| CD | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
| TBT | Indicates a Triplex Back-to-Back matched arrangement of three bearings, providing maximum rigidity and moment load resistance. |
7032 CD/P4ATBTB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and significant moment loads. The 15° contact angle provides excellent axial load capacity in both directions while maintaining high-speed capability.
Precision Performance: Manufactured to P4A tolerance standards, this bearing ensures minimal vibration and precise rotational characteristics. The phenolic cage offers superior strength and lubrication compatibility, contributing to smooth operation at the limiting speed of 11,000 rpm.
Optimized Material Selection: Constructed from chrome steel for both rings and balls, the bearing delivers high durability and wear resistance. The precision-ground components and optimized ball quantity (22) and ball diameter (25.4mm) ensure even load distribution and extended service life.
