Top roller

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

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