Finding the right deep groove ball bearing often means sifting through endless models, only to face issues like premature wear from poor material quality or compatibility problems with existing equipment. Many buyers waste time coordinating with multiple suppliers for different brands, while others discover too late that a bearing’s precision class doesn’t match their application’s requirements.
Our 61902-Z/2Z deep groove ball bearing addresses these challenges with ISO 9001-certified manufacturing processes and dimensions compatible with major international standards. Available in Zz, 2RS, or open configurations, it suits diverse industrial needs—from high-speed automation equipment to compact automotive components. With现货库存 (ready stock) and support for low minimum orders, we eliminate the delays of traditional procurement.
Designed as a single-row radial bearing with a 0° contact angle, this 17x26x5 mm bearing excels in applications with primarily radial loads and moderate axial loads. Its non-aligning design performs best in rigidly mounted systems where shaft misalignment is minimal, such as small electric motors or precision conveyor mechanisms. The Z1V1 to Z3V3 vibration classes allow selection based on noise and smoothness requirements, ensuring compatibility with sensitive equipment.
The bearing’s performance stems from critical design features: Bearing steel construction provides the hardness needed to resist wear under cyclic loads, while precision ratings from P0 (standard) to P4 (high precision) accommodate everything from general industrial use to precision machinery. Choose between Zz (metal shielded) or 2RS (rubber sealed) variants—Zz offers better high-temperature tolerance, while 2RS provides superior contamination protection in dusty environments. Lubrication flexibility (grease or oil) allows adaptation to operating speeds and temperature ranges, optimizing friction reduction and longevity.
Investing in a quality deep groove ball bearing like the 61902-Z/2Z reduces long-term costs by minimizing downtime. Inferior bearings often fail early due to substandard material hardness or imprecise dimensions, leading to unplanned maintenance and production losses. Our bearings undergo rigorous testing—including dimensional checks, hardness verification, and surface finish inspection—to ensure compliance with industry standards. By matching the right precision class (P0-P4) and seal type to your application, you avoid over-specifying (and overpaying) or under-specifying (and facing premature failure).
Our manufacturing and testing processes adhere to ISO 9001 standards, with strict incoming material inspections and comprehensive final product testing for dimensions, hardness, and surface treatment. We stand behind our bearings with a warranty against manufacturing defects, ensuring you receive reliable components. Whether you need our自有 brand BDL or require a specific international brand, our extensive supply chain allows us to source and deliver the exact bearing you need, with flexible OEM/ODM options for custom requirements.
Whether you need the 61902-Z/2Z model or another deep groove ball bearing, provide your required specifications—including model number, seal type, precision class, and quantity—and our team will promptly send a detailed quote. We handle all major brands and can source hard-to-find models, ensuring you get the right bearing without the hassle of multiple suppliers.
Q: Do you supply bearings from other brands besides BDL?
A: Yes, we support procurement of all major international and domestic brands. Specify your required brand, and we will source accordingly.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment’s required dimensions (bore diameter, outer diameter, width) or existing bearing model number, and our technical team will verify compatibility.
Q: What is your warranty policy for bearings?
A: We offer a warranty against manufacturing defects. Specific terms are detailed in each order’s contract, covering replacement or refund for verified quality issues.
Q: What is the minimum order quantity for this bearing?
A: We accept low minimum orders, including single-unit purchases for emergency repairs, with volume discounts available for larger quantities.
Q: How long does shipping take?
A:现货 (In-stock) bearings ship within 1-2 business days. Shipping time depends on method: express courier (3-5 days), air freight (5-7 days), or sea freight (3-4 weeks).
Q: Can you produce custom bearings to specific designs?
A: Yes, we offer OEM/ODM services for custom bearing designs. Provide your technical drawings or specifications, and we will evaluate production feasibility.
