SKF self-aligning ball bearings 1202ETN9 of Changzhou Innovene letter SKF dealer a knowledge-based

SKF self-aligning ball bearings, with two bowls and the arc in the outer ring raceway. Therefore, bearing self-aligning and the angle between the axial bearing error. Especially suitable for easy shaft deflection and misalignment conditions. In addition, auto-aligning ball bearings, friction is the lowest of all the Rolling, so even at high speed is still only a smaller temperature rise. 

 SKF auto-aligning ball bearing design: 

 (1) open design 

 2 sealed bearings 

 With extended inner ring bearings 

 SKF130 and 139 series of large self-aligning ball bearing was originally designed for paper machine equipment design, can be used any more than the demand for low-friction load demand conditions. 

 SKF self-aligning ball bearings suffix meaning as follows: 

 C3 ------ radial clearance than the ordinary group 

 ------- Optimized internal design 

 K ------- tapered bore, taper 1:12 

 M ------- machine cut brass cage 

 The the TN9 ----- injection molding of glass fiber reinforced nylon 6,6 cage 

 2RS1 ---- on both sides with a steel skeleton Ding Qing rubber contact seals
