SGO Develon

Sliding Bearing

Develon bearing has been improved to make SGO be the No. 1 bearing manufacturer in Korea and the world. This sliding bearing is steel-backed sintered metal bearing with excellent wear-resistance for heavy load and low/mid velocity.
Sintered materials (1~1.2mm) including Cu, Fe, Ni, Sn, MoS2, Graphite and oil impregnated pores are spotlighted as a new generational sliding bearings.


Characteristics

  • Since solid lubricant is evenly distributed, it can be used for any motion direction.
  • Since sintering and solid lubricant are applied, lubrication is multiplied, which can be used in high speed.
  • Since it has lower heat expansion rate compared to general non-metal bearing, temperature change is low and it maintains high accuracy.
  • Since heat processing is applied on external material, it is suitable for high load and it can be used without lubrication.
  • Additional oil impregnation is needed to prevent oil washing after it has been stored for a long time or additional processing has been applied.
  • Standards parts and custom-made parts available.
