    Description

    Track links wear on the excavator track idlers running surface.  Links and idlers wear as it were in line with each other.  A specified wear value defines when the idler is 100% worn out.  If the hardened section of the running surface is worn, then you should replace the idler.If the sides of the grousers show signs of wear, or the idler rubs against the side of the frame, then the track link is not in line with the idler.  This may be caused by an open frame, worn side shoes, a broken axle or a defective tension device.
    TACK idlers are available for the range of 0.8 to 100 ton. 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 high quality seals .  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.
