MICRO-TEC® II Bearing Isolators

Metallic Bearing Isolator with Micro-Cellular Filter

M Barnwell Services offer the full range of Garlock’s KLOZURE® MICRO-TEC® II Bearing Isolators. MICRO-TEC® II Bearing Isolators provide superior protection for bearings in motors, pumps, and other machinery in excessive airborne contamination environments. This range of bearing isolators offers the same features and benefits as GUARDIAN™ Bearing Isolators, with the extra aid of a Micro-Cellular foam filter to catch any airborne contamination. The Micro-Cellular filter (air filter) improved and strengthened the labyrinth’s ability to trap airborne dust and other contamination particles, consequently making it the first choice seal in Food and Mining Industries.

Features and Benefits of a MICRO-TEC® II Bearing Isolator:

  • The Micro-Cellular filter in the labyrinth pathway traps airborne contamination – able to filter dust and small particulates from entering the bearing chamber
  • Patented Cam-Lock system allows easy installation, no tools needed
  • Cam-Lock design offers superior bore preservation, with NO metal shavings and NO bore scratching
  • Unitizing element removes metal-to-metal contact, stops from separating during operation
  • Non-contact engineered labyrinth design reduces shaft drag, consequently reducing energy usage
  • Engineered labyrinth design traps contamination while retaining bearing lubrication – to IP 66 ratings
  • Non-wearing components – seal properties are not degrading over time, consistent sealing performance
  • Extended bearing life, lifetime bearing protection increases mean time between failure (MBTF)
  • Speedier mean time to repair (MTTR)
  • Eliminates repairs for seal housings and shaft grooving

Micro-Cellular Foam

The silicone-based, closed-cell foam used in the MICRO-TEC® II Bearing Isolators excel at trapping and filtering dust and small particulates from entering the bearing chamber. MICRO-TEC® II has been proven to outlast the others when looking to prolong the service life of bearings in extremely dirty, tough environments.
