Product Description

HK0709/BK0709 High Precision Needle Roller Bearings with Cage

                                                          Application

Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being
supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated
by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and
roller followers.

Q4 – How to customize bearing(non-standard) from your company?

 A -We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.

Q5 –   What should I care before installation?

 A   – Normally, the preservative with which new bearings are coated before leaving the factory does not need to be

        removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible

        with the preservative, it is necessary to wash and carefully dry the bearing.

      -Bearings should be installed in a dry, dust-free room away from metal working or other machines producing

        swarf and dust.

Q6 – How to stock and maintenance my bearings right? 

 A   – Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;

      -Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity

       or sudden and severe temperature changes that may result in condensation forming;

      -Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.

Maintenance and Lubrication Requirements for Cup Bearings

Cup bearings, like other types of bearings, require proper maintenance and lubrication to ensure their longevity and reliable performance. Here are the key considerations:

1. Regular Inspection: Periodically inspect cup bearings for signs of wear, damage, or misalignment. This visual inspection can help identify issues early.

2. Lubrication: Most cup bearings require lubrication to reduce friction and dissipate heat. The type of lubrication and frequency of re-lubrication depend on the bearing’s design and application. Consult the manufacturer’s recommendations for specific guidelines.

3. Contamination Control: Preventing contaminants like dirt, dust, and moisture from entering the bearing is crucial. Seals and shields help protect cup bearings from contaminants and should be regularly inspected for damage.

4. Re-greasing: In applications that require lubrication, re-greasing should be performed at regular intervals to maintain the proper lubrication film. Over-greasing can lead to overheating, while under-greasing can cause premature wear.

5. Correct Installation: Proper installation is essential to ensure cup bearings operate as intended. Follow the manufacturer’s installation guidelines, including torque specifications for locking nuts.

6. Temperature Management: Be aware of operating temperature limits. High temperatures can degrade lubricants, while low temperatures can affect bearing performance. Choose the appropriate lubricant for the expected temperature range.

7. Relubrication Holes: Some cup bearings have relubrication holes or grooves for easy maintenance. Make use of these features if available.

8. Handling and Storage: Store cup bearings in a clean, dry environment. Handle them with care to avoid damage to the bearing surfaces or seals.

Proper maintenance and lubrication practices are essential to maximize the service life and performance of cup bearings in various industrial and mechanical applications.

Enhancing Efficiency and Functionality with Cup Bearings

Cup bearings provide several advantages that enhance the efficiency and functionality of mechanical systems:

1. Reduced Friction: Cup bearings are designed to reduce friction between moving parts, which results in less energy loss and increased mechanical efficiency. This reduction in friction leads to improved performance and energy savings.

2. Load Support: Cup bearings offer excellent load-carrying capabilities, making them suitable for applications where heavy loads need to be supported. This ensures the stability and reliability of mechanical systems under varying loads.

3. Misalignment Compensation: Cup bearings can accommodate misalignment to some extent, allowing mechanical systems to operate smoothly even when components are not perfectly aligned. This feature minimizes wear and tear and prolongs the lifespan of the machinery.

4. Durability: Cup bearings are known for their durability, which contributes to the longevity of mechanical systems. They can withstand heavy loads, shock loads, and harsh environmental conditions without compromising their performance.

5. Precision: In applications where precision is crucial, such as manufacturing and automation, cup bearings provide the necessary stability and accuracy. This precision ensures that machinery operates as intended, leading to high-quality output.

6. Versatility: Cup bearings are versatile and can be customized to meet the specific needs of different mechanical systems. This adaptability allows them to be used in a wide range of applications.

7. Reduced Maintenance: The durability and reliability of cup bearings result in lower maintenance requirements. Reduced maintenance leads to increased uptime and cost savings for businesses relying on mechanical systems.

Overall, cup bearings are instrumental in enhancing the overall efficiency, functionality, and performance of mechanical systems across various industries.

Components of a Cup Bearing Assembly and Their Roles

A cup bearing assembly consists of several components, each with a specific role in its operation:

1. Cup (Outer Ring): The cup, often referred to as the outer ring, is a hardened steel component with a precisely machined raceway. It serves as the outer race and provides structural support for the bearing. The cup’s role is to maintain the proper distance and alignment between the rollers.

2. Cone (Inner Ring): The cone, or inner ring, is another hardened steel component. It has a matching raceway that fits with the cup’s raceway. The cone serves as the inner race and contains the rolling elements. Its role is to maintain proper alignment and spacing of the rolling elements.

3. Tapered Rollers: Tapered rollers are the rolling elements that transmit the loads and facilitate smooth rotation. They are arranged between the cup and cone and are designed with a tapered shape to distribute loads evenly along the raceways, reducing the risk of edge loading and premature wear.

4. Cage (Retainer): In some cup bearing assemblies, a cage or retainer is used to maintain the spacing and orientation of the rollers. The cage ensures that the rollers do not come into direct contact with each other, reducing friction and wear while promoting smooth rolling.

5. Lubrication: Proper lubrication is crucial for the efficient operation of cup bearings. Lubricant, often grease or oil, reduces friction, dissipates heat, and minimizes wear. It also helps prevent corrosion and extends the bearing’s service life.

6. Seals and Shields: In many cup bearing applications, seals and shields are employed to protect the bearing’s internal components from contaminants and moisture. Seals create a barrier to prevent the entry of foreign particles, while shields provide limited protection while allowing some ventilation.

7. Bearing Housing: The bearing assembly is often mounted within a bearing housing, which secures it in place and aligns it with the rotating shaft. The housing provides support and ensures proper axial and radial alignment of the cup bearing.

All these components work together to facilitate the smooth and reliable operation of a cup bearing, handling various loads while minimizing friction and wear, thereby extending the bearing’s lifespan and contributing to the efficiency of the machinery it serves.
