S7024 CD/P4AQBCB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The quadruplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moment loads. With a radial dynamic load rating of 69,075 lbf and static load rating of 110,250 lbf, this bearing delivers exceptional load-carrying capacity.
Precision Performance: Manufactured to P4A tolerance class standards, the bearing ensures minimal runout and vibration for high-precision applications. The 15° contact angle provides optimal balance between radial and axial load capacity.
High-Speed Capability: Featuring a phenolic cage and optimized internal geometry, the bearing achieves a limiting speed of 10,000 rpm, making it suitable for high-speed spindle applications.
Maintenance-Free Operation: The sealed design and factory-applied grease lubrication provide long-term, maintenance-free operation within the specified temperature range of -30°C to 110°C.
