SKFBDAB634202CDGBAngular Contact Ball Bearing, Special-Order BDAB Designation, Matched Set (DGB) — Built-to-Drawing Part

Product Description

What this part is

SKF BDAB 634202 C/DGB angular contact ball bearing. Series: BDAB, SKF’s built-to-drawing angular contact range, produced to an equipment builder’s specification rather than to a catalogue envelope. Rolling Elements: balls. Bearing Material: bearing steel. Closure: open. Arrangement: DGB matched duplex set. Unit Quantity: 2 pieces, one matched set. Country of manufacture: Italy.

Decoding the designation

BDAB is SKF’s built-to-drawing angular contact ball bearing series. 634202 is the drawing reference. C is the execution letter within that drawing series.

DGB — matched duplex set, light preload.

What these specs mean in practice

A built-to-drawing bearing is made to one application’s requirement, so its contact angle, ball complement and preload are chosen for that machine rather than for a catalogue range. Light preload gives a stiffer shaft location than an extra light set while keeping heat generation modest. A duplex matched pair is ground as a unit so the two bearings share the preload equally when clamped.

Quantity and configuration

Two pieces, one DGB matched duplex set, supplied together and mounted together.

Interchange guidance

Special-order designations are unambiguous because each is unique to one application: a machine parts list calling out BDAB634202C/DGB or BDAB 634202 C/DGB names this part. Also written BDAB-634202-C-DGB, BDAB634202CDGB, BDAB634202 and 634202. A catalogue 7000-series bearing on the same envelope is a related size rather than an interchange, because a built-to-drawing bearing differs from the nearest catalogue part in contact angle, ball complement or preload. Harmonization Code: 8482.10.50.
