SUMITOMO SH200 Excavator Bottom Track Roller 52-58HRC

Cylindrical elements are indispensable components of conveyor systems - available in various models and readily supplied in abundant quantities. They reliably bear the combined load of the conveyor belt and the materials it transports. Their significance is underscored by two critical metrics:

• Account for 35% of a conveyor system's total cost
• Generate over 70% of operational friction

These elements are crafted from two primary material categories: metallic and polymeric.

• Utilizing thermal treatment processes for outstanding mechanical characteristics, exceptional strength, and enhanced resistance to deformation
• Surface hardness (HRC40-55) minimizes wear and prolongs lifespan
• Designed for secure attachment and efficient grousing, handling heavy loads up to 50 tons
• Materials include 40Mn2, 40MnB, 50Mn depending on working conditions
• Normalized with precision forging before heat treatment for surface hardness of HRC52-6
• Hardened layer depth reaches 7-10mm (HRC45) for higher durability and impact resistance
• High quality floating seals and lubricating system adapt to different climates (-45℃~120℃)

• World-class quality
• Factory direct sales with competitive pricing
• 35 years' experience in Excavator & Bulldozer spare parts manufacturing
• Flexible payment terms (T/T, L/C)
• Fast delivery within 30 days
• Professional sales team and quality inspection
• Comprehensive after-sale services
