What Are Main Bearings & Why Are They So Important?

Main bearings (also known as crankshaft bearings or crank bearings) are machined shell bearings that support the crankshaft inside the engine block. Their role is to allow smooth crankshaft rotation while controlling oil film thickness and minimising friction.
Failing main bearings can lead to oil pressure loss, engine knock, bearing seizure, or total engine failure—making them one of the most critical parts of any rebuild.

🔍 Types of Main Bearings Available

We supply a full range of main bearing sets to suit both standard and high-performance applications:

• Bi-metal Bearings: Steel-backed with aluminium alloy lining—ideal for most standard engines.
• Tri-metal Bearings: Feature a steel base, bronze interlayer, and soft overlay for superior load resistance and durability.
• Standard & Undersize Bearings: Available in a variety of sizes for engines with reground crankshafts or specific clearance needs.

⚠️ Signs of Worn or Failing Main Bearings

If you notice any of the following, your main bearings may need replacing:

• Low oil pressure at idle
• Debris or copper flakes in oil
• Main bearing rumble

Replacing main bearings during an engine rebuild is a cost-effective way to prevent deeper internal damage and restore full performance.
