Product Description

What this part is

Decoding the designation

7032 — NSK’s number for the ISO 70-series size, 160 x 240 x 38 mm.

B — 40° contact angle.

DB — duplex back-to-back. Two single-row bearings ground as a matched set and mounted with their outer ring back faces together.

What these specs mean in practice

A 40° contact angle is the highest of the NSK angular contact range and carries the most axial load for a given size, at the lowest speed ceiling. Lubricant: grease or oil.

A back-to-back arrangement sets the two load lines diverging outward, which gives the pair a wide effective support span and high resistance to tilting moments.
