Description

QIBR offers two series of unsealed combined needle roller and angular contact ball bearings. The NKIA 59 series bearings can withstand unidirectional axial loads, while the NKIB 59 series bearings can withstand axial loads in both directions. These combined bearings consist of a radial needle roller bearing and an angular contact ball bearing, where the needle roller bearing handles high radial loads and the angular contact ball bearing handles light axial loads. With a low cross-section, they can operate at high speeds. These bearings are separable, allowing the inner ring to be installed separately from the outer ring, rolling elements, and cage assembly. Depending on the application, they can be lubricated with either grease or oil. When using grease lubrication, both the needle roller bearing and the angular contact ball bearing should be filled with the same grease before installation.

NKIA 5913 Needle Roller Bearing, strong impact resistance, compact structure, Inner diameter is 65 mm, Outer diameter is 90 mm, Total width is 34 mm, Weight is 0.64 kg, suitable for lawn mowers, clocks and optical instruments, etc., and is the most widely used bearing in working conditions with high stability requirements.

NKIA 5913 Needle Roller Bearing, easy to install and maintain, save space. NKIA 5913 Needle Roller Bearing, can withstand radial load and small unidirectional axial load, suitable for mechanical equipment with high durability requirements.

NKIA 5913 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 - NKIA 5913 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 - NKIA 5913 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.
