Detailed Engineering Specifications

Engineered for reliability and performance, this deep groove ball bearing features an internal bore diameter of 73mm and an external diameter of 123mm, with a compact width of 5mm. Constructed from high-grade polycarbonate, it offers exceptional chemical resistance and a lower coefficient of friction compared to traditional steel bearings. This makes it ideal for applications where weight reduction, non-conductivity, or resistance to corrosive media is paramount. The precise geometry of the deep groove raceway ensures optimal load distribution and minimizes rotational resistance, contributing to extended operational life and energy efficiency in power transmission assemblies.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing into an undersized housing.Ensure the housing bore is within the specified tolerance for the bearing's outer diameter.
Applying excessive axial load to the bearing during installation.Use a proper bearing press or gentle tapping with a soft-faced hammer to seat the bearing evenly.

Common Applications

  • Conveyor Systems
  • Food Processing Equipment
  • Medical Devices

⚠️ Engineering Warnings

  • Maximum operating temperature for polycarbonate is 130°C; exceeding this may cause deformation.
  • Avoid prolonged exposure to strong solvents that can degrade polycarbonate.
