Info

  • Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion 
  • Unique SecureBond adhesion process for superior stability between the top and intermediate layers
  • 15% - 30% greater load capacity than traditional bearings
  • Mains and rods are narrowed for large radius crankshafts
  • Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM
  • 0.0005" metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue
  • Mains are 1/2 grooved for uncompromised lower shell load capacity

Item Details

350 Journal

Application

  • High-load, long-duration racing such as circle track, off-road, off-shore, and others that require steel crankshafts

Notes

These bearings are available in the traditional Std, .010, .020 and .030 specs. 

In addition, they are also available in the X.001 and .001 

The X001 bearing is used when 0.001" of additional crank clearance is required.

The 001 bearing is used when the clearance is needed to be tightened up by the one additional 0.001" of reduced clearance.
