Many maintenance teams face the same frustrating cycle: bearings that fail prematurely due to poor precision, seals that can’t handle operating conditions, or spending hours sourcing specific models across multiple suppliers. When a 6302 or 6303 bearing gives out unexpectedly, it halts production, increases downtime, and creates unnecessary costs.
Our deep groove ball bearings address these challenges with ISO 9001-certified manufacturing processes and interchangeable dimensions with major international standards. Available in both 6302 (15x42x13mm) and 6303 variants with Zz, 2RS, or open designs, these bearings support radial loads in everything from electric motors to conveyor systems. With现货库存 (ready stock) and low minimum order quantities, we eliminate the delays of traditional sourcing.
Designed as non-aligning radial bearings with a 0° contact angle, this series excels in applications with moderate rotational speeds (up to typical industrial motor RPM ranges) and steady radial loads. The single-row design and unseparated construction ensure simplicity in installation, while options for Z1V1 to Z3V3 vibration levels let you match bearing performance to your equipment’s sensitivity requirements—critical for precision automation or low-noise environments.
The bearing steel construction provides the hardness needed to resist wear under continuous operation, with precision ratings from P0 (standard) up to P2 (high precision) to meet tight tolerance requirements. For applications where maintenance access is limited, the 2RS sealed variant retains grease longer than open designs, reducing lubrication frequency. The choice between grease or oil lubrication allows adaptation to temperature variations and load conditions, ensuring optimal friction management. When selecting a seal type, remember: Zz metal shields offer basic protection against contaminants, while 2RS rubber seals provide better moisture resistance in humid environments.
Opting for a precision-rated bearing might seem like a small detail, but it directly affects equipment uptime. A P5-rated bearing maintains tighter dimensional control than P0, reducing vibration-induced wear on adjacent components. Similarly, bearings with Z3V3 vibration等级 minimize noise and extend service life in high-speed applications. The hidden cost of inferior bearings—early failure, unplanned maintenance, and production loss—far outweighs the investment in quality components. Our bearings undergo rigorous dimensional and hardness testing to ensure they meet DIN, ISO, and ANSI standards, helping you avoid these avoidable expenses.
Every bearing in our inventory follows ISO 9001 quality protocols, from raw material inspection to final dimensional testing. We verify surface hardness, seal integrity, and precision tolerance for each batch, ensuring consistent performance. All bearings come with a manufacturer’s warranty covering material and manufacturing defects. As a full-range bearing supplier, we source both自有品牌 and international standard models, so you can specify the exact make or performance level your application requires. With production capacity exceeding 1,000,000 units annually, we maintain stable inventory for quick fulfillment.
Whether you need a specific seal type, precision等级, or quantity, we can provide a tailored quote. Simply share the model number (e.g., 6302-2Z), required specifications, and delivery location, and our team will confirm pricing and availability. We also accept custom OEM/ODM requests for non-standard configurations—just provide your technical drawings or performance criteria.
