PROX Crankshaft Bearing 32x75x20mm for SUZUKI LT-R 450 QUADRACER 2WD 2006-2011

PROX offers this engine bearing for SUZUKI LT-R 450 QUADRACER 2WD 2006-2011. The engine’s shafts run on ball or roller bearings in the cases. They carry heavy loads at high revs and eventually develop play.

What is this bearing made of?

Races and balls (or rollers) in hardened chrome steel, 100Cr6 type: a very hard steel that withstands the fatigue of millions of engine revolutions.

• Open bearing: unsealed, it is lubricated and cooled by the engine oil; clean oil is its best protection.
• C3 / C4 internal clearance: slightly more clearance than normal for a hot engine’s expansion; always refit the original clearance.
• Limit: it dislikes dust and old oil; running short of oil destroys it within minutes.

Why choose PROX?

ProX uses Koyo or NTN bearings, largely made in Japan in OEM factories, with the original internal clearance (C3 / C4).

When should you replace the bearings on your SUZUKI LT-R 450 QUADRACER 2WD?

On competition bikes the main bearings are replaced at every bottom-end rebuild, at the hours recommended by the manufacturer. With the cases open, spin each bearing by hand: the slightest rough spot means it must go.
