Category: 72 Series Bearing High Precision Angular Contact Ball Bearings (Standard)
Rolling Element: Steel Balls, Ceramic Balls
Sealed: Yes
the rings are made of bearing steel with high purity (Electro-slag remelting ESR). The unique technology of heat treatment, cold treatment, and material modifications dramatically increase bearing fatigue life.
Contact Angle: 15°and 25°. Paired bearings can support axial and radial loads.
Cage: Bakelite (outer-ring guided), Nylon (rolling-element guided), Brass, etc.
• The Bakelite cage is recommended for the medium or high speed; 500000≤DmN≤1000000
• The nylon or Bakelite cage is recommended for low or medium speed.
Speed Factor: take the outer-ring-guided Bakelite cage as the standard
• Grease: DmN≤1000000 (that is, limit speed N≤1000000/Dm
• Oil (minimum): DmN≤1500000
They are mainly used for precise axial and radial positioning with medium or high rotational speed, high-precision rotation, etc. For example, CNC lathe spindle, grinding machine spindle, grinding wheel spindle, solar machine cutting machine, vacuum pump, precision transmission machinery, etc.
