Remember most bearings sizes are full mm or inch sizes. eg: 9.53mm would be 3/8 inch. If you measured at 9.5mm its probably an inch sized bearing. To measure the bore of a bearing you can use a vernier caliper like the one shown.
How do you determine bearing size?
Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches.
How do I choose the right bearing?
How to choose the right bearing for your application:
- Find the Bearing Load & Load Capacity. First, know the type and amount of bearing load that your application will place on the bearing.
- Know the Rotational Speed of Your Application.
- Factor in Bearing Runout & Rigidity.
- Find the Right Lubrication for Your Bearings Needs.
How do I find my bearing number?
Measuring your bearing: Most bearings are measured in three ways, the inside diameter or (ID), the outside diameter or (OD) and the width or (W). It is important to note that our bearing measurements are all done in the following order: Inside diameter (ID) x Outside diameter (OD) x Width (W).
How do I know what size my big end bearings are?
Look at the back of the bearing for the size that is stamped into the edge of the bearing. If you are only replacing the bearings, you will want the same size that is stamped into the back of the bearing. It may be std., . 010, .
Does it matter what bearings you get?
Almost every skateboard bearing is the same size and will fit on any skateboard wheel and truck. When choosing your bearings, it is important to think about your experience level and riding style. Bearings with higher-quality parts will be faster and more durable.
How do you order bearing sizes?
All bearings will have an inner diameter (ID), an outside diameter (OD) and width (W). Bearings are sometimes referenced by these dimensions, in that order: ID x OD x W.
Which bearing is suitable for high speed?
Ball Bearings are used to take heavy as well as high-speed loads.
How do I know if I need an oversized rod bearing?
The outside diameter of the bearing is what fits into the engine block, and the crankshaft rests on the inside diameter. An oversized bearing has the same inside diameter but a bit more material on the outside diameter. An undersized bearing measures the same outside but is thicker on the inside.
What are undersize bearings?
An undersized bearing has extra material thickness on the inside of the bearing facing the crankshaft journal. Undersized bearings are used when a crankshaft has been machined or ground undersize. Oversize bearings have more material on the outside facing the bearing housing bore.
What is a big end bearing?
Big End Bearing – Located at the ‘Big End’ of the Connecting Rod, where it connects to the Crankshaft. Flange Bearing/Thrust Washer – Located at the end or mid-way through the Crankshaft. Small End Bearing – Located at the ‘Small End’ of the Connecting Rod, where it connects to the Piston Gudgeon Pin.
Are there different size bearings?
Unlike the wheels in which they fit into, all bearings have the same dimensions– 8mm (inner diameter), 22mm (outer diameter), and 7mm (width). Each wheel requires two bearings that are usually separated within the wheel by a spacer. Bearings are measured by an ABEC rating system (1, 3, 5, 7, and 9).
Do bearings fit all wheels?
Skateboard bearings are the round metal pieces that fit inside the wheels to mount the wheels to the axle. Regardless of wheel size, all skateboard bearings are the same size and will fit any skateboard wheel that Warehouse Skateboards sells.
Are ABEC 11 bearings real?
ABEC from a precision standpoint refers to the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). ABEC precision levels do indeed stop at level 9 (there is no ABEC 11 precision level).
What size are 608 bearings?
Miniature Ball Bearings 608 – 8X22X7mm Description
The 608 is a 8 mm Ball Bearing that can be used in many rotary and factory automation applications.
What size is a 6204 bearing?
DIMENSIONS
| d | 20 mm | Bore diameter |
|---|---|---|
| D | 47 mm | Outside diameter |
| B | 14 mm | Width |
| d1 | ≈ 28.8 mm | Shoulder diameter |
| D2 | ≈ 40.59 mm | Recess diameter |
What size is a 6202 bearing?
The 6202 15 mm Ball Bearing Inner Dimension 15mm X Outer Dimension 35mm X Width 11mm is an open style ball bearing designed for high rotational speeds and high dynamic loads.
Which bearing brand is the best?
Top 10 Bearing Brands in The World

Which is better ball bearing or roller bearing?
As a general rule, ball bearings are used at higher speeds and lighter loads than are roller bearings. Roller bearings perform better under shock and impact loading.
What RPM is considered high speed for a bearing?
Anything higher than 3,000 fpm is considered high- speed. Keep in mind, however, that low linear speed does not necessarily mean low angular speed. As Fig. 1 shows, a low-speed bearing with a pitch line diameter of less than 1.9 inches can rotate as fast as 1,000 rpm.
Can I just replace rod bearings?
If you replace just the rod bearings with the engine in the vehicle, as long as you do it correctly, there is nothing wrong with that. It is important to note that removing the pan and the caps will be necessary to inspect the bearings and crank journals, regardless of whether you can do this.
