Customer Questions & Answers

  • Question: What is an NTN Bearing 6304LU used for?

    Answer: The NTN Bearing 6304LU is primarily used in various applications requiring rotational motion and support, such as motors, conveyors, and industrial machinery. It is designed with a single row deep groove configuration, allowing it to accommodate radial loads, axial loads, or a combination of both. This versatility makes it ideal for automotive, agricultural, and general industrial sectors where reliable performance and durability are essential.
  • Question: What are the dimensions of the NTN Bearing 6304LU?

    Answer: The NTN Bearing 6304LU features a bore diameter of 20 mm, an outer diameter of 52 mm, and a width of 15 mm. These specific dimensions make it suitable for a wide range of applications where space constraints and load capacity are critical factors. The compact size combined with its robust design allows it to perform effectively in both light and heavy-duty scenarios.
  • Question: What does 'LU' mean in NTN Bearing 6304LU?

    Answer: 'LU' in NTN Bearing 6304LU designates that the bearing is sealed on one side to protect against contamination and retain lubricant. This feature enhances the bearing's lifespan and reliability, making it ideal for environments exposed to dust, dirt, or splashes. Sealed bearings like the 6304LU are often used in applications where maintenance access is limited or infrequent.
  • Question: How does the steel cage of the NTN Bearing 6304LU benefit its performance?

    Answer: The steel cage in the NTN Bearing 6304LU provides superior strength and durability, helping to maintain the proper spacing between the balls within the bearing. This enhances its performance by reducing friction, increasing load-carrying capacity, and extending operational life. The robust cage design ensures consistent operation under varying load conditions, making it an ideal choice for demanding applications.
  • Question: What kind of clearance does the NTN Bearing 6304LU have?

    Answer: The NTN Bearing 6304LU is produced with normal clearance, which allows for slight movement between the rolling elements and the inner/outer rings. This standard clearance is advantageous in most operating conditions, as it accommodates thermal expansion and ensures optimal performance. For applications with higher temperature fluctuations or varying loads, understanding clearance is crucial for selecting the right bearing type.
  • Question: Can the NTN Bearing 6304LU be used in high-speed applications?

    Answer: Yes, the NTN Bearing 6304LU can be effectively used in high-speed applications due to its deep groove design. This configuration reduces friction and enables smooth rotation. The high-speed capability makes it suitable for uses in electric motors, pumps, or even robotics where precision and reliability are paramount. However, proper lubrication and maintenance are essential to achieve optimal performance in such scenarios.
  • Question: What lubrication should be used for the NTN Bearing 6304LU?

    Answer: The NTN Bearing 6304LU requires a suitable lubricant, typically a high-quality grease or oil, depending on the application's temperature and speed needs. Using the correct lubrication is crucial to minimize wear, reduce heat generation, and prolong the bearing's life. Regular checks and replenishing the lubricant can significantly improve performance, especially in continuous-duty environments.
  • Question: Is the NTN Bearing 6304LU suitable for automotive applications?

    Answer: Absolutely, the NTN Bearing 6304LU is well-suited for automotive applications, including wheels, transmissions, and engines. Its robust design and reliable performance make it capable of enduring the demanding conditions often found in vehicles. This bearing helps to ensure smooth operation, efficient power transfer, and reduced friction in essential automotive components.
  • Question: What industries commonly use the NTN Bearing 6304LU?

    Answer: The NTN Bearing 6304LU is utilized across various industries, including manufacturing, automotive, agricultural machinery, and robotics. Its versatility and reliable performance make it a prime choice for any application requiring efficient motion and load management. Whether in conveyor systems, motor assemblies, or general machinery, this bearing consistently meets industry standards for quality and efficiency.
