Core Advantages of Our Kobelco CKS800 Top Roller

1) Roller Body: Material is 40Mn2, 50Mn round steel, which can extend the roller’s service life.  Some factories are #45 square steel.  This material price is much lower, and its Mechanical Properties are so bad.

2 )Bushing: 100% fine copper bushing, the thickness of the bushing is 6mm-10mm.

3) Shaft: our material is 42Cr; others use 45# steel.

4)Floating Seals: The size of the floating seals must 100% match the roller.

5)The most important process is Quenching & Tempering. If the rollers are not under quenching & tempering, the mechanical properties, yield strength, and Tensile Strength will not be good, and the roller will slip easily.  The other factory sometimes does not temper, just quenching.

Each stage is carefully supervised to maintain consistent quality. Our objective is to deliver a crane top roller that meets demanding site conditions while offering long-term operational reliability.
