Many maintenance managers face the same problem: bearings that wear out prematurely, causing unexpected downtime and repair costs. When a radial bearing fails due to poor precision or material quality, it can damage costly equipment and disrupt production schedules. Sourcing the right replacement—especially across different brands and standards—often means spending hours comparing specifications and waiting for quotes from multiple suppliers.
The Timken 30314 Tapered Roller Bearing addresses these challenges with its high-quality bearing steel construction and precision manufacturing. As a professional bearing supplier with ISO 9001 certified production processes, we ensure each unit meets strict dimensional and hardness standards. Whether you need this exact model or a cross-reference to another brand, our extensive inventory includes options from SKF, NSK, NTN, and other leading manufacturers, allowing you to source all your bearing needs from a single partner.
Designed as a single-row radial bearing with a 0° contact angle, this unit excels in applications where radial loads are the primary force. Its non-aligning design ensures stability in fixed-shaft assemblies, while the unseparated structure simplifies installation and maintenance. With vibration ratings from Z1V1 to Z3V3, it operates smoothly even in high-speed machinery, making it suitable for everything from industrial gearboxes to automotive drivetrains.
The 17mm bore diameter, 47mm outside diameter, and 14mm width (17*47*14mm) provide a compact footprint without compromising load capacity. Precision ratings from P0 to P4 mean you can select the exact tolerance level needed—P0 for general industrial use, P5 or P4 for high-precision applications like CNC machines. The bearing steel material offers excellent wear resistance, while the option for grease or oil lubrication allows customization based on operating conditions. For applications requiring contamination protection, choose the Zz (metal shield) or 2RS (rubber seal) variants to extend service life.
Investing in a quality tapered roller bearing like the Timken 30314 reduces long-term costs by minimizing downtime and replacement frequency. Inferior bearings often fail early due to substandard material hardness or imprecise dimensions, leading to secondary damage to shafts and housings. By contrast, this bearing’s adherence to international standards ensures consistent performance, and its compatibility with major brand specifications means you can replace worn units without redesigning equipment. When factoring in reduced maintenance hours and fewer production interruptions, the initial investment in a reliable bearing delivers significant returns.
Our commitment to quality starts with raw material inspection and continues through every stage of production. Each bearing undergoes rigorous testing for dimensions, surface hardness, and vibration levels to ensure compliance with industry standards. We stand behind our products with a manufacturer’s warranty, covering any defects in materials or workmanship. With a diverse range of brands—including our own BDL line and international names—we can fulfill orders for both standard and custom (OEM/ODM) requirements, all with low minimum order quantities to suit your needs.
Whether you need this specific model or a cross-reference to another brand, we can provide competitive pricing and fast delivery. Simply share the bearing model, dimensions, and quantity, and our technical team will confirm compatibility with your application. The sooner you order, the sooner we can ship—minimizing your equipment downtime and keeping your operations running smoothly.
