More than 300 configurations of single flange,double flange and Inner fiange rollers suitable for excava-tors,bulldozers and track-type machines. Forged roller shell made of quality steel refines metal gains to formforge flow line with reasonable distribution as stress characteristic.

Heat-treatment,which is integrate heating and surfacespray cooling under high pressure, to improve internal mechanical properties to prevent deformation under heavy load , meanwhlle high surface hardness and deep harden depth result in longer life.Heat- treated and induction hardened shaft made of quality steel to guarantee resistance to wear and heavy load.
