RHP7021ETSULP4Super Precision Angular Contact Ball Bearing – Straight Bore, 105 mm ID, 160 mm OD, 26 mm Width, Open, 25° Contact Angle, Single Universal Light Preload, ABEC 7

Product Description

What this part is:

RHP 7021ETSULP4 super precision single-row angular contact ball bearing, single universally ground, 105 x 160 x 26 mm, 25° contact angle, light preload, open. Unit Quantity: 1 Pc.

Decoding the designation:

7 — single-row angular contact ball bearing.

0 — ISO dimension series 10.

21 — bore code, multiplied by five to give a 105 mm bore.

E — 25° contact angle (legacy RHP code, equal to the current A5).

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

SU — single universally ground: face control that lets it pair with another SU bearing back-to-back, face-to-face or in tandem.

L — light preload.

P4 — ISO Class 4 precision, equal to RHP P4, BS292 EP7 and ABEC 7.
