The GGB Designer’s Handbook for Hydropower Bearings

July 6, 2010


GGB HPM and HPF bearings for hydropower and fluid power applications

GGB Bearing Technology, formerly Glacier Garlock Bearings, now offers a 32-page designer’s handbook for its greaseless, maintenance-free HPM and HPF® filament wound bearings for hydropower applications such as turbines, gates and valves, to provide designers with the comprehensive technical information on the characteristics of these high load, self-lubricating bearings.

GGB Maintenance-Free Bearings Offer Greater Benefits

Combining the self-lubricating properties of PTFE with the strength and stability of a glass-fiber-filled epoxy resin backing, HPM and HPF® filament wound bearings offer the following advantages:

  • Maintenance-free operation with no additional lubrication required
  • High static and dynamic load capacity
  • Resistant to impact, shock and edge loadings
  • Low friction and wear rate to offer a longer service life
  • Suitable for rotating, oscillating and linear movements
  • Dimensionally stable with low water absorption making them suitable for use in seawater
  • Excellent corrosion resistance
  • Environmentally friendly – compliant with EU RoHS legislation
  • 75% lower weight than equivalent size metallic bearings
  • HPM bearings can be machined to the required inner or outer diameter.

Covered in the new publication are general characteristics of the bearings, their structure, composition and properties, mating materials, lubrication, lifetime estimation, installation, recommended dimensions, ISO tolerances and data sheet for bearing design.
