Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this deep groove ball bearing boasts an inner diameter of 77mm, an outer diameter of 157mm, and a width of 36mm. The advanced polycarbonate construction provides exceptional chemical inertness and resistance to moisture, making it ideal for applications where traditional steel bearings may degrade. Its inherent lubricity and low friction coefficient contribute to extended service life and reduced energy consumption in rotating machinery. The material's non-conductive nature also makes it a superior choice for electrical isolation requirements.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto the shaft or into the housing without proper alignment.Ensure perfect alignment of the bearing with both the shaft and the housing before applying any pressure. Use a bearing installer tool if available.
Overheating the bearing during installation, especially if using heat for mounting.If heat is necessary, use controlled induction heating or an oil bath at precisely specified temperatures for polycarbonate bearings. Avoid direct flame or excessive temperatures.

Common Applications

  • Food and Beverage Processing Equipment
  • Chemical Handling Systems
  • Water Treatment Machinery
  • Medical Devices
  • Conveyor Systems in Corrosive Environments

⚠️ Engineering Warnings

  • Not suitable for applications with extreme shock loads or abrasive particle contamination without additional sealing.
  • Maximum operating temperature and load ratings for polycarbonate should be consulted and adhered to for optimal performance and longevity.
