When doing any kind of budgeting or ordering it is important to remember those shop supplies that most people will take for granted -- until they run out!
Loose Ball Bearings
To determine what size a bearing is use a ruler. The most common sizes are:
- 1/4"
- 7/32"
- 3/16"
- 5/32"
- 1/8"
Like anything, the larger quantity you buy, the cheaper the rate. You can buy bearings from bicycle part distributors but you can also get them from bearing companies.
Grades
Bearings come in different Grades, the important thing to remember is quality and cost increase as the grade number gets lower, so 100 grade is better than 1000 grade. Grade 25 is the best you can buy, but you can use bearings all the way up to grade 800.
NOTE: Avoid mixing different kinds of bearings as they are made in batches, and bearings from the same batch work better together. It may be tempting to consolidate bearing containers when one gets low, but it is better to just let them run out.
