Product Description

What this part is

RHP 7006ETSUMP4 super-precision angular contact ball bearing. Series: 7006. Bore: 30 mm. Outside Diameter: 55 mm. Overall Width: 13 mm. Contact Angle: 25°. Precision Class: P4 (ABEC 7). Cage Material: Phenolic. Cage Type: Machined. Preload: Medium. Number Of Rows: 1. Rolling Elements: Balls. Closure Type: Open. Bore Type: Straight. Bearing Material: Bearing steel. Country of Origin: United Kingdom.

Decoding the designation

7006 is the ISO 70 dimension series at a 30 mm bore. E gives Contact Angle: 25°, which carries more thrust load than a 15° execution on the same envelope and runs to a lower speed limit. T is the machined phenolic cage, light and self-lubricating, rated for continuous service to 120 °C. SU is universal grinding: two bearings of this designation mount back-to-back, face-to-face or in tandem with no shims and no measured spacers. M sets Preload: Medium. P4 is the ABEC 7 tolerance grade.

What these specs mean in practice

Dynamic Load Rating: 15.6 kN. Static Load Rating: 10.2 kN. Limiting Speed: 28,000 rpm. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. Item Weight: 0.26 lb. Internal Clearance: N/A — the bearing is preloaded, so it is set by preload rather than by running clearance. Medium preload gives higher axial and radial rigidity than light preload, which holds shaft position under cutting load, and it generates more heat at speed. The 25° angle suits spindles and screw drives where the thrust component is high relative to the radial load.

Quantity and configuration

Unit Quantity: 1 Pc. Mounting Arrangement: universally matchable single. One piece ships, ground so that it pairs with any other bearing of the same designation. Carton and cross designations, all recorded as search terms: 7006ETSUMP4, 7006 E T SUM P4, 7006-E-T-SUM-P4, 7006ETDUMP4, B7006X3TAUMEP4, 3MM9106WI-CR-SUM.

Fitting notes

Faces are flush-ground for stacking, so preload is established by the grinding rather than by shim thickness. Abutment faces on shaft and housing bear on the ring faces, and the phenolic cage sets the 120 °C ceiling on continuous running temperature.

Interchange guidance

Direct 25° P4 equivalents: SKF 7006 ACE/P4A, Fafnir 3MM9106WI, NSK 7006A5. A 7006C, 7006 X2 or 2MM9106WI is a related size at a 15° contact angle on the same 30 x 55 x 13 mm envelope, and it is a different part.
