subject: Sounds Reduction With Coated Bearings [print this page] From home ,office equipment to small business offices and especially big corporate and business environments. The machines that are used to deliver the printed page exist in virtually all of these. To many, among the most important considerations of deciding whether or not to have these machines nearby is the noise factor of a certain unit, perhaps unknowingly with a significant source of the noise coming directly from the feed roller bearings.
Anyone that works in an office environment already understands and accepts the reality that these machines are necessary and important the flow of the office. In a small office where maybe only one printer may be the workhorse for all of the printing and fax needs, the noise coming from this machine is begrudgingly accepted as ''norm''.
Since these equipment consist of mechanical parts that by their really nature do generate noise during operations, one must consider the physical placement of such equipment so as not to interrupt the flow of the office and possibly hinder productivity.
To much better understand the importance of maintaining office equipment noise as low as possible, think about the era of a busy publication copy room where dozens of manual typewriters were clicking away. Sure, those days are long gone and with the evolution of all equipment that provide the printed page, the word ''digital'' comes to mind. Almost all printed material today begins on a computer using a ''soft'' keyboard (minimal sound) and ends up being printed in a format that meets the desires of the particular user, eventually making its way to a computer printer.
Thanks to many amazing innovations in technologies over the years, engineers have made great developments in their hard work to eliminate or greatly reduce the noises of paper delivery machines, particularly when these machines are used in large corporate environments. As, I've already mentioned this noises is generated by the mechanics of the particular unit. More specifically, the feed roller bearings are the main reason due to the fact these bearings can spin at a high RPM, which is what produces the noise.
In addition, when these kinds of bearings start to wear down, the first sign of extreme wear is of course, a noise that gets louder with use. Now, if several equipment together begin to encounter bearing wear, one can imagine how quickly the noises will worsen.
One of the innovations in bearing design with this specific application is that of the coated bearing. As, I've mentioned, noises mitigation is very important in an office environment. That said, engineers have developed a process that allows urethane to be bonded directly to a standard ball bearing.
Note that this process is versatile enough that different sizes of bearings can be modified for use with the urethane coating. This topic of urethane coating would not be complete without mentioning that in addition to urethane coating of feed roller bearings, urethane rollers are actually available. The designs of these rollers offer various styles depending on the application and include segment rollers, crowned rollers, idler rollers, drive rollers, NIP rollers and retard rollers,
Finally, to guarantee an effective fit and long lasting, trouble-free operation, rollers are typically made to order.
