An engine bearing: it lets a shaft (crank, gearbox, pump) turn without friction.

NTN offers this engine bearing for YAMAHA YFM 700 GRIZZLY EPS 4WD, YFM 700 GRIZZLY EPS CAMO 4WD, YFM 700 KODIAK 4WD, YFM 700 KODIAK EPS 4WD, YFM 700 RAPTOR 2WD and HONDA XL 600, XL 600 L PARIS DAKAR, XL 600 LM PARIS DAKAR, XL 600 RM, XR 600 1983-2025. 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 NTN?

NTN, the Japanese bearing maker founded in 1918, is the brand chosen by engine specialists such as ProX for their crankshaft bearing kits.

When should you replace the bearings?

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.
