Product Description

What this part is

NTN NN3926KD1X double row cylindrical roller bearing with tapered bore, type NN, ISO dimension series 39. Bore Diameter: 130 mm. Outside Diameter: 180 mm. Width: 37 mm. Bore Type: Tapered 1:12.

Decoding the designation

NN — double row cylindrical roller bearing, ribs on the inner ring, plain separable outer ring.

39 — ISO dimension series 39, a thinner section than the NN30 series at the same bore.

26 — bore code, 130 mm.

K — 1:12 tapered bore; mounts directly on a tapered spindle journal.

What these specs mean in practice

The NN39 section gives a large bore in a compact radial envelope, suited to hollow spindles and large-bore lathe headstocks. Two rows of rollers give very high radial stiffness.
