HRB bearing - What are the main structure form of deep groove ball bearing?

HRB bearing - What are the main structure form of deep groove ball bearing? HRB bearing expert to tell you about the following: ( 1) Basic deep groove ball bearings to install, seal, with no special requirements, all can use this kind of structure. （ 2) Outer ring has a locking groove deep groove ball bearings N there open install the snap ring groove on the outer diameter of deep groove ball bearings, the load can simplify after stop ring bearing in the bearing hole axial positioning, narrow parts of axial size, this kind of bearings can only carry axial load in smaller. This kind of bearing with stop ring bearing, code-named NR (after 3) Deep groove ball bearings - with dust cover Z and - 2 z with dust cover deep groove ball bearings, bearings with steel dust cover, prevent grease leakage and external foreign invasion. With a dust cover deep groove ball bearing is divided into a dust cover ( - Z） And the two sides with dust cover ( - - - - - - 2Z） 。 Dust cover and the radial clearance between inner ring guard, is a non-contact seal, so the friction torque is small. Compared with the bearings with seals, compared its bearings with seals, the dust cover performance is poorer, single limit rotational speed is higher. Bearing assembly time to fill in the right amount of lubricant, the installation without washing and add lubricant, when used within the allowed lubrication during also need not add lubricant. This kind of bearing is suitable for the dust, and lubricating oil supply and check the lubrication situation inconvenience widget. Bearing a dust cover, another outer ring groove, stop its code-named - ZN。 （ 4) With seals of the deep groove ball bearings with sealed bearing seal structure can simplify support, and improve the bearing performance, so the product development soon, the demand for more and more big, has accounted for about 90% of deep groove ball bearing production. Bearing seal structure is varied, have a light contact seal, non-contact seal and contact seal, etc. , to adapt to the different needs. Main function is to prevent the grease leakage and external foreign invasion. One side with seals ( - RS) And the two sides with seals ( - 2 rs) Deep groove ball bearing, seal lip contact with inner ring guard radial, as the contact seal, the sealing effect is good, but the friction resistance is bigger, the limit rotational speed is low. If do not contact with inner ring guard, sealing lip is non-contact seal, main structure - RZ and - 2RZ。 The speed limit is the same as the basic deep groove ball bearings. Bearing to fill in the appropriate lubricant, when it is assembled without washing and add lubricant when install and use. The suffix LS for ring slot. All that comes with a live two sealing ring, one or two dust cover goods a sealing ring and a dust cover of the rolling bearing called closed type bearing, rolling bearing without sealing ring and dust cover is called open bearings. Closed type bearing and open type bearings are the same size. Deep groove ball bearings and has a variety of variant structure due to the different conditions of use, their different characteristics. In addition to the above structure, with the ball gap of deep groove ball bearing, double row deep groove ball bearing, carbon steel deep groove ball bearings, etc. With deep groove ball bearing of ball gap due to have put the ball on inner and outer gap, therefore, put the ball number more than ordinary deep groove ball bearing, so the load capacity is large, single limit rotational speed is low. So there is a ball gap, so can only carry axial load in one direction.
