Related Product Features:
  • Integrated high-strength bolt shaft made from 40Cr carbon steel with 45-50 HRC hardness for direct installation without additional shaft parts.
  • Precision-ground roller body constructed from premium GCr15 bearing steel with 58-62 HRC hardness for superior durability.
  • Built-in double-sided rubber seals (2RS) effectively isolate dust, moisture, and contaminants for maintenance-free operation.
  • Curved roller profile designed to match U-groove guide rails ensuring stable contact and balanced load distribution.
  • Suitable for heavy-duty applications in automated production lines, logistics equipment, and engineering machinery.
  • Interchangeable with industry equivalents including INA KR19 and SKF CF10BUU stud roller bearings.
  • Pre-filled with lithium-based grease for immediate use without additional lubrication under normal conditions.
  • Optimized for light-load, low-to-medium speed scenarios with a limit speed of approximately 8000 r/min.
FAQs:
  • What is the difference between U-groove and V-groove in this series?
    U-groove is suitable for flat-bottomed guide rails, while V-groove matches V-shaped guide rails—both can be customized according to the equipment's guide rail structure.
  • Can these bearings be used in high-speed scenarios?
    They are designed for light-load, low-to-medium speed scenarios with a limit speed of approximately 8000 r/min under grease lubrication, and are not recommended for high-speed rotating equipment.
  • Is the lubrication of these bearings maintenance-free?
    Yes, they are pre-filled with lithium-based grease and sealed with ZZ, so no additional lubrication is needed during their service life under normal light-load conditions.
