SNR7205.C.G1.DU.J84Super-Precision Angular Contact Ball Bearing, 25 x 52 x 15 mm, 15° Contact Angle, ABEC 7 / P4, Medium Preload

Product Description

What this part is:

SNR Machline 7205CG1DUJ84 super-precision angular contact ball bearings, supplied as a universal duplex pair. Bore: 25 mm. Outside Diameter: 52 mm. Width: 15 mm per bearing. Contact Angle: 15°. Unit Quantity: 2 Pcs.

Decoding the designation:

7205 — ISO 72-dimension series angular contact envelope, 25 x 52 x 15 mm.

C — 15° contact angle in SNR’s scheme.

G1 — SNR’s high-load-capacity version code, developed for the 72 series.

DU — a pair of universal bearings. Universal grinding leaves the ring faces flush once preloaded, so the pair can be mounted in any arrangement; DU also selects bore and outside diameter to within half the ISO tolerance.

J84 — the 8 is the medium preload grade; the 4 is precision class ISO 4 / P4 / ABEC 7.
