Category: BTR10 Series High-Speed Thrust Ball Bearing Angular Contact Thrust Ball Bearing
Material: SHX bearing steel with high purity
Rolling Element: Steel Balls, Ceramic Balls
The design of small balls enables the bearings to have high-speed performance, high rigidity, and low heat. The rings are made of IQ-graded bearing steel with high purity. The unique technology of heat treatment, cold treatment, and material modifications dramatically increase bearing fatigue life.
40°. The special treatment for the dimension deviation of the outer ring causes the clearance between the outer diameter of the outer ring and the inner diameter of the housing, which enables the bearings to support the radial loads only. The back-to-back arrangement is generally used.
Cage: Nylon (rolling-element guided)(rolling-element guided)
when the rolling elements are steel balls,
• Grease: DmN≤650000 (that is, limit speed N≤650000/Dm
• Oil (minimum): DmN≤850000
when the rolling elements are ceramic balls,
• Grease: DmN≤750000 (that is, limit speed N≤750000/Dm
• Oil (minimum): DmN≤950000
Applications: usually used with the cylindrical roller bearings; mainly used for high rotational speed and high axial rotating accuracy, etc., for example, CNC universal grinding machine large wheel spindle, CNC lathe spindle, Centerless grinding wheel, bearing raceway grinding wheel spindle, high precision machinery, etc.
