S71914 ACE/P4ADT Bearing Product Overview & Core Advantages
The S71914 ACE/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. This metric duplex tandem (DT) arrangement bearing set is preloaded, delivering high rigidity and precise rotational characteristics. Its primary advantage lies in its ability to handle combined loads—significant radial and unidirectional axial loads—simultaneously, making it ideal for high-speed spindles and precision machinery where minimal deflection is critical. Manufactured to a P4A tolerance class, it ensures superior running accuracy for enhanced performance.
S71914 ACE/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
- S7: Indicates a series of high-precision bearings.
- 19: Denotes a bore diameter of 70 mm (19 x 5 = 95mm, specific to this series).
- 14: Represents the outside diameter and width series.
- ACE: Signifies a 25° contact angle and specific internal design optimizations.
- P4A: Identifies the tolerance class, specifying very tight dimensional and running accuracy limits.
- DT: Stands for Duplex Tandem, indicating a preloaded set of two bearings arranged to handle axial loads in the same direction.
S71914 ACE/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The duplex tandem arrangement and preload create an exceptionally stiff bearing system, effectively resisting operational forces and minimizing shaft deflection under combined loads.
Precision Performance: The P4A tolerance class guarantees tight control over bore, outside diameter, and width dimensions, resulting in superior running accuracy and consistent performance.
Optimized for Speed: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 28,000 rpm. The standard grease lubrication is suitable for this operational range.
Durable Construction: Components made from chrome steel provide high hardness and wear resistance, ensuring long service life in precision applications.
