Single seal bearings (code Z or RS, said 60 bearings) with iron and plastic seals, KA nylon retainer bearings can also be added a bearing seal known as KAZ or KA | 2RS. This type of bearing both open bearing installation grease convenient, but also has a good seal. Because a lot of bearings installed only one side of the storm drain on the outside.
Compared with plain bearings, the advantages of rolling bearings:
(1) under normal conditions, the efficiency of rolling bearings and hydrodynamic lubrication bearing rather, but mixed lubrication bearings to be higher;
(2) radial clearance is relatively small, to the angular contact bearings available preload can be used preload to eliminate clearance, high precision;
(3) for the same size of the shaft diameter, rolling bearings smaller than the width of the sliding bearings, the machine can make the axial structure of compact;
(4) most of the rolling bearing can be subject to radial and axial load, the bearing assembly structure is simple;
(5) less consumption of lubricants, easy to seal, easy to maintain;
(6) does not require useful non-ferrous metals;
(7) a high degree of standardization, mass production, low cost.
Compared with the sliding bearing, rolling bearing shortcomings:
(1) to withstand the impact load capacity is poor;
(2) high-speed heavy-duty load bearing life is low;
(3) vibration and noise;
(4) radial size than sliding bearings.
