KOMATSU IDLER D11N

TACK idlers for bulldozers are produced in compliance with OEM standards. TACK has selected high-quality steel, for example, because this alloy hardens well and is tough. Because bulldozers do a lot of mobile work, there is a lot of contact between the front idler wheel and the track link. Experience has taught us that it is very important to subject the idlers’ running surface to a specific process; for this, we apply a special molding method to prevent the formation of gas in the material. Moreover, a specific heat treatment on the surface ensures better depth hardening and therefore a longer service life. We use a higher molding temperature and take extra time to allow the molded material to cool down in a controlled way. This prevents fissures from forming during the process.
