The Perfect Oilless SGO

Graphite Plugged Bearing
Self Lubricating Bearing

SGO #500

압입형 베어링

It is a self-lubricating bearing with graphite plugged to base metal. Fine particles of solid lubricant create lubrication film on the motion part, when friction is occurred, and the bearing can achieve excellent self-lubrication and abrasion resistance under dry lubricating condition.


Characteristics

  • Can achieve excellent performance in high-load and low-speed motion, while lubrication is not applied.
  • Can achieve excellent abrasion resistance in an environment where lubrication film is difficult to be formed such as reciprocating motion, angular pitching motion, and frequent stop motion.
  • Can be used in a condition where tolerance is not precise or working condition is rough.
  • Relatively resistant to inflow of foreign substance,corrosive and chemical environment.
  • Standards parts and custom-made parts available.
