NEEDLE BEARING
Needle bearings are a type of roller bearing featuring long, thin cylindrical rollers that provide exceptional load capacity relative to their small diameter. They are ideal for applications requiring compact size, high load capacity, and minimal cross-sectional height, making them widely used in automotive, industrial machinery, and aerospace applications.
Here’s a detailed look at the popular types and series of needle bearings available at New Jaydeep Bearing. This list includes diverse series, each designed to meet specific performance demands and suitable for various applications.
1. HK Series
Description: The HK series of needle roller bearings are drawn cup needle roller bearings with open ends. They have a compact design, which enables high load-bearing capacity while occupying minimal space.
Applications: Often used in automotive components, light industrial machines, and electric motors.
Example Sizes: HK0610, HK0612, HK3012.
2. NK Series
Description: These needle roller bearings have a heavy load capacity with a high level of stiffness and are commonly used in applications requiring a combination of radial load and compact design.
Applications: Suitable for gearboxes, transmissions, and differential systems.
Example Sizes: NK25/20, NK40/30.
3. BK Series
Description: The BK series is a variation of the HK series with closed ends, which helps to retain grease within the bearing, providing extended lubrication life.
Applications: Primarily used in applications where the shaft end is exposed and needs a sealing solution, like hydraulic pumps and compressors.
Example Sizes: BK1512, BK3016.
4. SCE and SCH Series
Description: SCE and SCH are needle roller bearings that come in inch sizes, designed for compact machinery needing high load capacity.
Applications: Typically used in applications in the United States where inch sizes are standard, like off-road vehicles and agricultural equipment.
Example Sizes: SCE66, SCH88.
5. NKI and HKI Series
Description: These are solid needle roller bearings with or without inner rings, allowing them to handle heavier loads and offering high stiffness in limited spaces.
Applications: Ideal for transmissions, camshaft journals, and construction equipment.
Example Sizes: NKI20/16, HKI20/16.
6. K Cage Series
Description: The K series features needle roller and cage assemblies that are particularly compact and can fit into small spaces with high load-carrying capacity.
Applications: Commonly found in automotive transmissions and industrial machinery with space constraints.
Example Sizes: K16X22X12, K35X40X17.
7. NA4900 and NA6900 Series
Description: These bearings are full-complement needle roller bearings with a solid outer ring and either a split or solid inner ring, supporting higher radial loads.
Applications: Used in gear pumps, hoist drums, and heavy-duty machines.
Example Sizes: NA4900, NA6900.
8. NKIS, NKIB, NKIA Series
Description: The NKIS series handles larger shafts, while the NKIB and NKIA series are used for applications needing both radial and axial loads. NKIA and NKIB can handle slight angular misalignment.
Applications: Ideal for high-load industrial machines, hoisting equipment, and automotive gearboxes.
Example Sizes: NKIS20, NKIB5901, NKIA5902.
9. JK Series
Description: The JK series includes needle roller bearings designed for high-speed and heavy-load applications.
Applications: Often found in automotive and machinery applications needing consistent, high-speed performance.
Example Sizes: JK0-60, JK0-40.
10. TA Series
Description: TA series needle bearings feature a full-complement design without an inner ring, providing high load capacity within a small radial space.
Applications: Primarily used in compact applications where high radial loads are present, such as transmissions.
Example Sizes: TA1010, TA1212.
11. RPNA and AXK Series
Description: The RPNA series combines needle and thrust bearings, while the AXK series consists of needle thrust bearings for axial load-bearing.
Applications: RPNA is used in multi-load applications like gear pumps, while AXK is ideal for thrust load applications such as automotive axles and pulleys.
Example Sizes: RPNA20/35, AXK2035.
12. NX and NKX Series
Description: These are combination needle bearings, with the NX series combining needle roller bearings and thrust ball bearings, while NKX combines needle roller bearings with thrust roller bearings.
Applications: NX is used in steering systems and industrial machinery, while NKX is preferred in high-load machinery.
Example Sizes: NX17, NKX20.
13. 81200 Series
Description: These are thrust needle roller bearings, designed to handle high axial loads in limited space.
Applications: Ideal for applications with axial load constraints like gearboxes and high-load transmission systems.
Example Sizes: 81206, 81210.
14. ZARN, ZKLN, ZKLF Series
Description: These are double-direction needle roller/axial cylindrical roller bearings with high radial and axial load capacities. The ZKLF series has a flange for easier mounting.
Applications: Suitable for applications where combined radial and axial loads are present, like in screw drives and rotary tables.
Example Sizes: ZARN1545, ZKLN0619.
15. KH Series
Description: These are linear motion bearings used in applications requiring smooth and precise linear motion rather than rotational motion, providing high accuracy and efficiency.
Applications: Commonly found in automated systems, robotics, and medical devices for linear movement.
Example Sizes: KH0622, KH0826.
Advantages of Needle Bearings
