Inquiry (采购产品): Heavy duty ball bearings I own a Sun SX tricycle that has been modified to have a motor-assist. The motor causes the torque on the four rear wheel bearings to be much higher, and the bearings are wearing out after only a few hundred miles. I have a set of unused bearings that can be used as a model. What would be involved to create a set (or several sets) of heavy duty bearings that can withstand the extra torque requirements? **** Hidden Message ***** Linda Lingane 94306 USA Company: Stanford University Phone: 650-234-0671 E-mail: linda_lingane@yahoo.com **** Hidden Message ***** linda_lingane@yahoo.com
