NSK7912CTSULP4Angular Contact Ball Bearing – 60 mm ID, 85 mm OD, 13 mm Width, 15° Contact Angle, Light Preload, ABEC 7

Product Description

What this part is:

NSK 7912CTSULP4 is a single-row angular contact ball bearing, 79 extra-light series, 60 x 85 x 13 mm, with a 15° contact angle, light preload and ISO Class 4 (ABEC 7) precision. It is single universally ground (SU) for matched-set stacking.

Decoding the designation:

7912 — the ISO 71912 extra-light 19-series size, 60 x 85 x 13 mm.

C — a 15° contact angle, which favours speed and radial capacity over thrust capacity.

SU — single universally ground, so the bearing stacks with others of the same designation into a matched set in any orientation.

L — light preload, 113 N when paired.

P4 — ISO Class 4 running accuracy, equivalent to ABEC 7.
