718 series Angular Contact Ball Bearings

Structural features: TEDIN precision bearing series based on ISO standard. Rings’ material adopts high purity (electroslag remelting) bearing steel, with special heat treatment process, cold treatment technology and material modification technology, the fatigue life of the series bearings is greatly improved.

Contact Angle: 15° and 25°; Paired assembled bearings is capable to bearing both axial and radial load or combined load.

Cage: The outer ring-guided phenolic resin cloth rubber cage and the roller-guided nylon cage can be selected according to different uses.

to select the Bakelite cage at 500000 ≤ DmN ≤ 1000000 under medium and high speed working conditions;

Nylon cage or Bakelite cage can be used in medium and low speed;

Application: This kind of bearing has a wide range of application. It is mainly used for high speed axial positioning and radial positioning, high precision rotation and other working conditions. For example: CNC lathe spindle, all kinds of grinding machine workpiece shaft, grinding wheel spindle, photovoltaic slicer, vacuum pump, fan, precision transmission machinery and so on.
