Product Description

What this part is

RHP 7026CTDULP4 super precision angular contact ball bearing set. Series: 70, ISO dimension series 10. Bore: 130 mm. Outside Diameter: 200 mm. Width: 33 mm per bearing. Country of origin: United Kingdom. Searchable forms: 7026CTDULP4, 7026-C-T-DUL-P4, 7026 C T DUL P4, 7026C, and the carton cross-references B7026X2TADUEP7 and 2MM9126WI-CR-DUL.

Decoding the designation

Contact Angle: 15°. Cage: laminated phenolic resin, outer ring guided. Grouping: DU, a universally ground pair. Preload: Light, 980 N axial. Precision Grade: P4 — ABEC 7, RHP EP7, ISO Class 4. The carton also carries the RHP B-series form B7026X2TADUEP7, in which X2 is the 15° angle and EP7 is the same P4 class.

What these specs mean in practice

Dynamic Load Rating: 129,000 N per bearing. Static Load Rating: 137,000 N per bearing. Limiting speed for a single bearing: 10,200 rpm on oil/air, 6,500 rpm on grease. A 15° contact angle carries more speed and less thrust than a 25°. Light preload gives the pair an axial stiffness of 167 N/µm. The laminated phenolic cage runs quietly at speed and is rated to 120 °C.

Quantity and configuration

Two pieces, supplied as a universally faced pair. Universal face control lets the pair mount back-to-back, face-to-face or in tandem at the same preload value. Total width mounted side by side: 66 mm.

Fitting notes

Effective load centre: 38.6 mm. Abutment dimensions: shaft shoulder 140 mm maximum, housing shoulder 190 mm minimum, outer ring abutment 194 mm maximum. Corner radii: 2.5 mm minimum outer, 1.0 mm minimum inner. Recommended shaft fit at P4 for a 130 mm seat is a mean 3.5 µm interference; a locating housing bore takes a mean 7 µm clearance. Internal free volume is 131.8 cm³ per bearing, which sets the grease charge at 20 to 30 per cent fill. Mounted back-to-back at light preload the recommended limiting speed is 80 per cent of the single-bearing figure.

Interchange guidance

Same-spec equivalents: SKF 7026 CD/P4ADGA, FAG B7026-C-T-P4S-DUL, Fafnir 2MM9126WI-CR-DUL, Barden 126HDL. Related size: 7026A5TRDUL, the 25° version of the same envelope.
