The Angular Contact Steel Ball Bearing 7000C-2RZ DBB is an elite mechanical component specifically engineered for high-speed industrial applications demanding absolute concentricity and rigorous axial load tracking. Designed primarily for integration into high-performance CNC spindle shafts, high-frequency milling routers, and heavy-duty electric motors, this bearing features an optimized internal 15-degree contact angle profile. This geometric configuration enables it to support heavy simultaneous radial and axial forces smoothly. Built from premium-grade carbon-chromium bearing steel, it delivers high torsional rigidity and structural endurance, keeping micro-runout to negligible tolerances even at an extreme limiting speed of 88,900 r/min. To maintain operating conditions in harsh woodworking or metal-milling environments, the unit is fitted with light-contact double rubber seals (2RZ). These seals provide reliable retention of synthetic speed grease while creating a durable barrier against ultra-fine dust, metallic chips, and liquid coolant mist. The DBB configuration represents a matched back-to-back arrangement with pre-loaded balancing, which absorbs high-frequency harmonics, minimizes thermal expansion, and ensures quiet operational cycles under full manufacturing workloads.
Technical Core: Rated for industrial-grade output, maximum rotational velocity of high-performance, operating voltage of 220V/380V, with Water/Air Cooled thermal stabilization.
