查阅说明书,ZX-5用的是TEFLON SHIELDED BEARING,这种轴承好不好呢,需不需要OP呢? 以下是摘自外国论坛的一个描述,看了个大概,但还不是很明了,请高手解释一下。 Metal shielded bearings have a small gap between the inner race and the side shield so they have less friction but gap allows dirt and dust to enter which means more frequent cleaning required. Teflon shielded bearings have teflon shield which actually rubs against the inner race of the bearing (albeit slightly), so they have a little more friction but keep dirt out better. Rubber sealed bearings seal even better than teflon, so you are getting maximum dirt protection but at a cost of more friction again. For dusty off road tracks I recommend teflon or rubber seals for all the hubs and diff outdrives. For touring cars shielded bearings are usually fine but if you don't like cleaning the transmission then put teflon or rubber sealed bearings on the diff outdrives. |
