Many motorcycle maintenance teams face the frustration of sourcing bearings that match original specifications, only to receive parts with inconsistent dimensions or poor material quality. This often leads to premature wear, increased vibration, and costly downtime—especially critical in high-performance motorcycle applications where precision matters most.
Our NSK 31324, 31326, and 31328 Tapered Roller Bearings address these challenges with ISO 9001-certified production processes and strict quality control. As a professional bearing supplier with access to both international brands like NSK and domestic quality manufacturers, we ensure you get bearings that meet the exacting standards required for motorcycle drivetrains, where radial and axial load handling is essential.
These tapered roller bearings excel in applications with combined radial and thrust loads, making them ideal for motorcycle wheel hubs and transmission systems. Operating temperatures from ambient to typical engine heat ranges are well-managed by the bearing steel construction, while the open design allows for flexible lubrication with oil, grease, or dry methods depending on maintenance preferences.
The single-row cylindrical structure provides high radial load capacity, critical for supporting motorcycle wheel assemblies under dynamic riding conditions. Precision ratings from P0 to P2 ensure dimensional accuracy, reducing vibration and noise during operation. The separated design simplifies installation and maintenance, allowing for easy bearing replacement without disassembling the entire component. Surface hardness complies with industry standards, ensuring resistance to wear even under repeated load cycles.
Investing in quality tapered roller bearings reduces long-term costs by minimizing premature failures. Inferior bearings with substandard material hardness or imprecise dimensions often lead to increased friction, overheating, and damage to adjacent components. Our bearings, manufactured to strict tolerances, extend service intervals and reduce the need for frequent replacements—directly impacting your bottom line through lower maintenance expenses and less downtime.
Every bearing undergoes rigorous testing, including raw material inspection and成品尺寸、硬度及表面处理检测. We stand behind our products with a warranty against manufacturing defects, ensuring peace of mind for your operations. With extensive inventory across multiple brands, we can fulfill orders quickly, whether you need a single replacement bearing or bulk quantities for production.
Whether you need to replace existing bearings or source for new motorcycle builds, provide us with the model number, required quantity, and delivery location. Our team will promptly confirm availability and pricing, ensuring you get the right bearings when you need them.
Q: Do you supply other bearing brands or models beyond NSK?
A: Yes, we offer a full range of bearings from international brands including SKF, NTN, Koyo, NACHI, and Timken, as well as domestic quality brands. We can source any specified model or brand according to your requirements.
Q: How can I confirm if this bearing fits my motorcycle model?
A: Provide your motorcycle’s make, model, and year, or the original bearing dimensions (inner diameter, outer diameter, width), and our technical team will verify compatibility with the NSK 31324, 31326, or 31328 specifications.
Q: What is your warranty policy for these bearings?
A: We provide a warranty against manufacturing defects. Specific terms and duration are outlined in each order’s contract, ensuring coverage for material and workmanship issues.
Q: What is the minimum order quantity for these NSK tapered roller bearings?
A: We support low minimum order quantities, including single-unit purchases, making it easy to source both small maintenance batches and large production volumes.
Q: How quickly can you ship the bearings after ordering?
A: Stock items are shipped within 1-3 business days. For larger orders or special requirements, lead times will be confirmed at the time of quote.
Q: Do you offer OEM or ODM customization for bearings?
A: Yes, we support OEM and ODM services, including custom dimensions, materials, and packaging, based on your technical drawings or specifications.
