| P4A | High precision tolerance class |
| DT | Duplex Tandem arrangement for increased axial load capacity in one direction |
S7012 ACE/P4ADT Bearing Structural Features & Performance Benefits
Enhanced Rigidity & Load Capacity: The duplex tandem arrangement of two bearings creates an exceptionally rigid system capable of withstanding heavy combined loads. The 25° contact angle is optimized for handling substantial axial loads in one direction while maintaining excellent radial load capacity.
High-Speed Performance: The phenolic resin cage ensures stable operation at high rotational speeds, contributing to the bearing's impressive limiting speed of 31,000 rpm. This makes it suitable for high-speed applications where minimal vibration is critical.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing delivers exceptional running accuracy and predictable performance in precision machinery.
Sealed & Lubricated Design: The sealed construction with factory-applied grease lubrication provides long-term protection against contamination and ensures reliable operation within the specified temperature range of -30°C to 110°C.
