托辊配件影响托辊轴承的两个方面
Two aspects of roller bearing affect roller bearing
因素一，从尺寸上来说，一般的托辊轴承可以安装的空间是受限制的，它是有一定规定的，所以说一定不能随便乱用，要看好尺寸来安装。
Factor one, from the dimension, the general roller bearing can be installed in a limited space, it is a certain provision, so it must not be arbitrarily used, to look at the size to install.
因素二，转速和轴承的公差也要注意，托辊轴承的转速是根据尺寸，精度等因素确定的，轴承公差也要注意，不要相差太多。
Second, the speed and bearing tolerance should also be noted, the speed of roller bearing is determined according to size, accuracy and other factors, bearing tolerance should also be noted, do not differ too much.
因素三，不要老是拆卸，这样对零件也不好，会导致部件尼龙密封不严，从而无法进行运作。可能一些企业会因为场地不同而老是换地方，但是要尽量少安装以及拆卸。
Third, do not always disassemble, which is not good for parts, will lead to parts nylon seal is not strict, thus unable to operate. Maybe some enterprises will always change places because of different venues, but they should be installed and disassembled as little as possible.
