How do you measure a wheel bearing?

You can measure the dimensions of a bearing by using a vernier caliper like the one below or measuring accurately with a ruler. 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.

Bearings and seals are generally measured in inches. It is best to use a digital caliper, like # PTW80157, and measure out to 3 decimal places to find the most precise figure.

Are all wheel bearings the same?

Both employ the same physical characteristics of a bearing in that they house bearing spheres that are lubricated for spinning to allow the wheel to rotate. A major difference between the two is how they are assembled. Wheel bearings can be taken apart, lubricated and reassembled to be used again.

Are all trailer wheel bearings the same?

With standard bearings, the inner bearing is larger than the outer, but with parallel bearings they’re the same size. For heavier-duty trailers there are 1.5 tonne, 2 tonne, 3 tonne sets.

What size trailer hub do I need?

The first specification to determine is the number of studs/bolts and the ‘bolt circle’ diameter. Most 4 lug hubs have a 4” bolt circle and most 5 lug boat trailer hubs have a 4 ½” bolt circle diameter. Cargo and utility trailers with 5 lug hubs are commonly found with a 5” bolt circle.

How do I know what Bearings my trailer has?

In the wheel hub, the bearing on the inside of the hub flange (the side closest to the centre of the trailer) is called the inner bearing. The bearing on the outside is called the outer bearing. To replace them, you’ll need to know the size and type of the bearings in your trailer’s wheel hub.

What are different types of bearings?

Types of Bearings. There are many types of bearings, each used for different purposes. These include ball bearings, roller bearings, ball thrust bearings, roller thrust bearings and tapered roller thrust bearings.

What do the numbers and letters mean on bearings?

The basic code consists of the bearing series, which indicates the type of bearing, and the bore number, which specifies the bore diameter. The bearing series can be made up of letters and/or numbers that designate the construction, diameter series, and in many cases the width series.

Are NTN Bearings any good?

In testing the NTN bearings are generally the best irrespective of which seal is put on them. Their technical support is also very good (especially in the UK). The vast majority of NTN’s 6000 series bearings are made in Japan and they are sticklers for quality control. The only issue with NTN is supply.

How are bearings numbered?

A bearing number is composed as follows. The width series symbol and diameter series symbol are combined and called the dimensional series symbol. For radial bearings, the outside diameter increases with the diameter series symbols 7, 8, 9, 0, 1, 2, 3, and 4. Usually, 9, 0, 2, and 3 are the most frequently used.

What is a 6203 bearing?

Can bearings be over greased?

A common and costly problem in grease application comes from overgreasing bearings. Overgreasing bearings can lead to abnormally high operating temperatures, damaged seals, and in some cases, such as electric motors, energy complications and failure.

How do you measure a caliper bearing?

How to Measure a Bearing
  1. To measure the bore of a bearing you can use a vernier caliper like the one shown.
  2. To measure the outside diameter of a bearing place the jaws of the caliper around the bearing and close it until its a good fit but not tight, now read the value from the caliper.
