RHP7005-E-T-DUM-P4Super Precision Angular Contact Ball Bearing – 25 mm ID, 47 mm OD, 12 mm Width, Open, 25° Contact Angle, Medium Preload

Product Description

What this part is:

RHP 7005-E-T-DUM-P4 super precision single-row angular contact ball bearing, 25 x 47 x 12 mm, 25° contact angle, medium preload, ISO Class 4 (P4). Unit Quantity: 1 Pc, one piece from a factory duplex medium-preload pair.

Decoding the designation:

7005 — ISO 7000 series size, 25 x 47 x 12 mm.

E — 25° contact angle.

T — laminated phenolic resin cage, machined and outer-ring guided.

DU — duplex universal. Rings are ground to the same width so the bearing pairs back-to-back, face-to-face or in tandem.

M — medium preload.

P4 — RHP P4, ISO Class 4, ABEC 7, BS292 EP7.

The carton carries the same bearing in three schemes: RHP 7005-E-T-DUM-P4, RHP B-series B7005 X3 TADUM EP7, and Fafnir 3MM9105WI-DUM.
