4. When to replace tensioner pulley?

It is recommended to replace the tension pulley in zip fasteners in the following situations:

  • Visible signs of wear, such as cracks or deformation
  • Loss of tension control, resulting in zipper malfunction
  • Excessive noise or irregular movement during zipper operation
  • Frequent zipper jamming or slippage
  • Regular maintenance schedule suggests replacement

5. How to choose or customize the right tension pulley?

Choosing or customizing the right tension pulley for your specific needs requires consideration of various parameters and practical conditions:

  • Material composition: Selecting a durable and corrosion-resistant material, such as stainless steel or reinforced polymer, based on the environment and application requirements.
  • Pulley diameter and width: Determining the appropriate size to ensure proper engagement with the zipper mechanism and optimal tension distribution.
  • Bearing type: Choosing the suitable bearing type, such as ball bearings or needle bearings, to minimize friction and enhance pulley performance.
  • Tension adjustment mechanism: Assessing the availability of adjustable tension features to accommodate different fabric thicknesses or user preferences.
  • Compatibility and installation: Checking the compatibility of the tension pulley with the existing zipper structure and considering the ease of installation.
