Product Description

What this part is

NDH Q0L07DTX7A super-precision angular contact ball bearing, supplied as a two-piece duplex tandem set. Bore Diameter: 35 mm. Outside Diameter: 62 mm. Width: 14 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Preload: Medium. Mounting Arrangement: Tandem (DT). Unit Quantity: 2 Pcs.

Decoding the designation

Q — NDH phenolic separator (cage).

0L07 — NDH’s number for the ISO 7007 size, 35 x 62 x 14 mm, the extra-light 70-series section.

DT — duplex tandem. Two single-row bearings ground as a matched set, mounted facing the same direction. Not a double-row bearing.

X — medium preload.

7 — NDH tolerance grade, equivalent to ABEC 7 / ISO P4.

What these specs mean in practice

The 70-series section is thinner than the 72-series, giving higher speed capability in a compact housing bore. A 15° contact angle favours speed and radial stiffness. The tandem arrangement shares axial load in one direction across both bearings, and the medium preload raises stiffness. Rolling Elements: Ball. Closure Type: Open. Bore Type: Straight.

Quantity and configuration

Two bearings forming one factory-matched DT set.
