7016 CDGB/P4A Bearing Product Overview & Core Advantages
The 7016 CDGB/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Operating under P4A tolerance class, this bearing delivers superior dimensional stability and running accuracy. Its 15° contact angle is optimized for handling combined loads, efficiently supporting significant radial loads alongside substantial axial loads in one direction. The Universal Matchable (SU) design allows for precise preload configuration when mounted with other bearings, while the phenolic cage and factory-applied lubrication enable reliable high-speed operation up to 17,000 rpm.

| P4A | High precision tolerance class | Exceptional running accuracy and dimensional stability |
7016 CDGB/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore tolerance: -0.004mm to 0, OD tolerance: -0.004mm to 0) ensuring minimal runout and vibration in high-speed applications.
Optimized Load Capacity: The 15° contact angle and chrome steel construction provide excellent combined load capacity with dynamic radial load rating of 14,625 lbf and static radial load rating of 13,725 lbf.
High-Speed Performance: The phenolic cage offers superior strength-to-weight ratio and smooth operation at limiting speeds of 17,000 rpm, while the pre-applied lubrication ensures consistent performance across the operating temperature range (-30°C to 110°C).
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be precisely arranged in sets of three to achieve optimal preload conditions for specific application requirements.
