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

ATHENA offers this engine bearing for KTM, HUSQVARNA, GAS GAS and HUSABERG 2011-2027. 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 ATHENA?

Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.

When should you replace the bearings on your KTM SXF 350?

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.
