Special Ball Bearing

特殊ボールベアリング

Used in locations where low torque is required, as a high speed angular ball shaft with lubricant d.n (d: diameter of shaft, n: Rpm),
up to 600.000 means relatively less load but in high speed. Less of noise compare to other type.
Furthermore, due to light of equipment, there are no burning/combustion mark although in highly speed.

Materials

  • Thermo hardening resin with absorption phenolic impregnated fabric laminate

  • Thermoplastic 66 nylon, poly acetyl, etc

Features

Used in locations where low torque is required, as a high speed angular ball shaft with lubricant d.n (d: diameter of shaft, n: Rpm), up to 600.000 means relatively less load but in high speed.

  • Due to light of equipment, there are no burning/combustion mark although in highly speed.

  • Particularly substrate phenol, because of 2-3% oil contain by weight showing the tremendous power during lubrication.

  • Less of noise compare to other type.

  • By maintenance tool of phenol, equipment can be operated continuously up to 130 ℃.

  • The precision, strength and heat resistance in its characteristic of lubricant have been proved.

THE MAIN USE

High frequency precision bearing, used in scales, computer, spindle (lathe, milling and grinding), airplane, machines, printers, high frequency motor, etc.
