In the process of assembling of bearings, there are rubber seal, steel seal, open type and UG that we are familiar with. Besides, there is still a common assembly method, Full Complement Bearings assembling which is often neglected. Rubber seal: it solves the problem of dust and leak resistance. Open type: it solves the problem of putting some lubricant wherever and whenever we need put it to ensure the best lubricating state of bearings. UG: it solves the problem of bearings' requirements in different usage environments between open type and seal. But what problems do the Full Complement Bearings assembling solve? For example, the common deep groove ball bearing: 6203ZZ. Dynamic load: 9550N Static load: 4800N Grease lubrication: 17*1000rpm Oil lubrication: 20*1000rpm If we use the crowded ball bearing: 6203 Full Complement Bearings. The corresponding parameters will become: Dynamic load: 14000N Static load: 7000N Grease lubrication: 2000rpm Oil lubrication: 3000rpm In conclusion, Full Complement Bearings solves the core problem: load. It adds using load of bearings based on the original unchanged design in order to solve the problems of usage environments and requirements. But it also brings into the question: the rotation speed (without retainers, it fails to guide the rolling elements' rotation in one direction. At the same time, the contact between one roller and another greatly reduces the rotation speed of bearings during rotation.). Besides, there are holes holding balls in the inner and outer rings of bearings, the dead clamping situation will occur due to too fast rotation speed.
