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 when used with our NP Pillow Blocks and Flange Blocks. Fluidline linear bearings exhibit a stunning operational smoothness when matched with our 300 stainless shafting (also FDA/USDA compliant). Standard pillow block and flange block assemblies are also available.
NOTE: Bearings available in closed version only.

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.
