Track roller for crawler crane Link belt LS138HSL

Track roller for crawler crane Link belt LS138HSL is used to support the weight of the crane body and roll on the track shoes so that the machine travels along the tracks shoes. Track roller for crawler crane Link belt LS138HSL is also used to hold track shoes so that it does not slip along the transverse direction and forces the track to slip on the floor when turning. In some special load conditions or arm conditions, force only on some track rollers, so the arrangement of track rollers is middle sparse and two ends dense. Because Track roller for crawler crane Link belt LS138HSL often work in the mud and other difficult conditions, and bear a strong impact, so,it is required to seal reliably, with high strength and stiffness.

Application For Track Roller：Track roller for crawler crane Link belt LS138HSL is used to support the weight of the crane body and roll on the track shoes so that the machine travels along the tracks shoes. Track roller for crawler crane Link belt LS138HSL is also used to hold track shoes so that it does not slip along the transverse direction and forces the track to slip on the floor when turning.

2. Advantage:

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

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

C. Pin: The material is 42Cr

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

E. 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.
