Product Description
NK/BK Series Drawn Cup Needle Roller Bearings Without Inner Ring
Application
Needle Roller Bearings have a high load carrying capacity and can operate at high speeds. They have
slim design and are suited where radial space is limited. They are available with or without an inner ring.
Needle roller bearings without inner ring offer technically the best bearing arrangement solution if the
shaft raceway is hardened and ground. This allows for the use of larger shafts and design alternatives.

– Spherical Plain Bearing, Rod End, Ball Joint, Wheel Hub, Tapered Roller Bearing
Q3 – Process of our production
A – Heat Treatment – Grinding – Parts Inspection – Assembly – Final Inspection – Packing
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.

Contribution of Cup Bearings to Smooth Operation and Reduced Friction
Cup bearings play a crucial role in ensuring the smooth operation of machinery while minimizing friction. Their design and functions contribute to this in several ways:
- Reduced Friction: Cup bearings are designed to minimize friction between moving parts. Their rolling elements, such as balls or rollers, reduce contact surfaces and enable smooth, low-friction movement. This reduces energy consumption and heat generation in the machinery.
- Load Distribution: Cup bearings distribute loads evenly across their rolling elements. This even load distribution prevents excessive stress on specific points and ensures that the machinery operates smoothly without experiencing undue wear or damage.
- Alignment Tolerance: Cup bearings can accommodate misalignment to some degree. This ability to handle minor misalignments ensures that even in less-than-ideal conditions, the machinery can continue to operate smoothly and efficiently.
- Minimized Wear: The rolling elements and races of cup bearings are often made from materials with excellent wear resistance. This minimizes wear and extends the service life of the bearing and the machinery in which it is used.
- Reduced Heat Generation: The low friction and efficient load distribution of cup bearings result in reduced heat generation during operation. This is particularly important in high-speed machinery where excessive heat can lead to premature wear and reduced efficiency.
Overall, cup bearings contribute to the efficient and smooth operation of machinery by reducing friction, ensuring even load distribution, and providing tolerance for misalignment. These factors are essential for minimizing wear, extending the lifespan of the machinery, and maintaining high performance.
Contribution of Cup Bearings to Machinery Durability and Reliability
Cup bearings play a significant role in enhancing the durability and reliability of machinery by offering several key benefits:
1. Load Distribution: Cup bearings distribute axial and radial loads evenly, preventing localized wear and reducing the risk of premature component failure.
2. Reduced Friction: These bearings minimize friction between moving parts, leading to smoother operation, less heat generation, and increased energy efficiency.
3. Precision: Cup bearings provide precise control over the positioning of machine components, ensuring accurate alignment and reduced wear over time.
4. Longevity: Properly maintained cup bearings have a longer service life, resulting in less frequent replacements and reduced downtime.
5. Low Maintenance: Self-lubricating cup bearings require minimal maintenance, reducing operational costs and extending the intervals between servicing.
6. Versatility: Cup bearings are adaptable and available in various sizes and designs to suit different applications, making them versatile components in machinery.
7. Load-Carrying Capacity: These bearings can handle substantial loads, making them suitable for heavy-duty applications where durability is crucial.
8. Contaminant Protection: Proper sealing options in cup bearings shield internal components from contaminants, ensuring a cleaner and more reliable operation.
9. Shock and Vibration Resistance: Cup bearings are designed to withstand shock loads and vibrations, maintaining stability in machinery subjected to varying operating conditions.
10. Consistency: The manufacturing precision of cup bearings ensures consistent performance, reducing variability in machinery operation.
Overall, cup bearings contribute to the longevity, reliability, and efficient operation of machinery across a wide range of industries, making them indispensable components in mechanical systems.
Types of Cup Bearings for Various Applications
Cup bearings, also known as tapered roller bearings, come in several types to suit different applications. These variations are designed to accommodate specific load capacities, axial and radial forces, and operational conditions. Here are some common types:
1. Single-Row Tapered Roller Bearings: These cup bearings consist of a single row of tapered rollers between the inner and outer rings. They are suitable for applications with moderate radial and axial loads, such as in wheel hubs, transmissions, and differentials in automobiles.
2. Double-Row Tapered Roller Bearings: Double-row cup bearings have two rows of tapered rollers and can handle higher radial and axial loads compared to single-row bearings. They are often used in heavy machinery and gearboxes that require increased load-carrying capacity.
3. Four-Row Tapered Roller Bearings: Four-row cup bearings are designed for extremely heavy radial and axial loads. They are common in rolling mills, where they support the massive rolls used for metal shaping and processing. These bearings can withstand high forces and offer exceptional load-carrying capabilities.
4. Precision Tapered Roller Bearings: Precision cup bearings are manufactured to very tight tolerances, ensuring high accuracy and smooth operation. They are used in applications where precision, such as in machine tool spindles and aerospace components, is critical.
5. Matched Tapered Roller Bearings: Matched cup bearings consist of two tapered roller bearings with pre-set clearances and axial play. They are often used in pairs to support axial thrust in both directions. This type is common in machine tool spindles and automotive wheel bearings.
6. Custom Tapered Roller Bearings: Manufacturers can produce custom cup bearings to meet specific application requirements. These can include variations in size, load capacity, and other design parameters tailored to a particular application.
The choice of cup bearing type depends on the specific demands of the application, load requirements, and operating conditions. Proper selection ensures optimal performance and longevity in various industries, from automotive to industrial machinery.
