Product Spotlight: ASTCRG Series Structure, Filament Wound Self-Lubricating Bushings

April 23, 2018 by Christine Berlly

Bushings (also referred to as plain bearings, plane bearings, sleeve bearings or linear sleeve bushings) operate with sliding motion between the moving surfaces. Today, we’re taking a look at the ASTCRG Series Bushings, a filament wound, self-lubricating option.

The ASTCRG Series Bushings are high-load plastic compound bushings with two basic layers. The outside is an enhanced, high-temperature, epoxy resin with wound glass fibers encapsulated within the resin. The inside sliding layer has continuously wound PTFE fibers, a separate special fiber, and another lubricant encapsulated throughout.

The ASTCRG series features:

  • Very high load capacity
  • Excellent resistance to impact
  • Very good chemical resistance
  • Low friction and good anti-wear properties

Some typical applications for the ASTCRG Series include:

  • Hydraulic cylinder pivots
  • Construction machinery arm bushes
  • Boom lifts, scissor lifts
  • Cranes, material handling equipment
  • Port machinery
  • Package machine
