Thrust Angular Contact Bearing Croxy

スラストアンギュラベアリング クロクシー
  • ■First in the market, Angular contact bearing for JIS 69 series.
  • ■Enable to downsize ball screw support unit
  • ■Three times higher axial stiffness over standard deep groove ball bearings (ISC data)
  • ■Achieved maintenance free with high quality grease filling and double shielded design
  • ■Easy installation by providing preload combination. (Recommended tightening torque is enclosed with the actual product)
  • ■Available with anti-fretting grease (EA7) and clean grease (LG2)
  • ■Accuracy class:P5

Application example

  • Ball screw support
  • Actuator support
  • Support for Robot arm part
  • Support Unit
  • Chip mounter
  • Reduction gear, etc.

Standard specification (material + grease)

  • High Carbon Chromium Bearing Steel SUJ 2 + Long Life Urea Grease EA7
  • Stainless steel ES-1 + Low particle emission grease LG2
