SGO #500
It is a plain 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 | Plain Bearing
- 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.
