The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Flanged Ball Bearings

These flanged ball bearings are steel replacement bearings for caster and wheel hubs. Sizes on this page are 1/2 in, 5/8 in, and 3/4 in inside diameter, all with a 1-3/8 in outside diameter. The flange seats the bearing in the wheel hub so it does not walk sideways under load. Steel races suit dry indoor industrial carts and fixtures. Measure the old bearing ID, OD, and flange before you order. Do not force a bearing into a worn hub that is out of round. Match the bore to your axle before you place your order today. Read the listing for the exact ID and OD shown. No pound capacity is printed on these bearing titles. Verify the SKU matches your old unit before you buy. Sizes below are per bearing as each listing states. Related metal wheels: metal wheels. Brand aisle for Durastar builds: Durastar casters.

Before you order

Match bore, length and thread on the old part before ordering flanged ball bearings.

Check that replacement flanged ball bearings fit both the wheel bore and the axle diameter.
