Overseas operators often hesitate to switch bearing suppliers—until they see the numbers. From South African mines to U.S. rental yards, Dongye Yulin Bearings has delivered measurable savings by focusing on durability and low maintenance. Here are 2 client stories with verified data.

The Problem: A 50t excavator’s boom bearings failed every 3 months due to rock impacts, costing $8,000/month in downtime and parts.
The Solution: Switched to Dongye’s Y-Series spherical roller bearings with:

• 2. U.S. Rental Fleet: 40% Less Maintenance Labor
  • Pre-filled long-life grease (lasts 4,000 hours)
  • Self-lubricating seals (no manual greasing needed)
  • Compatible with Cat/Volvo mounting specs
    The Result:
