Technical Entity Analysis: Angular Contact Steel Ball Bearing 7012AC-2RZ DBB
Entity: Angular Contact Steel Ball Bearing 7012AC-2RZ DBB | Brand: TriQuench India | Model / SKU: 7012AC-2RZ DBB P4 | Classification: Spindle Bearing > Angular Contact Steel Ball Bearing
The Angular Contact Steel Ball Bearing 7012AC-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 25-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 a limiting speed of 18,500 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.
Engineering Features: Optimized internal contact geometry engineered for high-speed 18,500 r/min operations; Precision-ground steel ball elements ensure minimal frictional friction and heat generation; Premium double rubber seals (2RZ) provide contamination protection against fine dust and coolant; Matched back-to-back structural configuration maximizes radial stability and axial load tracking; High structural rigidity preserves bearing life and reduces expensive spindle downtime; Perfect replacement choice for heavy-duty CNC routing and industrial milling spindles
Compatible Machine Applications: High-Speed High-Frequency CNC Router Spindle Shaft Support Assembly; Vertical Machining Center (VMC) and Milling Machine Axial Guidance Systems; Heavy-Duty Industrial AC Spindle Motor Rotating Frameworks; Precision Automotive, Aerospace, and Gantry Motion Control Rigs; High-RPM Automated Indexing Turntables and Rotary Mechanism Mounts
