Description of deep groove ball bearings with seals on both sides (60000-2RS type, 60000-2RZ type)
From the perspective of long life, JMZC OEM bearing selection requirements are:
(1) select a high load JMZC OEM bearing selection capability model, should take into account the price of imported bearings, or using more expensive, has a higher carrying capacity, or ordinary, and attempted to extend its service life bearings. Using of as Crown of symmetric roll child spherical roll child bearing cylindrical roll child bearing, hosted capacity high, reinforced tapered roll child bearing and ball bearing, deep groove ball bearing ball modified sexual of bus, or 70000CD series, and not deep groove bearing separate centripetal ball bearing, which has a high load capacity, bearing or improved stress distribution or a scroll body of number more, may is because has high of fatigue life.
(2) select the appropriate size of  bearings, so elections are the correct size, accurate calculation or an actual check bearings work load, speed and operating temperature. Mount the greatest influence on bearing life, while difficult to measure, but it should include accurate measurements. When the load measurements are very difficult to measure the actual power consumption of the motor, according to the projection of the transmission line and the low power loss all the way until you come close to calculating the actual load of the bearing. Calculating or measuring load is too large, greater will definitely reduce bearing fatigue life, try to remedy the situation, can be expected. If location permits an optional size large radial bearing is limited in size, wide wide bearings in the bearing cases, you should choose; if you can't use a wide JMZC bearings with higher load-carrying capacity of the bearings.

(3) select the appropriate material selection, JMZC  bearing materials should take into account their import prices and forced to use a vacuum or electro-slag steel melting, note perfect lubrication is needed, in order to breed can be expected to increase bearing fatigue life. Of course, such high-quality steels, bearing system with higher load capacity than bearings JMZC  to choose a more expensive cost, but it is difficult to close, the machine is very difficult to dismantle the bearing, or in mines, tunnels used to operate the machines, maintenance is extremely difficult circumstances, and sometimes it is to be considered.
