Nachi 6001-012 Distributor Bearing – 12.5×28×8 mm (Japan)

The Nachi 6001-012 distributor bearing is a precise Japanese-made component used in many classic Honda models equipped with a mechanical ignition distributor. With its specific dimensions of 12.5 × 28 × 8 mm, this bearing ensures smooth rotation of the distributor shaft, stable ignition timing and long-lasting reliability.

Nachi bearings were widely used by Honda as factory-installed (OE-type) components throughout the 1980s, 1990s and early 2000s. Because this exact size was never sold by Honda as a standalone OEM part, the correct selection is always made by comparing the bearing removed from the distributor. Nachi 6001-012 is the closest match to the original factory specification.

FAQ – Nachi 6001-012 Distributor Bearing

Was Nachi 6001-012 used as a factory bearing in Honda distributors?
Yes. Nachi bearings were commonly used as OE-type bearings in many Honda distributors throughout the 80s and 90s.

How do I confirm the correct fitment?
Measure the old bearing: inner diameter 12.5 mm, outer diameter 28 mm, width 8 mm. This specific size fits only certain Honda distributors, so verifying dimensions is essential.

How does the Nachi bearing compare to the PFI replacement?
Nachi provides the closest match to the original factory specification and is generally more durable. The PFI 6001-012 is a good-quality substitute, but the Nachi version remains the preferred choice for OEM-level performance and longevity.
