The 6306 DDU deep groove ball bearing (standard dimensions: 30mm ID × 72mm OD × 19mm Width) is a versatile general-purpose bearing designed for diverse industrial transmission scenarios. Equipped with double-sided contact rubber seals (DDU), it provides excellent dustproof and waterproof performance, effectively isolating external contaminants while retaining lubriing grease. Crafted from premium GCr15 bearing steel, it undergoes precision heat treatment and raceway superfinishing, delivering high radial load capacity, low friction, and stable long-term operation. Its deep groove structure enables it to bear moderate axial loads in both directions, making it suitable for a wide range of general mechanical equipment. Customizable lubriion types and seal structures are supported to meet personalized working condition requirements.
