Installation & Maintenance Tips

Essential Handling Guidelines:
  • Cleanliness: Even minute dust can damage bearings. Maintain a clean environment.
  • Handling: Avoid strong impacts to prevent scars and indentations.
  • Tools: Use presses or heating methods rather than direct hammer taps.
  • Corrosion: Protect from moisture and human sweat; use gloves when possible.

Bearing Mounting Steps

1. Keep bearings unpacked until mounting.
2. Clean shaft and housing thoroughly, checking for burrs or scratches.
3. Inspect dimensions of mounting parts according to technical drawings.
