Описание

The NKX series combined bearings consist of a radial needle roller bearing and a thrust ball bearing. The steel ball and cage thrust assembly of the thrust ball bearing is the same as that of the unidirectional thrust ball bearings in the 511 series, allowing for relatively high-speed operation. Axial positioning in one direction is achieved through the outer ring flange. The steel ball-cage assembly and the shaft washer can be separated for installation. As there is no sealing structure to keep grease inside the bearing, lubrication with oil is required. These bearings are standardly supplied without a pressed steel shield.

QIBR - NKX 15 Needle Roller Bearing Advantages and Applications

QIBR - NKX 15 Needle Roller Bearing Characteristics

NKX 15 Needle Roller Bearing, economical, space-saving, high efficiency. NKX 15 Needle Roller Bearing, can bear radial load and small unidirectional axial load, suitable for mechanical equipment with small space.

NKX 15 Needle Roller Bearing Features and Advantages

High load capacity: Needle bearings can withstand significant axial and radial loads, making them suitable for various heavy machinery and equipment.

High Precision: The manufacturing precision of needle bearings is high, with low rotational inertia, enabling high-precision operation.

Low Friction Coefficient: With a low friction coefficient, needle bearings effectively reduce frictional resistance during operation, minimizing energy loss.

Compact Structure and Lightweight: The overall structure is compact and lightweight, making it suitable for support structures with limited radial installation space.

Application: Needle roller bearings have a wide range of applications in industries such as automotive, aerospace, industrial machinery, construction and agricultural equipment, home appliances, shipbuilding, and medical devices.

QIBR - NKX 15 Needle Roller Bearing Optimization

Structural Optimization: Adjusting the arrangement of needles or the contact angle based on customer requirements and bearing operating conditions.

Cage Material: Material selection for the cage can be customized based on customer needs, including low carbon steel, stainless steel, PA66, etc.

High-Performance Materials: Choosing suitable materials based on customer requirements, such as DC03M, C15Mn, 16MnCr5, etc.

Heat Treatment: Carburizing or carbonitriding and quenching treatment of the outer ring and cage according to the bearing's operating conditions.

More customization: QIBR can design and optimize bearings based on customer operating conditions and requirements.

QIBR - NKX 15 Needle Roller Bearing Quality Control

Dimension measurement: Using various high-precision instruments to measure multiple dimensions of the bearings, achieving a maximum precision of 0.001mm.

Rotation accuracy: Measuring small defects or deviations on the bearing surface with a micrometer, with a measurement precision of up to 0.001mm.

Hardness measurement: Surface hardness is measured using a hardness tester, with an accuracy of ±0.5HRC.

Metallographic analysis: Internal metallographic structure is analyzed using a professional metallographic microscope.

Geometric tolerance: A contour gauge measures the bearing's geometric shape and relative position.

Noise monitoring: A vibration meter monitors vibration during operation to obtain noise data.

Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
