NTN offers this engine bearing for SUZUKI LT-F 250 QUADRUNNER 2WD, LT-F 250 QUADRUNNER 4WD 1987-2001. The engine’s shafts run on ball or roller bearings in the cases. They carry heavy loads at high revs and eventually develop play.
Races and balls (or rollers) in hardened chrome steel, 100Cr6 type: a very hard steel that withstands the fatigue of millions of engine revolutions.
NTN, the Japanese bearing maker founded in 1918, is the brand chosen by engine specialists such as ProX for their crankshaft bearing kits.
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.
Cross-Mania tip: Heat the cases to remove and fit the bearings without forcing them, and replace the oil seals at the same time.
