7205 — ISO 72-series angular contact envelope, 25 x 52 x 15 mm.
A — 30° contact angle. The older RHP angle code X4 also reads 30°, which is why the carton number 7205X4TADUMEP5 appears on these parts.
T — machined laminated phenolic cage. The carton code TA denotes the one-piece outer-ring-centred version.
DUM — duplex universal, medium preload. Ground faces let the pair be assembled back-to-back, face-to-face or tandem.
P5 — ISO tolerance class 5, equivalent to ABEC 5.
Bore Diameter: 25 mm.
Outside Diameter: 52 mm.
Width: 15 mm.
Contact Angle: 30°.
Cage Material: Laminated phenolic.
Precision Class: P5 (ISO class 5 / ABEC 5).
Preload: Medium.
Unit Quantity: 2 Pcs.
Envelope: 25 x 52 x 15 mm. Number Of Rows: single row per bearing. Bore Type: Straight. DUM pairs are ground and marked as a set for back-to-back, face-to-face or tandem mounting.
Carton designation: 7205X4TADUMEP5. Other forms of the number: 7205-A-T-DUM-P5 and 7205 A T DUM P5. The Fafnir 3MM205WI marking is 25° and is a separate angle from this 30° bearing.
30°. The letter A in the designation and the X4 code on the carton number 7205X4TADUMEP5 both indicate 30°.
DUM is duplex universal with medium preload. The ground faces allow back-to-back, face-to-face or tandem mounting.
