Fluidline Linear Bearings

LM76 Fluidline Linear Bearings are an internally lubricated thermoplastic polyester
which provides for enhanced wear and chemical inertness. Fluidline Linear bearings
are
self-lubricating, low friction, lightweight, low wear material is excellent in applications
which require FDA, USDA and 3A compliance. This bearing is available in standard
off-the-shelf sizes which are drop-in replacements for all inch (metric available upon request)
linear ball bearings. Fluidline linear bearings feature excellent washdown resistance.
Fluidline linear bearings exhibit a stunning operational smoothness when matched with our
 ceramic coated aluminum shafting  (also FDA/USDA compliant). Standard pillow block
and flange block assemblies are also available. NOTE: Bearings available in closed
version only. Special Designs Welcome: $ 20.00 minimum

Chemical Resistance Chart

  • High mechanical strength, stiffness and
    hardness

  • Very good creep resistance Low and constant coefficient of friction

  • Excellent wear resistance (comparable to
    or even better than nylon grades)

  • Very good dimensional stability (better than polyacetal)

  • Physiologically inert (suitable for food contact)

  • Excellent stain resistance Better resistance to acids than nylon and polyacetal

  • Good electrical insulating properties Good resistance against high energy radiation
    (gamma-and X-rays)

K Factor or Wear Rate is expressed by a number. The lower the number, the better the wear rate.
For instance, popular Delrin™ AF has a K Factor of 60.
