Motorcycle bearings face constant radial loads, varying temperatures, and exposure to debris. Choosing the wrong seal type or precision grade often leads to premature failure—costing time and money in replacements. Many buyers struggle to source multiple brands or confirm dimensional compatibility across different standards.
Our NSK 6201, 6202, and 6300 deep groove ball bearings address these challenges with interchangeable dimensions following international standards (DIN, ISO, JIS). Available with Zz, 2RS, or open seals, they suit diverse motorcycle models and operating conditions. Backed by ISO 9001-certified quality control, we ensure each bearing meets specified precision ratings (P0 to P2) for smooth operation in handlebar stems, wheel axles, and engine crankcases.
Designed as radial bearings with a 0° contact angle, these single-row bearings excel in applications where load is primarily directed perpendicular to the shaft. The 40x80x18 mm specification balances durability and weight (0.4 Kg), making it ideal for motorcycle components where space and weight are critical. Vibration grades Z1V1 to Z3V3 allow selection based on noise and smoothness requirements—from standard commuter bikes to high-performance models.
Bearing steel construction ensures high surface hardness and wear resistance, critical for withstanding the cyclic stresses of motorcycle operation. The unseparated design simplifies installation and maintenance, while lubrication options (grease or oil) provide flexibility for different operating temperatures. Precision ratings directly impact performance: P0 for general use, P5/P4 for higher speed applications, and P2 for specialized precision needs. Seals play a vital role too—2RS for dust and moisture protection in off-road conditions, Zz for high-temperature environments, and open designs for applications requiring frequent relubrication.
Choosing a low-quality bearing may save upfront costs but often leads to hidden expenses: early wear causing vibration, seal failure allowing contamination, or precision issues leading to uneven tire wear. ISO 281 load rating standards help predict service life, but accurate material selection and manufacturing control are equally important. Our bearings undergo rigorous testing—including dimensional checks, hardness verification, and surface treatment inspection—to minimize the risk of premature failure, reducing downtime and replacement costs over the long term.
All bearings are produced under ISO 9001-certified processes, with raw material inspection and finished product testing for dimensions, hardness, and surface quality. We offer a warranty against manufacturing defects, ensuring you receive bearings that meet specified performance standards. Our extensive network includes access to both international brands (such as NSK) and domestic alternatives, allowing us to fulfill orders for specific models or cross-reference replacements. With substantial inventory, we can support both small urgent orders and large-scale production requirements.
Whether you need NSK 6201, 6202, 6300, or other deep groove ball bearing models, provide your required specifications (model, dimensions, seal type, quantity) and destination. Our team will confirm availability, pricing, and delivery time—helping you secure the right bearings without unnecessary delays.
Q: Do you supply bearings from other brands besides NSK?
A: Yes, we support procurement across a wide range of international and domestic brands, including SKF, NTN, Koyo, NACHI, and more. Specify your preferred brand or model for a tailored quote.
Q: How can I confirm if this bearing fits my motorcycle model?
A: Provide your motorcycle’s make, model, year, and the specific application (e.g., front wheel, transmission), or share the original bearing’s dimensions (inner diameter x outer diameter x width). Our technical team can verify compatibility.
Q: What warranty is offered on these bearings?
A: We provide a warranty against manufacturing defects. The exact duration and terms are specified in each order’s contract, typically covering material and workmanship issues.
Q: What is the minimum order quantity for these motorcycle bearings?
A: We accept low minimum order quantities, starting from single units for emergency replacements up to bulk orders for production lines.
Q: How long does shipping take to [my location]?
A: Shipping time depends on the destination and chosen method. Express courier delivers in 3-5 days, air freight in 7-10 days, and sea shipping in 25-40 days. We’ll provide a precise estimate with your quote.
Q: Can you produce custom bearings with specific dimensions or features?
A: Yes, we offer OEM/ODM services for custom bearing requirements. Provide your technical drawings, material specifications, and performance criteria for a feasibility assessment and quote.
