Crawler crane Link belt LS138HII track roller

Crawler crane Link belt LS138HII track roller transmits the weight of the crawler crane to the ground and rolls on the crawler. In order to prevent derailment, Crawler crane Link belt LS138HII track roller should also be able to prevent the track from moving sideways against it.

Crawler crane Link belt LS138HII track roller often works in muddy water, ash and sand, and bears the strong impact.And Crawler crane Link belt LS138HII track roller rim wear-resistant, reliable bearing seal, low rolling resistance

1. Detail:

Product Name: Crawler Crane Fushun QUY160C Track Roller / Bottom Roller /Lower Roller

Material: 40Mn2

Technique: Forging

Heat Treatment: Overall hardening and tempering, surface hardening

2. Production Process

3. Quality:

1). Roller Body: Material is 40Mn2 ---hard wearing,  so, that can extend the roller's service life.

2)Bushing: 100% fine cooper Bushing, instead of duplex metal(Iron and Cooper). The thickness of bushing is 6mm-10mm.

3）Pin: The material is 42Cr

4）Floating seals: the size of Floating seals must 100% match the roller. If not, the oil will spilling.

5）The most important process is Hardening and Tempering if the rollers are not undereardening and tempering, the Mechanical  Properties, Yield Strength and Tensile Strength will not be good, the roller will be slip easily.
