MRC 1907RDB#3 angular contact ball bearing set. Bore Diameter: 35 mm. Outside Diameter: 55 mm. Width: 10 mm per bearing. Total Width: 20 mm for the pair. Series: 1900 extremely light. Contact Angle: 15°. Closure Type: Open. Rolling Elements: Ball. Material: Chrome Steel. Lubricant: Oil.
1907 — MRC base number. The 1900 series is the extremely light section; bore code 07 gives a 35 mm bore.
R — 15° contact angle with a counterbored outer ring.
DB — back-to-back duplex pair, ground as a matched set for preload.
#3 — Precision Class 3: tighter running and dimensional tolerance and lower running vibration than a standard-class bearing.
Mounting Arrangement: back-to-back. Bore Type: Straight. Number Of Rows: 2. Unit Quantity: 2 pieces, a factory duplex pair. Harmonization Code: 8482.10.50.28.
35 x 55 x 10 mm per bearing, 20 mm stacked. A 15° contact angle favors speed over thrust capacity compared with 40°, and the back-to-back pair takes thrust in both directions with high moment stiffness.
The MRC 19nn series maps to ISO 719nn, so 1907R corresponds to ISO 71907 at 35 x 55 x 10 mm. Interchanges at 15° in a back-to-back pair: SKF 71907 CD/DB and FAG 71907-C-DB.
35 mm bore, 55 mm outside diameter, 10 mm width per bearing.
DB is a back-to-back duplex pair, two bearings ground as a matched set for preload.
15°, set by the R type letter.
