Prevent Equipment Downtime with Reliable 61902 Series Deep Groove Ball Bearings
Nothing disrupts production like unexpected bearing failure. When low-quality bearings fail prematurely, you face costly downtime, missed deadlines, and expensive repairs. Sourcing genuine bearings with consistent quality and flexible order options can be a challenge, especially when dealing with multiple suppliers for different industrial needs.
High Precision 61902 Series Bearings for Critical Machinery
Our 61902NR, 61902-ZN, and 61902-ZNR deep groove ball bearings are engineered to solve these pain points. With a precision range from P0 to P4 and noise grades up to Z4, these bearings deliver stable performance in industrial machinery applications. We support flexible ordering with 1 piece MOQ for standard bearings, ensuring you get the exact quantity you need without excess inventory. Whether for CNC machine spindles or conveyor systems, these 15x28x7mm bearings provide reliable rotation you can depend on.
Optimized Performance in Demanding Industrial Conditions
The 61902 series excels in high-speed rotational applications, supporting radial loads with minimal friction. The single-row design and 0° contact angle make these bearings ideal for machinery requiring precise alignment and smooth operation. Constructed from high-grade bearing steel, they withstand continuous use in temperatures ranging from -30°C to 120°C, making them suitable for both indoor industrial environments and outdoor equipment like agricultural machinery and new energy systems.
Key Technical Features That Matter
Precision is critical in industrial bearings, and our 61902 series delivers. The 15mm bore diameter, 28mm outer diameter, and 7mm width ensure accurate fitting in standard equipment housings. The radial load capacity is optimized for industrial machinery, providing long service life even under continuous operation. Seal variants (NR, ZN, ZNR) offer protection against contaminants, extending bearing life by preventing dust and moisture ingress—essential for machines operating in factory settings with airborne particles.
Why Genuine Bearings Reduce Total Cost of Ownership
Choosing genuine deep groove ball bearings over counterfeit products directly impacts your bottom line. Fake bearings often fail within months, leading to unplanned downtime that can cost thousands in lost production. Our bearings meet ISO, ABMA, and DIN international standards, ensuring consistent performance and reliability. With a 12-month warranty, you’re protected against manufacturing defects, and our professional technical team provides support to maximize bearing life—ultimately lowering your total cost of ownership through reduced maintenance and longer service intervals.
