The front wheel hub contains the Wheel bearings. The brake rotor bolts to the hub on disc brake models.

Overview

drum hub vs. disk hub - The drum hub is shorter, so that after the drum is placed over it, the track exactly matches the disc version.

Specs

The hub slips over the spindle, thus the bearing sizes must match

These use the large bearings, and fit on the small spindles (early 1200 drum struts or disc struts). They have 10mm less track than the disc hubs (5mm per side).

H10 Hubs

B110 disc hub * Large Bearings * for small spindle

Nissan 40202-H1005 hub fits: * Datsun B110 disc brake strut * Datsun 120Y disc brake strut to 7510

Will bolt to the early drum brake spindles & struts, but will increase track ~10 mm.

A08 Hubs

1976-up Datsun 1200 hub

A08 hubs use 510-style bearings -- #210 (outer) and #A08 (inner). They are smaller O.D. than B110 bearings, but fit on larger spindles.

27mm inner bearing journal diameter 0.6875" outer bearing journal diameter

Hubs using A08 bearings include:
