Bearing Eccentricity:  BMW Factory 439/440 rod bearings
 +
<br>
 +
===BE Bearings===
 +
====Production and Composition====
 +
'''Manufacturer:  '''Clevite<br>
 +
'''Composition:'''  Trimetal lead/copper<br>
 +
'''Coating:'''  Clevite TriArmor®<br>
 +
'''Part Number:  '''SP1527HK<br>
 +
'''Target Market:  '''Extra clearance OEM replacement
 +
 +
BE Bearings are a full custom rod bearing designed and manufactured by Clevite.  Clevite manufactures the bearings to the BE Bearing specifications.
 +
 +
The composition is a standard babbit lead/copper bearing with additional Clevite Tri-Armor non-friction coating. They are soft faced, and easy on the crankshaft, and compatible with stop-start vehicles.
 +
 +
'''Lead/Copper, Tri-Metal design'''
 +
Tri-Metal, lead/copper are considered the world's best bearings.  The steel backing is coated with copper, then topped with a soft lead.  The lead is embeddable, meaning small particles can embed themselves in the lead without causing any damage to the crankshaft.  Look in the best automotive engines, and you're likely to find a Tri-Metal bearing design.<br>
 +
 +
'''Used Oil Analysis (UOA)'''
 +
BE Bearings chose the Tri-Metal lead/copper bearings to track the metals in the UOA like Blackstone.  BE Bearings wanted their bearings to show up in the UOA, and another reason they chose the Tri-Metal, lead/copper design.<br>
 +
 +
'''Clevite TriArmor® coating'''
 +
For increased bearing life and durability, BE Bearings chose to add the Clevite TriArmor coating.  TriArmor is a low-friction coating offered directly from Clevite with a Clevite warranty.  It's ideally suited for start-stop engines and protects the crankshaft and bearings at critical times of low oil pressure and/or during start up.<br>

BE Bearings

Production and Composition

Manufacturer: Clevite
Composition: Trimetal lead/copper
Coating: Clevite TriArmor®
Part Number: SP1527HK
Target Market: Extra clearance OEM replacement

BE Bearings are a full custom rod bearing designed and manufactured by Clevite. Clevite manufactures the bearings to the BE Bearing specifications.

The composition is a standard babbit lead/copper bearing with additional Clevite Tri-Armor non-friction coating. They are soft faced, and easy on the crankshaft, and compatible with stop-start vehicles.

Lead/Copper, Tri-Metal design Tri-Metal, lead/copper are considered the world's best bearings.  The steel backing is coated with copper, then topped with a soft lead.  The lead is embeddable, meaning small particles can embed themselves in the lead without causing any damage to the crankshaft.  Look in the best automotive engines, and you're likely to find a Tri-Metal bearing design.

Used Oil Analysis (UOA) BE Bearings chose the Tri-Metal lead/copper bearings to track the metals in the UOA like Blackstone.  BE Bearings wanted their bearings to show up in the UOA, and another reason they chose the Tri-Metal, lead/copper design.

Clevite TriArmor® coating For increased bearing life and durability, BE Bearings chose to add the Clevite TriArmor coating.  TriArmor is a low-friction coating offered directly from Clevite with a Clevite warranty.  It's ideally suited for start-stop engines and protects the crankshaft and bearings at critical times of low oil pressure and/or during start up.
