Beside ntn bearing price list, you should pay attention to “it”
What is your choice about ntn bearing price list? I help you.
I introduce more ntn bearing knowledge, hope it can help you choose.
1. Noise, torque and bearing structure
Rolling bearings, manufactured using precision machining technology, have low noise and torque. Deep groove ball bearings, cylindrical roller bearings, etc. have noise levels depending on the application. High precision miniature ball bearings have provisions for starting torque.
Such as motors, measuring instruments and the like require low noise, low torque instruments, suitable for deep groove ball bearings.
2. Rotation accuracy and bearing structure
Spindles, such as machine tools, require high accuracy of the gyration of the rotating body, and high-speed bearings such as superchargers should be used in high-precision bearings with accuracy classes of 5, 4, and 2.
Rolling bearing accuracy is specified for different projects. According to the structure, the level is different. According to the different bearing structure specified, high rotation accuracy compared with the radial runout of the inner ring.
Therefore, applications requiring high rotation accuracy are suitable for deep groove ball bearings, radial thrust ball bearings, and cylindrical roller bearings.
3. Installation, disassembly and bearing structure
Cylindrical roller bearings, needle roller bearings, tapered roller bearings, etc. The inner ring and outer ring can be separated bearing structure, more convenient to install and remove. Due to regular inspections, when the bearing is disassembled and installed more frequently, the above bearing configuration is more suitable.
Taper-aligning ball bearings, self-aligning roller bearings (small), etc., are easier to remove and install if sleeves are used.
