Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this 71mm inside diameter, 73mm outside diameter, and 7mm width deep groove ball bearing is constructed from high-grade polycarbonate. This advanced polymer provides a significantly lower specific gravity compared to traditional steel bearings, reducing overall system weight without compromising structural integrity under moderate loads. Its inherent non-corrosive nature makes it ideal for applications exposed to moisture, chemicals, or harsh environmental conditions. The smooth raceway surfaces ensure low friction and efficient rotational performance, suitable for applications requiring quiet operation and electrical insulation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, especially using impact tools.Use a controlled press or a specialized bearing installation tool to apply even pressure. Avoid hammering or direct impact on the bearing races.
Incorrect shaft or housing fit, leading to binding or premature wear.Verify that the shaft and housing dimensions meet the specified tolerances for the bearing. An interference or clearance fit that is too tight or too loose will compromise performance and lifespan.

Common Applications

  • Lightweight conveyor systems
  • Food processing equipment
  • Medical devices
  • Corrosive chemical handling machinery
  • Electrical insulation applications

⚠️ Engineering Warnings

  • Not suitable for high-impact or heavy shock load applications.
  • Operating temperature range must be adhered to; excessive heat can degrade polycarbonate.
  • Avoid exposure to aggressive solvents that may attack polycarbonate.
