7216 ACDGB/P4A Bearing Product Overview & Core Advantages
The 7216 ACDGB/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate combined loads, it efficiently handles significant radial loads alongside substantial axial loads in one direction. Manufactured to P4A tolerance class with Universal Matchable (SU) designation, this bearing enables precision-matched sets for optimal preload and performance in demanding configurations. Its phenolic cage and factory-applied lubrication contribute to smooth operation at high speeds while maintaining dimensional stability across a wide temperature range.

7216 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 25° contact angle and optimized raceway geometry provide exceptional stiffness and enable the bearing to handle substantial combined loads (18428 lbf dynamic radial rating). The precise ball guidance ensures stable operation under varying load conditions.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore tolerance: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration for high-speed applications up to 28,000 rpm.
Thermal Stability & High-Speed Capability: The phenolic cage offers excellent dimensional stability across the operating temperature range (-30°C to 110°C) while reducing centrifugal forces at high speeds. Factory-applied lubrication ensures immediate operational readiness and extended service life.
Universal Matching Capability: As a Universal Matchable (SU) bearing, the 7216 ACDGB/P4A can be precision-paired with identical bearings to create optimally preloaded sets, eliminating the need for complex adjustment procedures during installation.
