● Introduction

Needle roller bearings with cage consist of ferrule, needle roller and cage. The bearing has small cross-sectional size, small footprint, light weight, high limit speed, high load capacity, and high transmission power. The shape of the needle roller is slender and the outer diameter is generally not more than 4mm. Bearings with or without an inner ring are used depending on the application. Bearings are divided into needle roller bearings with ribs and needle roller bearings without ribs. The rib of the bearing is on the outer ring, which can be a fixed rib or a spring lock ring. If the raceway of the shaft is quenched and ground, the removable inner ring may not be installed. If the shaft cannot be used as a raceway, that is, when grinding for hardening of the shaft is not available, such needle roller bearings with cage can be used. There are lubricating oil holes on the outer ring and inner ring of the bearing. According to the needs of use, lubricating oil can be added through the outer ring or the inner ring.

Caged needle roller bearing are mostly used in machine tools, automobile gearboxes, generators and other fields.

● Bearing Series

The types of the bearings include NK series, NKS series, RNA48 series, RNA49 series, RNA69 series, RNA69..-ZW series, RNA49..-RSR series, NKI series, NKIS series, NA48 series, NA49 series, NA69 series, NA69..-ZW series, NA49..-RSR series, RNAO series, RNAO..-ZW series, NAO series, NAO..-ZW series, RPNA series and PNA series.

● Production Details

◆ Guarantee of surface quality of bearing ring turning

1. The rigidity of the lathe should be good, the power should be large, and the working performance should be stable.

2. According to the different properties of the machined surface, the tool should choose different geometric parameters, especially the shape and angle of the tool tip and the width of the blade involved in cutting should be appropriate, follow the reasonable cutting specifications and the rational use and sharpening system of the tool. clean up the tool in time. Steel chip belt to avoid scratching the processed surface. remove residual burrs in time.

3. For some unavoidable surface defects, it should be controlled within an appropriate range.

4. The blanks for turning processing, especially the forging blanks, are required to be uniform and compact, without internal defects, and with uniform allowances.

◆ Detect the accuracy of bearing finished products

The precision inspection of bearing finished products includes dimensional accuracy and rotation accuracy, as follows.

1. Dimensional accuracy includes: inner diameter (Δdmp, Vdsp, Vdmp), outer diameter (ΔDmp, VDsp, VDmp), width (ΔB, VBs, ΔC, Vcs).

2. Rotation accuracy includes: runout (Sd, Kia, Kea, Sea, Sia), variation SD of the inclination of the outer surface busbar to the end surface.

● Bearing Noise

When the vibration of the rolling bearing propagates to the radiating surface, the vibration energy is converted into a pressure wave, which is then propagated through the air medium, it is called acoustic radiation. Among them, the 20~20000Hz part of the sound radiation can be received by the human ear, this part is the bearing noise, so the vibration of the rolling bearing is the source of the noise. Different bearing noises come from different types of bearing vibrations, such as raceway noise, which is inherent to the bearing, it is an unavoidable basic characteristic of the bearing during operation, it is called basic noise.
