Detailed Engineering Specifications

Specified by design engineers worldwide, this polycarbonate deep groove ball bearing (39mm ID x 155mm OD x 9mm W) delivers superior performance in corrosive or chemically aggressive settings. The inherent dielectric properties of polycarbonate eliminate concerns regarding electrical conductivity, making it ideal for applications where stray currents are a risk. Its low friction coefficient and excellent wear resistance ensure smooth operation and extended service life, even under moderate load conditions. This bearing is designed for applications requiring a non-magnetic solution and where weight reduction is a critical design factor.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening during installation leading to premature deformation of the polycarbonate raceway.Utilize a controlled press or bearing heater for installation and apply only the necessary force to seat the bearing.
Exposure to extreme temperatures exceeding polycarbonate's operational limits, causing material degradation.Verify operating temperature range of the specific polycarbonate grade against application requirements before deployment.

Common Applications

  • Chemical processing equipment
  • Food and beverage machinery
  • Medical devices

⚠️ Engineering Warnings

  • Not suitable for high-impact or heavy-load applications where metal bearings are typically required.
  • Avoid prolonged exposure to strong solvents or UV radiation, which may degrade polycarbonate.
