How do I identify which bearing I need?
How do I identify which bearing I need?
There are a few different ways in which you can identify which bearing you require for your application. Almost all bearings that we supply will be stamped with the bearing reference on the side. These are often found on the Inner Race, Outer Race or on the Shield or Seal.
Once you have found the part number then type that into our search box at the top of the page or use the search box below and you should find the bearing you are looking for.
If you cannot find the part number or the bearing is worn or damaged, you will need to measure the bearing to figure out which part you need. To do this you will need to use a Vernier caliper, and you will need to get three dimensions.
- Inside Diameter
- Outside Diameter
- Width
These three measurements will give you the dimensions that you will need to find the bearing you are searching for. Once you have the dimension sizes, type it into our search box in the following order; Inside Diameter, Outside Diameter, and width and our search engine will feed back the products that fit those dimensions.
What is the difference between an open type, rubber
What is the difference between an open type, rubber
The choice of bearing seal often depends on the environment in which it’s used. In moist conditions, rubbers seals are preferred to prevent rust. For dirty or contaminated environments, rubber seals offer better protection by keeping debris out. Temperature and speed requirements can also influence your decision, as some seals perform better under high heat or at higher rotational speeds.

What is C3 Clearance
What is C3 Clearance
C3 internal clearance in a bearing refers to slightly greater internal space between the balls or rollers and the races compared to standard clearance bearings. This extra clearance allows for thermal expansion during operation, reducing the risk of friction and heat build-up as the bearing reaches higher speeds. Although, the difference in clearance is minimal and is not visible to the eye, it plays an important role in performance of the bearing, especially when mounted in high-speed or high-temperature applications, by helping the bearing maintain efficiency and avoid premature wear.
The bearing has a different part number to what I ordered?
The bearing has a different part number to what I ordered?
Certain manufacturers have different references on their bearings and some put the references on the seals or shields.
Also, those bearings with 2 rubber seals or metal shields, can easily be removed to catre for 1 seal or shield. Therefore to speed up order processing, we may send you a bearing with 2 rubber seals or metal shields for you to de-shield.
