Check before ordering

• Dimensions (inner × outer × width): 30 × 62 × 16 mm

WOSSNER offers this engine bearing for KTM EXC 125, EXC 200, SX 125, BETA RR 250, RR 450, RR 525 and HUSQVARNA TC 125 from 1998 to 2017. 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 WOSSNER?

Wössner, the German company founded by a former racer, forges its own parts: design and manufacturing are controlled end to end.

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.
