Below are the description and part numbers to the additional spare parts you can purchase with your product.
There are a few different ways in which you can identify which bearing you require for your machine,
Almost all bearings that we supply will be stamped with the bearing reference on the side,
 |
 |
 |
 |
| On the Inner Race | On the Outer Race | On the Metal Shield | On the Rubber Seal |
These part numbers sometime are not the easiest to read therefore the bearing might require cleaning with an oily rag, or you may need a magnifying glass to see what the part number is.
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.

Yes. Kluber, Shell, and Molykote offer NSF H1 food-grade lubricants suitable for use in food manufacturing industry. Also, many of the brands we sell offer biodegradable or low-toxicity options designed for environmentally sensitive applications.

We stock a full range of bearing maintenance tools including pullers, induction heaters, mounting and dismounting tools, alignment tools, and infrared thermometers. These tools are designed to ensure safe handling and damage-free installation or removal of bearings. Our product pages include detailed specs to help match tools to your specific requirements.
Shaft misalignment is one of the leading causes of premature bearing failure— especially in heavy-duty equipment. Even slight misalignment can reduce bearing life by over 50%, leading to increased wear, vibration, heat generation, leading to unexpected downtime. To prevent this use shaft alignment tools to ensure shafts are correctly aligned during installation or maintenance. Laser alignment systems are especially effective for high-accuracy setups. Investing in proper alignment solutions not only extends bearing life but also improves equipment efficiency and reduces long- term maintenance costs.
This question normally comes down to the environment the bearings are being used it. For example, if the bearing is being used in a moist environment then you’d choose rubber or metal as the metal is more likely to rust.
If the environment is very contaminated, then you might choose a rubber seal to keep the contaminants from damaging the inside of the bearing.
Your decision could also come down to the temperature the bearing needs to work to or the speeds it needs to reach.
