Long wear parts@ supply high quality Caterpillar Front Idler/Caterpillar Idler Group/ Caterpillar Track Idler/ Caterpillar Idler Wheel/ Caterpillar Idler Roller.
Long wear parts@ idler wheel is forged from high-quality alloy steels—such as 35Mn, 35MnB, or 40Cr—offering exceptional strength and toughness to resist fracture.
The wheel tread undergoes intermediate-frequency induction hardening, achieving a hardness of HRC 52–60; the hardened layer is uniform, ensuring excellent wear resistance without spalling.
Precision machining ensures superior coaxiality, resulting in smooth, vibration-free operation that minimizes track wear.
The wheel body features an optimized structural design that provides excellent resistance to both impact and fatigue, ensuring stable performance even under the heavy-load conditions typical of mining operations.
Reliable sealing effectively prevents the ingress of dust and water, thereby extending the service life of the internal bearings and bushings.
Long wear parts@idler groups are compatible with Caterpillar(CAT) /Komatsu /ESCO /Sany /Doosan/ Hyundai/ Hitachi/ Liebherr/ Hensley /VOLVO/ Liugong/ Xugong/ MTG/JCB/H&L/Combi/ Case/John deere/Kobelco/Fiat/Sumitomo/ Bobcat/Samsung machines and so on.
