Bulldozer Front Idler Excavator track Idler Excavator Undercarriage Parts Front Idler Assy
SZC idlers are available for the range of 0.8 to 100 ton. The most recent automated design and manufacturing process guarantees SZC quality. We produce the idlers using selected quality steel alloys and we apply induction hardening for optimal performance in extreme weather conditions. We assemble them using our own designed seals in accordance with the most recent quality standards. We perform the final assembly of the idlers on a specially set-up production line with inspection points to guarantee the quality. For instance, an automatic oil filling system, but also fissure and leak tests.
SZC idlers for bulldozers are produced in compliance with OEM standards. SZC 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.
