Finding a reliable deep groove ball bearing that fits your equipment specs can be frustrating. Many buyers face downtime due to mismatched dimensions, early wear from poor material quality, or limited brand options that force multi-supplier comparisons. When you need a bearing that meets international standards and performs consistently, the right choice matters.
The Timken NSK 61901 deep groove ball bearing addresses these challenges with precision manufacturing and versatile design. Built to ISO 9001 standards, it features bearing steel construction that ensures durability, while supporting both grease and oil lubrication for adaptability across operating conditions. Whether used in automation equipment conveyors or automotive gearboxes, this bearing delivers the reliability you need to minimize maintenance interruptions.
Designed as a radial bearing with a 0° contact angle, this single-row, unseparated unit excels in applications where radial loads are primary. Its non-aligning design works best in systems with minimal shaft misalignment, making it ideal for precision machinery and rotating components that require stable, low-friction operation. Available in multiple precision ratings (P0 to P4) and vibration classes (Z1V1 to Z3V3), it can be tailored to match your equipment’s performance requirements.
The 25x47x12 mm dimensions ensure compatibility with common industrial setups, while the choice of seal types (Zz, 2RS, Open) allows customization for different environmental conditions—from dusty manufacturing floors to clean automotive assembly lines. The use of high-quality bearing steel provides excellent surface hardness and wear resistance, directly contributing to longer service life. Precision ratings like P5 and P4 reduce vibration and noise, critical for sensitive equipment where operational smoothness is essential.
Selecting a substandard deep groove ball bearing may save upfront costs, but frequent replacements, unplanned downtime, and potential damage to adjacent components quickly erase those savings. The Timken NSK 61901’s robust construction and adherence to strict quality standards minimize these risks. By following ISO 281 fatigue life calculations, this bearing is engineered to perform under rated loads for extended periods, reducing the total cost of ownership over time.
Our manufacturing process follows ISO 9001 guidelines, with rigorous testing at every stage—from raw material inspection to final dimensional and hardness checks. Each bearing comes with a warranty against manufacturing defects, ensuring peace of mind. With access to a wide range of brands—including Timken, NSK, and our own BDL—we can source or supply the exact model you need, whether it’s a standard part or a custom solution.
Whether you need a single unit or bulk quantities, we can provide competitive pricing and fast delivery. Share your exact requirements—model, seal type, precision class, and quantity—and our team will confirm availability and lead time. The sooner you order, the sooner you can get your equipment back to peak performance.
Q: Do you supply other bearing brands or models besides Timken and NSK?
A: Yes, we support procurement of all major international brands (SKF, NTN, Koyo, NACHI, IKO, FAG, etc.) and domestic Chinese brands, as well as custom specifications.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (inner diameter x outer diameter x width), and our technical team will verify compatibility with the 6302 specification.
Q: What is your warranty policy for bearings?
A: We offer a warranty against manufacturing defects. Specific terms are detailed in our sales contract, with replacement or refund options for verified issues.
Q: What is the minimum order quantity for this bearing?
A: We accept low minimum order quantities, including single-unit purchases, to support both maintenance needs and production runs.
Q: How long does shipping take, and what methods are available?
A: In-stock items ship within 1-3 business days. Shipping options include express courier (3-5 days), air freight (5-7 days), or sea freight (3-6 weeks), depending on your location and urgency.
Q: Can you provide OEM or ODM services for custom bearings?
A: Yes, we support OEM/ODM customization based on customer-provided drawings, specifications, or sample requirements.
