ISO-GARD® Bearing Isolators

Non-Metallic Bearing Isolator

M Barnwell Services offer the full range of Garlock’s KLOZURE® ISO-GARD® Bearing Isolators. They provide superior bearing protection for motors, pumps, and bearing supported industrial machinery which must perform in the toughest environments.

ISO-GARD® Bearing Isolators are constructed using a filled PTFE material which provides excellent chemical resistance.ISO-GARD® Bearing Isolators

Features and Benefits of an ISO-GARD® Bearing Isolator:

  • Filled PTFE construction offers superior chemical compatibility
  • Unitized construction will not come apart at the time of installation, easy by-hand installation – no need for arbor press or other tools
  • Available in a wide selection of configurations (see below)
  • Engineered labyrinth design exclude contamination while retaining bearing lubrication – to IP 55 ratings
  • Non-contact engineered labyrinth design reduces shaft drag, consequently reducing energy usage
  • Compliant with various industry standards
  • Non-wearing components – seal properties are not degraded over time, consistent sealing performance
  • Extended bearing life, bearing protection increases mean time between failure (MBTF)
  • Speedier mean rime to repair (MTTR)
  • Eliminates repair for seal housings and shaft grooving
