The bearings that support the crankshaft in the crankcase.

PROX offers this crankshaft bearing kit for HUSQVARNA FC 450, KTM SX-F 450 and GAS GAS MC 450 F from 2016 to 2027. The crankshaft spins on two large bearings in the cases. They take all the engine’s force; after many hours they develop play and vibration appears.

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?

Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.

Recommended hours for a bottom-end rebuild (manufacturer recommendation for the KTM EXC-F, Husqvarna FE 2017-2023):

Racing: every 70 h.
Leisure: every 135 h.
KTM SX-F, Husqvarna FC 2016-2022: racing: every 100 h.
