SKFBDAB634201AQFCAngular Contact Thrust Ball Bearing Matched Set of Four – 24 mm ID, 62 mm OD, 16 mm Width, QFC Arrangement

Product Description

What this part is

SKF BDAB634201A/QFC is a matched set of four single-direction angular contact thrust ball bearings, 24 mm bore, 62 mm outside diameter, 16 mm width as listed. BDAB is an SKF drawing-number prefix for single-direction thrust ball bearings of the angular contact type, so this is a thrust bearing rather than a radial angular contact ball bearing.

Decoding the order code

BDAB identifies the product as a single-direction angular contact thrust ball bearing carried under an SKF unique drawing number rather than a catalogue series designation. 634201 is that drawing number and A is the design revision. QFC is the arrangement code for four matched bearings, two arranged face-to-face with the remaining two at either side.

What these specs mean in practice

An angular contact thrust ball bearing takes axial load in one direction with high stiffness and accepts only limited radial load. Four bearings in the QFC arrangement share that axial load between them and take thrust in both directions through the outer pair, giving substantially higher axial capacity and stiffness than a single bearing of the same envelope.

Quantity and configuration

Four bearings, supplied as one matched set. The rings are ground together as a set, so the four stay together as a unit.

Fitting notes

Matched sets are installed in the ground order and orientation, with the two face-to-face bearings centred and the remaining bearing at each side. Clamping is applied evenly across the full ring face.

Interchange guidance

Drawing-number products are made to a specific dimensional and internal design and are identified by the full number. BDAB 634200 and BDAB 634202 are related drawing numbers in the same family. QFCB and QFT are related arrangement codes covering different four-bearing stack orders.
