If you can't obtain the bearing reference number, you can use an accurate measuring tool such as a digital caliper to measure the inside diameter of the bearing (a ruler or measuring tape wouldn't be accurate enough.) You can also measure the diameter of the spindle where the bearing would ride. Another option would be to knock out one of the bearing races and get the reference number off the race. With the race number, we can usually find its matching bearing.
