Installation Procedure

1. Ensure the bearing seat and shaft are clean and free from debris. 2. Carefully align the bearing with the shaft and gently press it into place, ensuring it is seated evenly. 3. If the outer ring requires mounting, ensure a snug fit within its housing, avoiding excessive force that could deform the polycarbonate structure.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive radial or axial load beyond the bearing's specified capacity.Consult the load rating charts and ensure operational loads do not exceed the bearing's design limits to prevent premature failure.
Using incompatible lubricants or cleaning agents that degrade polycarbonate.Refer to the material compatibility guide and use only lubricants and cleaning agents specifically approved for polycarbonate to maintain material integrity.

Common Applications

  • Conveyor Systems
  • Light-duty Robotics
  • Material Handling Equipment

⚠️ Engineering Warnings

  • Avoid prolonged exposure to extreme temperatures beyond polycarbonate's operational range.
  • Do not subject to sharp impacts or severe shock loads that could compromise structural integrity.
