• [Ultra-Thin Space-Saving Design] Model: 6809-ZZ (6809Z). Dimensions: 45mm (Inner) x 58mm (Outer) x 7mm (Width). Engineered for applications where space is limited and a large shaft diameter is required. Perfect for modern robotics and lightweight mechanical assemblies
• [Dual Metal Shields for Performance] Features double-sided metal shields (ZZ) that protect the high-speed synthetic grease from large particles and dust. Unlike rubber seals, the ZZ design offers minimal friction, allowing for higher limiting speeds and cooler operation
• [High-Grade GCr15 Chrome Steel] Constructed from premium high-carbon chrome steel for maximum durability and resistance to wear. Our 6809ZZ bearings are heat-treated to ensure high dimensional stability even under continuous industrial loads
• [ABEC-3 Precision & Low Noise] Manufactured to ABEC-3 precision standards with tight tolerances. Every bearing is factory-tested for Z2 noise levels and V2 vibration, ensuring ultra-smooth rotation and a quiet working environment
• [Versatile Industrial Applications] Widely used in electric motors, agricultural equipment, bicycle hubs, textile machinery, and printing presses. A reliable high-performance replacement part for both professional maintenance and DIY projects
