Product Description

What this part is

NDH Q20213DTL7A super-precision angular contact ball bearing, supplied as a matched tandem pair. Bore Diameter: 65 mm. Outside Diameter: 120 mm. Overall Width: 23 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Preload: Light. Mounting Arrangement: Tandem (DT).

Decoding the designation

Q — phenolic separator.

20213 — NDH’s number for the ISO 7213 size, 65 x 120 x 23 mm. The 20-series prefix is the 15° angular contact family.

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

L — light preload.

7 — NDH tolerance grade, equivalent to ABEC 7.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness. The tandem arrangement shares thrust in one direction across both bearings. ABEC 7 tolerances suit machine tool spindles and other high-accuracy shafts.

Quantity and configuration

Unit Quantity: 2 Pcs, one matched DT pair. Carton markings: Q20213 DT L7A, 7213 C T P4, 2MM213WI CR.
