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
Structural Features: The design of small balls enable 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 special technology of heat treatment, cold treatment and material modifications leads to the dramatic increase in the fatigue life of bearing.
Contact Angle: 40°. The special treatment for the dimension deviation of outer ring causes the clearance between outer diameter of outer ring and the inner diameter of 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 ball,
• Grease : DmN≤650000 (that is, limit speed N≤650000/Dm
• Oil (minimum) : DmN≤850000
when the rolling elements are ceramic ball,
• 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.
