Raymond mill bearing how to pick?

As a manufacturer of Raymond mill site Xiao Bian, I see the question "how the election of factors of raymond mill bearing" a little sad. From the manufacturer's point of view, what bearing equipment selection for a job, is a process, is a partnership of choice, the choice of what kind of bearing on the future operation of the entire device has a decisive role, so in this respect the manufacturer always the most professional, best intentions. As customers ask the question, in fact, I can understand, because some customers spent tens of thousands or hundreds of thousands to buy back a device, with a few days equipment fails, a look into the problem appears on the bearings, certainly You will want to be sure that manufacturers cheaper, install a bad bearing. He began looking around to buy the bearing, in the store, ask around the Internet, we asked some basic questions to select the bearing. For bearing for equipment operation as a core component, the manufacturer is not necessary in this regard tampering, because the machine could not use one or two days when it is required to use long-term, say for Raymond this equipment, if Really bad bearing, replace it is very troublesome thing, the manufacturers have had to send technical personnel to the scene, the machine disassembled to replace, not only a waste of time, but delays in customer's production schedule. For components inside the device, and the operation of the device has a great relationship habits, as Raymond machine itself, in line with the production of relatively large, some customers to schedule production will increase the work load, the machine is a very large damage, this will inevitably will be shortened equipment life, in which the client is in the process of using the mill did not do maintenance work, because bearings need periodic lubrication.
