Detailed Engineering Specifications

Manufactured under strict quality controls, this deep groove ball bearing boasts an inside diameter of 68mm, an outside diameter of 186mm, and a width of 33mm. The high-performance polycarbonate material provides excellent chemical resistance to many solvents and lubricants, along with inherent dielectric properties making it ideal for electrically sensitive environments. Its low coefficient of friction ensures efficient power transmission with reduced energy loss. The bearing is designed for moderate load capacities and medium-speed operation, suitable for applications where weight and non-conductivity are critical factors.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to brinelling or cracking of the polycarbonate races.Use a proper bearing installation tool or press, applying force only to the ring being fitted to the shaft or housing. Ensure smooth, even pressure.
Contamination of bearing surfaces with dirt or abrasive particles before or during installation.Keep the bearing in its protective packaging until ready for installation. Clean all surrounding components and tools thoroughly before handling the bearing.

Common Applications

  • Lightweight conveyor systems
  • Robotics and automation equipment
  • Medical device components

⚠️ Engineering Warnings

  • Not suitable for heavy shock loads or high-frequency vibration applications.
