NSK Bearings 2303 Self-aligning Ball Bearing 2303 High Precision Ball Bearing 2303 Sizes 17*47*19

1.The Introductions of Self-aligning Ball Bearing:

1:The double-row self-aligning ball bearing has a cylindrical bore, steel cage, and normal clearance rating.This bearing has concave sphered housing rings to compensate for static angular misalignments between the shaft and housing in applications subject to shaft deflections or mounting errors. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds.
2:The bearing has a straight bore for fitting on a conventional cylindrical shaft. Rubber seals on both sides of the bearing keep out contaminants such as dirt and grime and hold in lubricant applied at manufacture.
3:This bearing has a steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise.
4:The ball bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion.

2.The Features of Self-Aligning Ball Bearing:
1.Self-aligning bearing for applications subject to shaft deflections or misalignments between the shaft and housing
2.Straight bore for fitting on a conventional cylindrical shaft
3.Steel cage evenly spaces balls for reduced friction, vibration, and noise
4.Normal radial internal clearance for applications where thermal expansion is not a factor

3.The Advantsges of Self-aligning Ball Bearings:

1:Long-life with high quality

2:Low-noise with strict controlling the quality of bearings

3:High-load by the advanced high-technical design

4:Competitive price, which has the most valuable

5:OEM service offered, to meet the customers' requirements

4:The Applications of Self-aligning Ball Bearings:

Self-Aligning ball bearings to withstand heavy load and impact load, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, petroleum, paper, cement, sugar and other industries, and general machinery.
