Further characteristic, retainer is provided with the retainer oil inlet hole, and lubricating grease, lubricant oil can smooth and easyly enter in the raceway of outer ring and inner ring through this oil inlet hole.
Further characteristic is equipped with О type circle between coupling shaft and the retainer, buffering and aligning coupling shaft and retainer.
Further characteristic is equipped with packing ring between retainer and coupling shaft, and packing ring is used to support retainer and little bearing keeps the gap.
Further characteristic, when using the cylinder rolling element, the cylinder rolling element is provided with cylinder rolling element oil inlet hole, is used for lubricating grease and is siphoned in the raceway groove, increases lubricated.
Bearing is in rotary course, and retainer and rolling element rotate synchronously, and retainer does not contact with the rolling element surface, and rolling element is the non-sliding friction of rolling friction.
This bearing adopts the seriation design, according to cylinder rolling element, steel ball rolling element shape difference, the bearing that design specification series varies in size.The bearing that can be used for specific (special) requirements such as deep groove ball bearing, roller bearing, tapered roller bearing, selfaligning roller bearing, selfaligning ball bearing, thrust roller bearing, angular contact ball bearing, needle bearing.
Effect benefit of the present invention is: retainer of the present invention and cylinder rolling element, steel ball rolling element are contactless, remove sliding friction, fricton-tight fricative solid pollution particle, and life-saving improves precision, reduces noise.The rolling element friction reduces, and heating reduces, the lubricated enhancing, and bearing can be realized high speed rotating.
