holds friction torque and heat generation low, which is what supports the 20,000 rpm figure on a 25 mm bore. Lubricant: grease or oil.

Quantity and configuration

Unit Quantity: 2 Pcs. One purchase delivers a matched duplex pair. Total Width: 30 mm assembled. Mounting Arrangement: universally matchable, so the pair runs back-to-back, face-to-face or in tandem. Carton and cross designations, all recorded as search terms: 7205CTDULP4, 7205 C T DUL P4, 7205-C-T-DUL-P4, 7205X2TADULEP7, 7205X2TADUEP7, 2MM205WI-CR-DUL.

Fitting notes

Ring faces are flush-ground for stacking, so the light preload is established by the grinding rather than by shim thickness. The housing bore length must accept the 30 mm assembled width. The phenolic cage sets the 120 °C ceiling on continuous running temperature.
