Key Features & Benefits – ACL Race Suzuki M16A main bearing set 0.025 mm
The ACL Race Suzuki M16A main bearing set 0.025 mm is a main bearing set (main bearing shells) for the Suzuki M16A engine. The 0.025 mm size uses a thicker shell than standard, giving 0.001" less oil clearance.
Race Series H design features include tri-metal construction, 3/4-grooved mains, increased eccentricity, and enlarged I.D. chamfers. These details support repeatable clearances, oil film formation, and crankshaft fillet-radius accommodation during rebuild work.
When is this useful?
This 0.025 mm variant fits builds where measured journal size and your clearance target call for a tighter oil clearance than a standard set would deliver. Selecting the correct main bearing set directly affects crank stability and lubrication longevity.

Selection & installation tips
- Measure journals: measure crank main journals in multiple positions and choose Standard, 0.025mm, 0.25mm, or X-version to match your build plan.
- Read 0.025 mm correctly: the 0.025 mm option is a thicker shell intended for tighter oil clearance, not extra clearance.
- Know X-version: X-version/HX adds 0.025 mm (0.001") extra oil clearance on a standard-size shaft versus an H-STD set.
- Oil path alignment: ensure oil holes and grooves align correctly and nothing blocks the oil feed during assembly.
- Verify clearance: check oil clearance at each main position during assembly and keep bearing halves paired within the set.
Before assembly, match your measured journal sizes, housing condition, and clearance target to the 0.025 mm variant, then confirm markings and clearances during installation so the fit follows your engine’s actual dimensions.
