High-Precision Deep Groove Ball Bearing 6917 by MTZC

Ultra-Thin Wall Design
– Engineered with a slim 18mm cross-section for space-saving applications without compromising load capacity.
Premium Material & Durability
– Forged from high-carbon chromium steel (GCr15), heat-treated for exceptional hardness (HRC 60-64) and extended service life.
Versatile Sealing Options
– Choose between 2RS (rubber seals) for dust/water resistance or ZZ (metal shields) for high-speed operations (up to 8,000 rpm).
Precision-Ground Raceways
– Mirror-polished grooves reduce friction by 20%, ensuring smooth rotation in industrial machinery, automotive parts, and conveyor systems.
Global Standard Sizing
– Exact 85x120x18mm dimensions (ISO 15:2017 compliant) for seamless replacement in electric motors, pumps, and agricultural equipment.
Bulk Wholesale Advantage
– Direct factory pricing for orders over 100 units, backed by 12-month warranty against manufacturing defects.
Cross-Industry Utility
– Ideal for CNC spindles, robotics, and HVAC systems where low-noise, high-tolerance bearings are critical.
Certified Quality
– Rigorously tested under ANSI/ABMA Std 9-1990 for radial/axial load performance (static: 38 kN, dynamic: 62 kN).
