7019 ACD/HCP4ATBTC

• 7019: Basic bearing series and size designation (Bore: 95mm, OD: 145mm, Width: 72mm)
• ACD: Angular Contact design with a 25° contact angle
• HCP4A: High-Precision P4A tolerance class with enhanced running accuracy
• TB: Triplex Back-to-Back matched bearing arrangement
• T: Identifies the phenolic cage material
• B: Indicates moderate preload (Class C)
• C: Specifies ceramic ball material

Exceptional Rigidity & Load Capacity: The triplex back-to-back arrangement of three bearings creates an extremely rigid bearing system capable of handling significant moment loads and combined radial and axial loads. With a radial dynamic load rating of 37,125 lbf and static load rating of 51,300 lbf, this configuration provides robust support for heavy-duty applications.

High-Speed Performance: The combination of ceramic balls and phenolic cage enables superior high-speed operation, achieving a limiting speed of 15,000 rpm. The reduced weight and excellent thermal properties of these materials minimize centrifugal forces and heat generation at elevated speeds.

Precision Engineering: Manufactured to P4A tolerance class with tight dimensional tolerances (bore and OD tolerance: -0.004mm to 0), this bearing ensures precise rotational accuracy and minimal runout. The 25° contact angle is optimized for handling substantial axial loads while maintaining radial load capacity.

Thermal Stability: The phenolic cage material provides excellent dimensional stability across the operating temperature range of -30°C to 110°C, maintaining consistent performance under varying thermal conditions.
