UltraLAST 121®

Controlled Porous Sintered Silicon Carbide

JJISCO UltraLAST alpha sintered controlled porous silicon carbide provides alpha grade plus performance where additional fluid reservoir lubrication is required. Our UltraLAST components include:

Guide Bearings • Journal Bearings • Large Seal Faces • Sleeve Bushings • Thrust Bearings • Wear Rings

JJISCO UltraLAST 121 silicon carbide offers added lubricity with leading technology for controlled pore size and distribution. Where added system fluid lubrication is required for increased wetting between the shaft and mating component, this grade assists in optimizing performance. Below are typical property values:

PROPERTIES UltraLAST 121
HARDNESS (Knoop) 2800
MATERIAL COMPOSITION Alpha Sintered Porous SiC
DENSITY (gm/cm3) 2.90

JJISCO UltraLAST121 offers superior performance by enabling additional lubrication in the porous material:

  • Enhanced lubricity through fluid retention
  • Superior hardness and high strength
  • High abrasion and wear resistance
  • Extreme corrosion resistance
  • Excellent thermal shock resistance
