Premium TK486V Engine Crankshaft & Rod Bearing Set

High-strength bimetal construction with precision-aligned oil grooves for optimal lubrication under extreme loads. Features advanced polymer-coated backings to prevent fretting corrosion and minimize heat distortion.

CNC-machined to exact OEM tolerances (±0.001") for seamless compatibility with TK486V diesel engines. Includes both main and connecting rod bearings in one complete kit.

Ideal for industrial equipment rebuilds, marine propulsion systems, and heavy-duty generator maintenance. Triple-layer lead-free alloy delivers 30% longer service life than standard bearings.

Direct replacement part with laser-etched positioning marks for foolproof installation. Vacuum-sealed packaging ensures contamination-free delivery. Bulk pricing available for fleet servicing operations.

Engineered for continuous operation in high-RPM applications (up to 5,200 RPM). Micro-polished surfaces reduce break-in time by 40% compared to conventional bearings.
