S7005 CE/DBAVQ126 Bearing Product Overview & Core Advantages
The S7005 CE/DBAVQ126 is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This back-to-back (DB) matched set features an extra light preload (Class A) and P4A super-precision tolerance, making it ideal for high-speed spindles and other precision machinery. Its duplex configuration enables it to support combined loads (radial and axial) simultaneously from both directions, providing superior operational stability and rotational accuracy.
S7005 CE/DBAVQ126 Bearing Model Code Explained, Specifications & Naming Convention
| S7005 | Basic bearing series and size designation (25mm bore, 47mm OD) |
| CE | Contact angle of 15° |
| DB | Duplex Back-to-Back arrangement |
| AVQ126 | Specific internal design code for optimized performance |
S7005 CE/DBAVQ126 Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The back-to-back duplex arrangement creates a rigid bearing system that effectively resists moment loads, maintaining shaft positioning accuracy under combined loads. Manufactured to P4A super-precision tolerance standards, it ensures minimal runout and vibration.
Optimized High-Speed Performance: The phenolic resin cage provides excellent dimensional stability with low friction at high rotational speeds, contributing to the bearing's limiting speed of 83,000 rpm. The 15° contact angle balances axial and radial load capacity for high-speed applications.
Superior Load Capacity: With a dynamic load rating of 3038 lbf and static load rating of 1868 lbf, this bearing delivers reliable performance under significant operational stresses. The chrome steel construction of both rings and balls ensures durability and long service life.
Sealed & Pre-lubricated: The sealed design with factory-applied grease lubrication protects against contamination and provides maintenance-free operation within the specified temperature range of -30°C to 110°C.
