JEGS Rod Bearings

JEGS Rod Bearings

Available in a Performance or High-Performance series, JEGS Engine Rod Bearings are constructed of two layers: high-strength steel and a bonded layer of silicon, tin, and copper in an aluminum matrix. Properties are maintained throughout for consistent and reliable output, embedability, and conformability. Additionally, micro-fine machined High-Performance Bearings are narrowed for large radii cranks and have chamfered oil holes. Bearings are sold in engine sets for Chevy and Ford applications.

High Load Capacity
With 8,000 psi load capacity, aluminum silicon bearings withstand the stress of high-performance engines. All JEGS Bearings are made from the same metallurgical alloy so cars that have standard bearings benefit from this alloy used in race engines.

Temperature Resistance
This alloy's melting/fatigue point is 450°+ F (100° more than the thin babbitt overlay of tri-metal bearings). This means extra protection against localized overheating due to misalignment, detonation, overloading, loss of coolant, etc.

Particle Embedability
More than half of engine bearing failure is caused by metallic particles that scratch crank journals and weaken or tear thin bearing overlays. Because aluminum silicon overlay is much thicker than babbitt in tri-metal bearings (0.015" vs. 0.0008"), it provides 18 times more embedability to trap particles to prevent crank journal scratches. This is especially true for particles over 0.0004", which cause most of the damage.

Conformability
The thicker aluminum silicon layer allows bearings to better conform to problems, such as metal-to-metal contact due to misalignment or connecting rod stretch. Greater conformability also means fewer bearing failures.

Control of Wall Tolerance
Bearing-to-journal clearance on main and connecting rod bearings is affected by several factors. We've alleviated concerns about inconsistent shell-to-shell bearing wall thickness by using statistical control methods to minimize wall thickness variation. JEGS Engine Bearing thickness varies no more than 0.00010". Other manufacturers produce bearings with wall thickness at the crown that varies as much as 0.00025".
