Description

This top roller is a vital component of the QUY50 crawler crane's undercarriage system, designed to support the upper track and ensure smooth operation. It features a double-flange structure to prevent track derailment and enhance stability.

  • Performance: Integrated with precision sealed bearings and floating oil seals, providing exceptional resistance to dust/water ingress for maintenance-free service (grease replenishment only during major overhauls).

  • Material & Treatment: Manufactured from 42CrMo alloy steel with quenched & tempered surface (HRC 50-55 hardness), balancing high strength and wear resistance.

  • Operating Conditions: Suitable for harsh environments (e.g., mining, construction) with frequent shock loads. Regular inspections of track tension (recommended: 50-70mm) and alignment are required to maximize service life.
