Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the wrong race during installation, leading to brinelling or premature failure.Always apply force evenly to the race that is being pressed into or onto its mating component (outer race for housing, inner race for shaft).
Insufficient lubrication or using incompatible lubricant, causing increased friction and wear.Consult the bearing manufacturer's recommendations for appropriate lubricant type and quantity for the operating conditions.

Common Applications

  • Lightweight Power Transmission Systems
  • Corrosive or Chemically Active Environments
  • Aerospace and Automotive Components

⚠️ Engineering Warnings

  • Aluminum 6061 bearings may have lower load capacities compared to hardened steel bearings; select based on application requirements.
  • Avoid excessive shock loads or impact, as this can damage the bearing races and rolling elements.
